Scotty, I bought a '95 Jeep Grand Cherokee. That's my horror story. The usual; fuel pump went bad, electrical issues plagued it, battery never stayed charged. After everything was fixed it still wouldn't run. I traded it for a running 1993 2.3L, 5-speed Ford Ranger, which ran for five years, no problem. I gave it away when I bought my next car.
I have always done it and it has never hurt a car I've ever had. I have a new one now so I am not going to top off like I once did. first time for everything😱
I'm one of those guys, topping off the fuel tank. After doing some research, I got here. I think is time to change my habits and follow the mechanic advise. Thanks Scotty.
Scotty - I really enjoy your new approach of single issue technical tutorials done in such a thorough manner. Excellent video as always, thank you very much.
We only wish that other mechanics would be this knowledgeable. But unfortunately, most intelligent folks choose a different career path. And also the honest mechanics are hard to find. If a mechanic opens his own shop and is smart and honest he can make a very good living. Reputation is everything.
Brings back the words of wisdom my father in law imparted on me, “don’t fix it if it ain’t broke”. The following week, he had to have his fuel pump replaced because the fuel filter I suggested he replace (I’m a factory trained mechanic), clogged and burned up the fuel pump. Oh, and stop the extra pump, waste of time.
I spent way too much time searching under the hood, and following the fuel line back to the tank when I got my Corolla. When I buy a new (used) car I automatically change all the filters and fluids just so I know where I'm starting from. Eventually I learned the only fuel filter is in the tank. I'll leave it alone for now.
I never had one of those break. These new-fangled electric pumps seem to go 130-150K and they're done. So is your car at that point. Call a tow truck. Wherever it is.

Very good article, with brisk delivery and logical narration. The points about overfilling were clear and persuasive. And viewers got a bonus-- the argument against running on a low fuel tank (below one-fourth tank) have not been made anywhere else (on RUclips). Running low risks bringing debris into the fuel line and damage to the fuel pump. And how many drivers know they have a fuel filter? The old myths about gasoline volume shrinking during cold weather or overnight at the gas station were widely accepted, but few reflected that wineries use the constant temperature of soil to maintain their wine fermentation process. Likewise, the Germans with their beer, because soil is a good thermal insulator. Although cellphones are not documented for causing a single flash fire at a gas pump, anti-static measures at gas pumps are more persuasive, especially in winter. Dry air allows a static charge to accumulate on even hand-held, plastic gas containers, which is why gas stations require such containers to be placed on the ground/concrete before filling. * I especially like the improved signature opening
Good afternoon,Mr.Kilmer! It is so good to see your program on RUclips. I wanted to thank you,for program today,about Not over filling your gas tank,and to have at least,a quarter of tank of gas in your car.I hope you're having a good week- end,and I wanted to wish you,a Happy Fourth of July Mr.Kilmer. Sincerrly,Nancy Sanders,MO.
They used to have the glass canisters with the gas pumps showing in the old days to ALSO show that you were not getting ripped off. You could actually SEE how much gas was going into your tank and did not have to blindly 'trust' the pump meters like we do today (or that the government stickers are legit and accurate for when they are calibrated).
.....you young pups forget the real claim to fame of the old glass canister pumps.....they worked thru power outages....you filled canister by manually pumping gas up into canister and it gravity fed into vehicle....
This format of video ? From Scotty ? This is a dream come true ! Your narration and diction is on point and your level of knowledge doesn't dissapoint.
Good Info As Always Scotty True Story. > Waiting at the bank to cash my check years ago and across the street a tanker truck was filling the tanks while i was i line. Was looking over at the gas station and a Geyser of gas shot up from the stations venting system. I was like uhh hope nobody is smoking as this could get ugly. Got my check cash and high tailed it outta there pronto. I was not gonna be a fireball victim that day hahaha
I’ve seen on your show where you said . don’t overfill or top off your gas tank. One thing you didn’t say inn this video was that overfilling or topping of can make your service engine soon light come on. Well I’ve been topping my 2003 ford E250 off for the past two years . Never had a problem. Then about a month ago the service engine soon light came on. Had it checked and the guy at Winchester auto parts checked it and couldn’t tell me what the problem was. So he cleared the code. It stayed off for another couple of fill ups. Still topping it off. Then it came back on. Well following your advice on another video, saying not to ever top it off or a service engine soon light would come on so my landlord mechanic cleared the code, and I haven’t topped it off cents it’s been about a month now, and no light comes on, so I want to. Thank you for your great advice because I probably would’ve never figured out what it was. Thank you for your great advice. Keep on giving that great advice out. I appreciate it and so many other people you do a great job. Keep it up Godspeed.
I had an 07 Focus....i went through 4 or 5 fuel pressure regulators...found out it was because i over-filled the fuel tank...i stopped that & never had another issue
Another excellent documentary presented by Scotty. Although I was aware of most of the points covered here, I enjoyed watching it presented in a video. And being of the old school variety, I will admit to being unaware of the damage overfilling a tank can cause to the evaporative recapture system.
For me (from doing this stuff) a 1/4 tank marker is always Empty. This was beat into my head when they 1st started to put the pumps in the tanks. When you have to drop the tank to change the pump and it always came in with a "near full" tank of gas in it. Ultra Heavy, Hard to syphon/pump out, pretty much guaranteed to get a nice stinky Gas Bath doing it. Yep, 1/4 tank and I always look for a gas station.
I was a transmission builder (we and the electronics guys are the highest paid individuals of any full-service repair shop) and one of the rules with the pump in an automatic transmission is if it can move the vehicle, the transmission has enough fluid in it to keep from burning up the pump. Same with a fuel pump. If it can run the engine, it is getting enough fuel run thru it to stay cool and lubricated. Simple as that. Now, consider never letting the tank run lower than 1/4 full. Every time you fill up, you are only replacing 3/4 of the fluid in the tank at the most. The rest is stale, and over time, this could possibly cause running problems.
As a fuel tank driver here in NJ I can attest to the tanks temperature. The only thing that changes with hot or cold temperatures is the vapor in the tanks. With cold temps I deal with more air pressure in the tanks.
I have a 87 Bronco 2 my engine would shut off while driving down the road, I replaced my original gas cap with a new one that fixed it no more engine cutting off while driving. A scary situation if you are on the highway.
You can say and be right about not topping the gas tank I still did it, only the time I had to go over the Andes mountains. A five hour trip end being a 22+ hours trip finding alternative routes and being stuck in the road due to the snow. At the end of the day I was worrying about running out of gas but make it to my destination with less than a 1/4 of a tank of gas. On a 2013 Mazda CX-5.
I drive a plugin hybrid and it’s so fuel efficient I actually don’t fill it up the whole way. No problem with topping it off here. I’m so glad I picked it over an electric car. I may go fully EV in 15 years or so (or 20, knowing Toyota).
Scotty - you're always educational! And I enjoy these vids. For the future - could you cover something like EMPs. How it effects the cars and if there are any that would hold up better if exposed to an EMP.
If you can find the filter under the car or hood on a 2001 thru 2005 Civic let me know because I only ever have seen the filter sock on the fuel pump inside the fuel tank, And never had one go out yet even with two cars with over 300,000 miles, the only reason I know this is because I remove the rear passenger seat and access cover then the fuel pump from the car so I could see if any crap was floating around in the tank, but NO it was as clean as the day it was made, But if course Honda uses HIGH Quality DENSO PUMPS.
@@raymondreiff8170 that’s good to know! I have a ‘16 Civic - fuel system seems to be doing fine, but still planning on replacing the fuel filter at 150k miles.
@@carlovanrijk4039 my current vehicle has 4 filters. One life time filter in both fuel tanks, only replaced if the pump goes out. Then a 10ppm fuel filter/ water separator and 2ppm main fuel filter before it goes into the high pressure pump. The high pressure section runs at 24000psi. Yes 24 thousand psi.
me too with my '05 Jeep Wrangler. I run it right down until the fuel light comes on then some more, then fill right up with fuel squeezing in as much as possible. and it doesn't have a fuel filter. 200k miles and still going strong with same old fuel pump and charcoal cannister.
Well I had to replace that EVAP canister on my 2000 Grand Am and my mechanic even told me not to do that but I still get more gas by continuing to fill it up. So I'm not sure, Scotty says you don't see any significant reasons to doing that but I can get up to half a gallon by doing that and really I've only been doing that because of the crazy fuel prices, but maybe its not a good thing if I'm sending fuel back to the pump. Newer cars have more range due to fuel efficiency and larger tanks so I'm looking to get a Honda Civic or Accord in the future.
Before I got my F150 I had a 2011 GMC Sierra. I always topped it off. That is, until I had to replace an evaporator purge valve. The truck started extremely rough and I eventually got a check engine light. Thank goodness it was an easy fix.
I bought a 79 Ford Econoline van that had been sitting for about two years but it ran very good and I had it for a while, before I let the gas hand go to the E . It sucked up trash out of the tank and never ran right again.
Please take Scotty advice. I had a 2003 Elantra as my first car that the previous owner jacked up the system. I dealt with the clicking issue until I fixed it myself. The charcoal canister was bad, and allowed charcoal to enter into the vapor lines in such. I replaced it and cleaned out the lines for a temporary fix. Because the issue was so bad, it got further into the fuel tank. I had a mechanic clean out the fuel lines and the issue was no more
I recently purchased my 2011 Corolla from someone who always overfilled to "save time and trouble". I went over his repair receipts and he had to replace the vapor canister twice from problems such as leaking.
Scotty, most cars from 2008 on have the filter built into the fuel pump assembly not easy to get to to change previous models years the filter was in line towards the engine bay! I think on a lot of the Denso pumps They just have a fuel strainer on the end
I’ve been in the habit of topping of the gas tank since 1972. I heard vehicles from 1996 and newer that over filling is a bad idea. I learned this too late. My current 2006 pickup, I’ve owned since new, with 135K on the odometer. The past few years it’s gradually getting worse at accepting gas into the tank. I got to the point where it would only accept 3.5 gallons (on empty) very slowly, and pump would not fuel any further. I paid mechanic about $1300. (To repair). The fuel goes in very slowly, but I can fill it. I wish I could have heard this sooner. When I got my truck back from the mechanic, (a week ago), I filled up in the normal way, by topping off the tank, so it is absolutely full. I realize my conduct caused this problem (now).
well done Mr. Kilmer I have been over filling my Camaro for............... well, a long time. I don't needa tell you how much un those fuel pumps are to replace. I knew too empty was less then ideal (for the reasons you stated) but never knew too full was even a thing. R.B.G. Manors Creep
I used to top off all the time with my vehicles and never had a problem. I began doing it with my new Volkswagen atlas. The check engine light came on and the dealer had to replace the charcoal evap canister because it sucked in fuel. Luckily the warranty covered it but since then I’ve stopped that bad habit.
I worked for Toyota for years, and we have had to change several charcoal canisters due to gas tanks being overfilled. Scotty is right, the charcoal was saturated with liquid gas where it should only handle fumes. $500-$700 repair because of squeeze in a few extra clicks.
Mr. KILMER'S level of INTELLIGENCE is absolutely, STAGGERING! I thought that I was fortunate enough, to have some "smarts"; however, compared to his intellect, I have come to the conclusion that I'm indeed, a "bone head"! Your millions of subscribers LOVE you, SCOTTY. THANK YOU FOR HELPING US!! ❤❤❤❤ Roland Singh, Canada 🇨🇦
I read in my old car’s (15 Hyundai Veloster Turbo) manual to never pump further after the pump “clicks” so I never have topped off, but I always wondered why not to-my mother did though (I will have to teach my mother this).
My 79 Dodge pickup was the same way. I used to make the trip from Great Lakes Navy base to home near DC a couple times while up there. Ran out of gas twice in the same exact place in Indiana on US-30. Slow learner..... Why US 30? Ohio State Patrol would give you a ticket for 1 mile over the speed limit on the Ohio Turnpike. I would follow the trucks on US-30, they would run 90mph and never see a cop.
Changing the fuel filters is often more involved than it used to be. You have to pull seats and get into the gas tank in a lot of cases. Or drop the whole tank.
Honda and Toyota both have one-way valving systems to stop liquid back feed to happen from the tank to the vapor system. Along with bubble top tanks designed to have a 1 liter air bubble at the top of the tank you can not fill with fuel. These have been in use for over 8 years.
Back in the 70's I was maintaining and driving a fleet of Dodge B300 passenger vans. They had steel tanks which could hold 26 gallons, but because of a bad filler design, you couldn't easily get more than 22 gallons into those tanks. It was bad enough that Dodge revised their "specifications" to a 22 gallon tank. When I was patient and let the tank burp, I could get the extra 4 gallons in. Especially when driving cross country, I liked to assure that extra range.
Most of the time I've just been refueling when my car tells me to. I think I will stop doing that and refuel much earlier, thank you! As for horror stories, my old car had a problem where refueling could take up to 30 minutes because I think there was a blockage or something in the pipe, and the gasoline would quickly rise up and trigger the automatic shutoff valve. I had to feather the pump and fill the tank agonizingly slowly until the tank was full. AND ON TOP OF THAT, THE FUEL GAUGE WAS BROKEN. It was a complete nightmare to deal with, and when the transmission eventually went out I was relieved to be rid of that problem, despite how much I liked that car.
@@toby7291 If you can't recharge your electric car during a power outage, maybe you'll hear the old saying from the early horseless carriage era, "Get a horse".
I learnt that the hard way - after I got stranded shortly after leaving the gas station on two occasions. It turned out, that my '06 Charger RT was a part of a recall for faulty gas tanks. More specifically - a problem with the vapor recirculation valve caused the car to stall and not be able to start again, if it was overfilled.
in hot summer day by noon gas starts to evaporate faster by the sunlight.. fuel tank under the gas station stays relatively the same temp or day or year long but when the sun is around gas do evaporate faster than the night when you filling the tank.. its visible to the naked eye..
Mhhh! I've been told, 3 or 4 years ago that, my whole gas tank/Evap, solenoid...etc... needs to be replaced because, the lock ring which holds the sensor/fuel pump/sending unit is made out of metal and, it is no longer tight meaning, it is rotten. Compared to older models, it appears that this ring is molded to the tank, not like the good old days that required a hammer and flat head screwdriver, to spin that ring off. I was a mechanic until early 90's. A lot of "stuff" changed and it infuriate me. Can't rebuild nothing in nowadays. Just replace and throw away the core. By the way, my vehicle is a 2010 Silverado. I'll change the fuel filler cap first but, it seems to be available at the car dealer ONLY. "Sailor coarse language".
"Topping-off" gasoline when fuel is a few cents cheaper can damage that evap system. The evap canister can cost $600 or more to replace. The check engine light will come on and the car will not pass emission testing. Listen to Scotty and just don't do it. Don't ask me how I know this. 🙄
There is a reason why when Stellantis is or whatever their name is this week, has this standard for 200,000 mile testing. Keep the tank between 1/4 and 3/4 full. Guess they don't like changing fuel pumps and evaporator canisters?
@@davidgadgetman7753 FCA test driver 2018 out of Auburn Hills. 350 miles per day, 2 shifts x 7 days +4900 per week. Run it till 200K miles and then dismantle, examine and scrap it. The Fiat and Alpha were not included in that testing. Funny thing with proper maintenance a Compass made it to 200,000 and everything still worked.
The problem, Mr. Kilmer, is many gas stations have aging nozzles and/or our vehicles have an aging evap system, and the nozzle shuts off prematurely. I can think of many instances where I've been able to pump several *gallons* of gas after continuing past the first nozzle shut-off (often re-starting the nozzle many times), and at least one instance where I took the nozzle shutoff as "done" and almost ran out of gas on the way home despite having more than enough gas capacity to make the trip, had the tank actually been full. I *always* try to get another slow "snort" of gas in, unless I am completely unconcerned with having a full tank. Perhaps in a future video, you can explain why some older cars seem to trip the gas nozzle prematurely. My 1990's Civic seems to be especially prone to that, whereas my mid 2000's Caravans less so.
I ALWAYS Top off the tank before a long trip, I don’t like running down to empty or when the fuel light comes on and don’t have a problem with sediment or water in our Yaris. The only thing likely to prevent me topping off is the need for funds …. It gets up past 40c here in summer and so topping up for just around town is not so sensible as when you park a black Yaris in the sun and it overflows while you shop … fuel expands most when in your fuel tank in the heat … best not keep it in the car with you if you can help it ….
I remember two brands of older cars: Honda's and Chryslers that when gas was low and the car was in an incline it had a hard time starting. No major issues when on a level surface It had to do with the design of the fuel pump. Also fuel lubricates the pump and cools it too.

I overfilled my 07 Spectra, now it spits gas out unless l fill up as slowly as possible.
Not sure what part to replace.

Love all your videos, but I REALLY like these historical educational ones!
agree!
I learned alot watching this, well done Scotty and God bless :)
Good afternoon,Mr.Kilmer! It is so good to see your program on RUclips. I wanted to thank you,for program today,about Not over filling your gas tank,and to have at least,a quarter of tank of gas in your car.I hope you're having a good week- end,and I wanted to wish you,a Happy Fourth of July Mr.Kilmer. Sincerrly,Nancy Sanders,MO.
Mr Kilmer.....ugh, oh..... don't let it go to your head, Scotty.....just keep the video s coming!!
They used to have the glass canisters with the gas pumps showing in the old days to ALSO show that you were not getting ripped off. You could actually SEE how much gas was going into your tank and did not have to blindly 'trust' the pump meters like we do today (or that the government stickers are legit and accurate for when they are calibrated).
You can probably tell if you are getting ripped off by looking at your fuel indicator
.....you young pups forget the real claim to fame of the old glass canister pumps.....they worked thru power outages....you filled canister by manually pumping gas up into canister and it gravity fed into vehicle....
Realistically, if your mileage suddenly drops, you know you got ripped off at the last station....
This format of video ? From Scotty ? This is a dream come true ! Your narration and diction is on point and your level of knowledge doesn't dissapoint.
...... that's some weird dreams, brother!.....Scotty without waving hands?!?..... who needs that?!?!!!....
Good Info As Always Scotty
True Story. > Waiting at the bank to cash my check years ago and across the street a tanker truck was filling the tanks while i was i line. Was looking over at the gas station and a Geyser of gas shot up from the stations venting system. I was like uhh hope nobody is smoking as this could get ugly. Got my check cash and high tailed it outta there pronto.
I was not gonna be a fireball victim that day hahaha
I’ve seen on your show where you said . don’t overfill or top off your gas tank. One thing you didn’t say inn this video was that overfilling or topping of can make your service engine soon light come on. Well I’ve been topping my 2003 ford E250 off for the past two years . Never had a problem. Then about a month ago the service engine soon light came on. Had it checked and the guy at Winchester auto parts checked it and couldn’t tell me what the problem was. So he cleared the code. It stayed off for another couple of fill ups. Still topping it off. Then it came back on. Well following your advice on another video, saying not to ever top it off or a service engine soon light would come on so my landlord mechanic cleared the code, and I haven’t topped it off cents it’s been about a month now, and no light comes on, so I want to. Thank you for your great advice because I probably would’ve never figured out what it was. Thank you for your great advice. Keep on giving that great advice out. I appreciate it and so many other people you do a great job. Keep it up Godspeed.
Thank you for 30 years I’ve always. Rounded up Now. Because of you’re very sensible explanation. I will stop this practice
I didn't know about the info on topping off the car. Good info !
Thank you for these videos, Scotty! I really appreciate the education.
You're down right "invaluable!"
I had an 07 Focus....i went through 4 or 5 fuel pressure regulators...found out it was because i over-filled the fuel tank...i stopped that & never had another issue
Another reason not to let your fuel get below 1/4 is for condensation. Especially in Humid environments like we have here along the Gulf Coast.
Another excellent documentary presented by Scotty.
Although I was aware of most of the points covered here, I enjoyed watching it presented in a video. And being of the old school variety, I will admit to being unaware of the damage overfilling a tank can cause to the evaporative recapture system.
This guy is a gem love this channel so watch damn near watch at least 1 video daily since we all love learning about cars
I’m loving these videos Scotty! Learned new things yet again. I’m amazed.
Yes, my yukon stopped working after overfilling the tank. Stopped several times and i kept pushing the pedal until it worked. Thank you
Wonderful content. Best mechanic/educator on YT hands down. 👏👏👍👍
For me (from doing this stuff) a 1/4 tank marker is always Empty. This was beat into my head when they 1st started to put the pumps in the tanks. When you have to drop the tank to change the pump and it always came in with a "near full" tank of gas in it. Ultra Heavy, Hard to syphon/pump out, pretty much guaranteed to get a nice stinky Gas Bath doing it. Yep, 1/4 tank and I always look for a gas station.
Outstanding coverage of fuel system for any layman...well done Scotty! THX
I was a transmission builder (we and the electronics guys are the highest paid individuals of any full-service repair shop) and one of the rules with the pump in an automatic transmission is if it can move the vehicle, the transmission has enough fluid in it to keep from burning up the pump. Same with a fuel pump. If it can run the engine, it is getting enough fuel run thru it to stay cool and lubricated. Simple as that. Now, consider never letting the tank run lower than 1/4 full. Every time you fill up, you are only replacing 3/4 of the fluid in the tank at the most. The rest is stale, and over time, this could possibly cause running problems.
As a fuel tank driver here in NJ I can attest to the tanks temperature. The only thing that changes with hot or cold temperatures is the vapor in the tanks. With cold temps I deal with more air pressure in the tanks.
Back in the day, I used to almost overfill gas tank everytime which is why it also destroyed the fuel cap.
Lesson learned hard way 😂😂
I have a 87 Bronco 2 my engine would shut off while driving down the road, I replaced my original gas cap with a new one that fixed it no more engine cutting off while driving. A scary situation if you are on the highway.
Wow, that's crazy
Glory to God nothing bad happened! God Bless in Jesus Christ Name Amen.
Dr. Scotty, the automotive professor. 👨🏫
You can say and be right about not topping the gas tank I still did it, only the time I had to go over the Andes mountains. A five hour trip end being a 22+ hours trip finding alternative routes and being stuck in the road due to the snow. At the end of the day I was worrying about running out of gas but make it to my destination with less than a 1/4 of a tank of gas. On a 2013 Mazda CX-5.
Great job Scottie , your mechanics advise videos are the best.Keep the good work (please) , we will follow you there.
I drive a plugin hybrid and it’s so fuel efficient I actually don’t fill it up the whole way. No problem with topping it off here. I’m so glad I picked it over an electric car. I may go fully EV in 15 years or so (or 20, knowing Toyota).
Scotty - you're always educational! And I enjoy these vids. For the future - could you cover something like EMPs. How it effects the cars and if there are any that would hold up better if exposed to an EMP.
Love ur channel scotty... u r a blessing to society
Apart from this small point, the video and the explanation are simply excellent.
Wow learned something new! Thank you Sir ! 😊👍
Too bad that lots of cars do not even have external fuel filters anymore .
Some have just screens in the fuel tank .
yes they do, in the engine bay before it gets to the injectors. all cars have a fuel filter.
If you can find the filter under the car or hood on a 2001 thru 2005 Civic let me know because I only ever have seen the filter sock on the fuel pump inside the fuel tank, And never had one go out yet even with two cars with over 300,000 miles, the only reason I know this is because I remove the rear passenger seat and access cover then the fuel pump from the car so I could see if any crap was floating around in the tank, but NO it was as clean as the day it was made, But if course Honda uses HIGH Quality DENSO PUMPS.
@@raymondreiff8170 that’s good to know! I have a ‘16 Civic - fuel system seems to be doing fine, but still planning on replacing the fuel filter at 150k miles.
@@raymondreiff8170 some cars like my Mazda 3 had a filter that was for life gid knows how it re cleaned it self.
@@carlovanrijk4039 my current vehicle has 4 filters. One life time filter in both fuel tanks, only replaced if the pump goes out. Then a 10ppm fuel filter/ water separator and 2ppm main fuel filter before it goes into the high pressure pump. The high pressure section runs at 24000psi. Yes 24 thousand psi.
Is this just for newer cars?I've been doing everything that Scotty says not to do on my '98 Cavalier and it still runs great.
me too with my '05 Jeep Wrangler. I run it right down until the fuel light comes on then some more, then fill right up with fuel squeezing in as much as possible. and it doesn't have a fuel filter. 200k miles and still going strong with same old fuel pump and charcoal cannister.
@@bonza167 it has a fuel filter!
@@cyrusmoser1090 only the one attached to the fuel pump afaik. Gotta take out the tank and pump to access it. If there's another let me know
Well I had to replace that EVAP canister on my 2000 Grand Am and my mechanic even told me not to do that but I still get more gas by continuing to fill it up. So I'm not sure, Scotty says you don't see any significant reasons to doing that but I can get up to half a gallon by doing that and really I've only been doing that because of the crazy fuel prices, but maybe its not a good thing if I'm sending fuel back to the pump. Newer cars have more range due to fuel efficiency and larger tanks so I'm looking to get a Honda Civic or Accord in the future.
Anecdotal evidence
Before I got my F150 I had a 2011 GMC Sierra. I always topped it off. That is, until I had to replace an evaporator purge valve. The truck started extremely rough and I eventually got a check engine light. Thank goodness it was an easy fix.
Thank you so much Scotty for sharing your invaluable information, highly appreciate it, keep it up the outstanding job.
You don’t understand. My OCD requires that I round off the dollars at the pump. 😆
round off at a lower number ??
I round up the gallon 😂
.....hope the same OCD makes you amply pay your repair guy.....lol
I really needed to see this Scotty. I always top off and round to the next dollar. I definitely won’t be doing this anymore. Thank you.
Another informative vid that explains theory really simple! Thank you Scotty!
I bought a 79 Ford Econoline van that had been sitting for about two years but it ran very good and I had it for a while, before I let the gas hand go to the E . It sucked up trash out of the tank and never ran right again.
I wish you had this video six months ago i used to top off fuel and sure enough the carbon filter crapped out.
Thank you for all of your great videos! They help teach us a lot 😊
Solid Video Simulation. Love the concluding background song. Scotty is upgrading the style !!!
Please take Scotty advice. I had a 2003 Elantra as my first car that the previous owner jacked up the system. I dealt with the clicking issue until I fixed it myself. The charcoal canister was bad, and allowed charcoal to enter into the vapor lines in such. I replaced it and cleaned out the lines for a temporary fix. Because the issue was so bad, it got further into the fuel tank. I had a mechanic clean out the fuel lines and the issue was no more
I recently purchased my 2011 Corolla from someone who always overfilled to "save time and trouble". I went over his repair receipts and he had to replace the vapor canister twice from problems such as leaking.
Excellent explanation of the evap system to share with my new driver grandson instead of just “don’t do that!”.
Scotty, most cars from 2008 on have the filter built into the fuel pump assembly not easy to get to to change previous models years the filter was in line towards the engine bay! I think on a lot of the Denso pumps They just have a fuel strainer on the end
I’ve been in the habit of topping of the gas tank since 1972. I heard vehicles from 1996 and newer that over filling is a bad idea. I learned this too late. My current 2006 pickup, I’ve owned since new, with 135K on the odometer. The past few years it’s gradually getting worse at accepting gas into the tank. I got to the point where it would only accept 3.5 gallons (on empty) very slowly, and pump would not fuel any further. I paid mechanic about $1300. (To repair). The fuel goes in very slowly, but I can fill it. I wish I could have heard this sooner. When I got my truck back from the mechanic, (a week ago), I filled up in the normal way, by topping off the tank, so it is absolutely full. I realize my conduct caused this problem (now).
well done Mr. Kilmer I have been over filling my Camaro for............... well, a long time. I don't needa tell you how much un those fuel pumps are to replace. I knew too empty was less then ideal (for the reasons you stated) but never knew too full was even a thing.
R.B.G.
Manors Creep
I used to top off all the time with my vehicles and never had a problem. I began doing it with my new Volkswagen atlas. The check engine light came on and the dealer had to replace the charcoal evap canister because it sucked in fuel. Luckily the warranty covered it but since then I’ve stopped that bad habit.
Love your channel Scotty you're a gem!
Your videos are great and very educational Scotty!
I worked for Toyota for years, and we have had to change several charcoal canisters due to gas tanks being overfilled. Scotty is right, the charcoal was saturated with liquid gas where it should only handle fumes. $500-$700 repair because of squeeze in a few extra clicks.
Well it looks like I just learn so much important information about the fuel system. Always love learning!
Scotty stepping up his presentation! GREAT JOB
Mr. KILMER'S level of INTELLIGENCE is absolutely, STAGGERING! I thought that I was fortunate enough, to have some
"smarts"; however, compared to his intellect, I have come to the conclusion that I'm indeed, a "bone head"! Your
millions of subscribers LOVE you, SCOTTY. THANK YOU FOR HELPING US!! ❤❤❤❤ Roland Singh, Canada 🇨🇦
Hear hear Roland! You are spot on!
4:48 that one guy backing up to the pump 😅
I read in my old car’s (15 Hyundai Veloster Turbo) manual to never pump further after the pump “clicks” so I never have topped off, but I always wondered why not to-my mother did though (I will have to teach my mother this).
My 1970 Duster showed 1/4 full when it was empty. So I learned to keep it above 1/4 of a tank or I was hoofing it.
My 79 Dodge pickup was the same way. I used to make the trip from Great Lakes Navy base to home near DC a couple times while up there. Ran out of gas twice in the same exact place in Indiana on US-30. Slow learner..... Why US 30? Ohio State Patrol would give you a ticket for 1 mile over the speed limit on the Ohio Turnpike. I would follow the trucks on US-30, they would run 90mph and never see a cop.
Some wise information Scotty, thank you. 😎👍
Changing the fuel filters is often more involved than it used to be. You have to pull seats and get into the gas tank in a lot of cases. Or drop the whole tank.
I haven't encountered any cars with in tank fuel filters... just the sock on the pump...
Honda and Toyota both have one-way valving systems to stop liquid back feed to happen from the tank to the vapor system. Along with bubble top tanks designed to have a 1 liter air bubble at the top of the tank you can not fill with fuel. These have been in use for over 8 years.
Back in the 70's I was maintaining and driving a fleet of Dodge B300 passenger vans. They had steel tanks which could hold 26 gallons, but because of a bad filler design, you couldn't easily get more than 22 gallons into those tanks. It was bad enough that Dodge revised their "specifications" to a 22 gallon tank. When I was patient and let the tank burp, I could get the extra 4 gallons in. Especially when driving cross country, I liked to assure that extra range.
Most of the time I've just been refueling when my car tells me to. I think I will stop doing that and refuel much earlier, thank you!
As for horror stories, my old car had a problem where refueling could take up to 30 minutes because I think there was a blockage or something in the pipe, and the gasoline would quickly rise up and trigger the automatic shutoff valve. I had to feather the pump and fill the tank agonizingly slowly until the tank was full. AND ON TOP OF THAT, THE FUEL GAUGE WAS BROKEN. It was a complete nightmare to deal with, and when the transmission eventually went out I was relieved to be rid of that problem, despite how much I liked that car.
Idk what my generation would do without you!
With the frequent power outages in California, maybe the old glass cylinder pumps might come back into use. 😄😄😄
I heard they are getting rid of gas in California. 😂
@@toby7291 If you can't recharge your electric car during a power outage, maybe you'll hear the old saying from the early horseless carriage era, "Get a horse".
@@toby7291 The Governor's a gas bag!
The fuel filter in most modern cars are inside the fuel tank as part of the fuel pump assembly.
Yep haven't seen an inline filter in cars for years
I learnt that the hard way - after I got stranded shortly after leaving the gas station on two occasions. It turned out, that my '06 Charger RT was a part of a recall for faulty gas tanks. More specifically - a problem with the vapor recirculation valve caused the car to stall and not be able to start again, if it was overfilled.
Wow Scotty I was one of the people you spoke about. I use to make sure to fill up in the morning especially on hot days.
in hot summer day by noon gas starts to evaporate faster by the sunlight.. fuel tank under the gas station stays relatively the same temp or day or year long but when the sun is around gas do evaporate faster than the night when you filling the tank.. its visible to the naked eye..
Mhhh! I've been told, 3 or 4 years ago that, my whole gas tank/Evap, solenoid...etc... needs to be replaced because, the lock ring which holds the sensor/fuel pump/sending unit is made out of metal and, it is no longer tight meaning, it is rotten. Compared to older models, it appears that this ring is molded to the tank, not like the good old days that required a hammer and flat head screwdriver, to spin that ring off. I was a mechanic until early 90's. A lot of "stuff" changed and it infuriate me. Can't rebuild nothing in nowadays. Just replace and throw away the core. By the way, my vehicle is a 2010 Silverado. I'll change the fuel filler cap first but, it seems to be available at the car dealer ONLY. "Sailor coarse language".
"Topping-off" gasoline when fuel is a few cents cheaper can damage that evap system. The evap canister can cost $600 or more to replace. The check engine light will come on and the car will not pass emission testing. Listen to Scotty and just don't do it. Don't ask me how I know this. 🙄
There is a reason why when Stellantis is or whatever their name is this week, has this standard for 200,000 mile testing. Keep the tank between 1/4 and 3/4 full.
Guess they don't like changing fuel pumps and evaporator canisters?
how do you know this?
@@davidgadgetman7753 FCA test driver 2018 out of Auburn Hills. 350 miles per day, 2 shifts x 7 days +4900 per week. Run it till 200K miles and then dismantle, examine and scrap it. The Fiat and Alpha were not included in that testing. Funny thing with proper maintenance a Compass made it to 200,000 and everything still worked.
The problem, Mr. Kilmer, is many gas stations have aging nozzles and/or our vehicles have an aging evap system, and the nozzle shuts off prematurely. I can think of many instances where I've been able to pump several *gallons* of gas after continuing past the first nozzle shut-off (often re-starting the nozzle many times), and at least one instance where I took the nozzle shutoff as "done" and almost ran out of gas on the way home despite having more than enough gas capacity to make the trip, had the tank actually been full. I *always* try to get another slow "snort" of gas in, unless I am completely unconcerned with having a full tank.
Perhaps in a future video, you can explain why some older cars seem to trip the gas nozzle prematurely. My 1990's Civic seems to be especially prone to that, whereas my mid 2000's Caravans less so.
I ALWAYS Top off the tank before a long trip, I don’t like running down to empty or when the fuel light comes on and don’t have a problem with sediment or water in our Yaris. The only thing likely to prevent me topping off is the need for funds …. It gets up past 40c here in summer and so topping up for just around town is not so sensible as when you park a black Yaris in the sun and it overflows while you shop … fuel expands most when in your fuel tank in the heat … best not keep it in the car with you if you can help it ….
Well explained, I am of the old School and have certainly learnt something new. Thank You.
I remember two brands of older cars: Honda's and Chryslers that when gas was low and the car was in an incline it had a hard time starting. No major issues when on a level surface It had to do with the design of the fuel pump. Also fuel lubricates the pump and cools it too.
