After I top off my truck I pump the bed full of gas too. Never had any problems.
+Joe Smith I'll bet you don't really do that.
wow poker genius here
you bet on lots of things? i would if i were that smart
🤣🤣🤣🤣🤣
Joe Smith Haha. That's great 😁
Joe Smith 😂😂😂
Well, this is news to me. I have a 2008 Toyota Highlander with 165,000 miles, and every time I have filled it up I have added at least a gallon and a half more after it has clicked off. I keep filling it very slowly until it fills all the way up the neck and haven’t had any problems so far. I guess I’m very fortunate.
Same with my cars for years no issues, however I had a friend mess up his brand new Audi A4 years ago when he topped it off on his first fill and the gas leveler broke off inside the tank giving wrong readouts of fuel level. I guess German cars mainly get issues with doing that?
I accidentally it to my Hyundai gls accent I accidentally filled but I filled to the point where gas was leaking out of the tank so if anyone if I just messed my car or not please let me know
Mctony Jr it's probably ok. I think if you do it every time it might cause a problem. Like I mentioned I fill it all the way but not to the very top so as not go into the vent holes at the top.
There is a contradiction here, either the nozzle collects the excess fuel or it spills on the ground, not both.
Here in the UK the nozzles only recover fuel vapour, not liquid as far as I understand it. I tend to top off to avoid leaving airspace in the tank, where condensation of water could happen on a cold day/night
The nozzle has a back-pressure trip that causes the flow to stop when it sees it. It does not know that the tank is full - one of my cars would trip the nozzle even when empty, and I had to find the 'sweet spot' so it would fill the tank. The 'back flow' is the air trapped in the tank that pushes the fuel in the filler back up to relieve the internal pressure, consequently overflowing the filler. (like a baby's burp). Topping is not a problem if you are going to drive any distance, as 20-30 miles will use up a gallon or so anyway.
I always pull out!
Nice!
That sucks. My car cant get pregnant so I NEVER pull out😎
I get it close then pull it out and spray it on the truck to the round off the price.
firefeem Now you just need a lighter
That's also how porn stars fill up their vehicles.
I usually dont put the nozzle in all the way, after it clicks i pull it out and pour it in until the fuel is at the edge and tada. I have a full full tank. Never an issue
Some older cars you CAN top-off: I can actually squeeze another $3-5 worth of gas into a 2000 Toyota Sienna simply because the shutoff point is so early.
But newer cars are very sensitive; my Mitsubishi Outlander clicks, it's topped off. No more no less.
I tried pumping my mother's 2009 Mercedes C250 once; the front of my jacket stunk of gas when I got back (my sister though the car was spewing gas lol). Lesson learned.
Great Point Trades46!! Thank you for the comments! I've noticed that about the older Sienna's too. I don't know why the shut off happens so early in that model.
The warning should be "Don't overfill" not top off. I can see where some vehicles could have an issue with an overfilled tank if fuel got into the evap system through the canister purge system but some vehicles have fuel tanks that won't even allow a full tank without 'topping off" the tank as you fill it. I have four pickup trucks, on each one if I wait a few seconds after the pump shuts off, I can get another few gallons in the tank, each time. If I let it shut off by itself, I'll end up with about 7/8 of a tank at best. I've taken my time and gotten as much as 10 more gallons in the tank. That's a lot of fuel when your running long distances where there may not be another filling station when you need it.
Excellent points! Thanks for contributing to the conversation!
Yes agree with you 💯 percent, depends on the individual vehicle, also its how you let the fuel in I've always done it very carefully on my diesels and never had a problem in any vehicle, Ihave a strong hunch this is a gasoline issue pumped in by heavy handed drivers at full steam on the gas pump...
I have 'topped' my gas tank for years without any problems whatsoever. I've done so with several of my cars and with pick ups including my 2013 pick-up which I bought new. Never once a problem. Most of my vehicles were used and old. They had a verity of mechanical problems now and again but they had nothing to do with topping off the gas tank. And, I have never had trouble with a car or truck passing inspection! And I've never had gas leak out of the fuel cap. If this is happen to you - perhaps it's time for a new fuel cap.
Not sure if this applies to all autos but i get 500 miles when fuel is to the top vs 420 when i just stop when the handle clicks. I like that extra 80 miles!
This video is generally true, but I have often encountered gas pumps that pump so rapidly that it will shut off way too soon. Then you have to keep restarting the pump while trying to hold it in such a way that it pumps more slowly until the tank if full. some times partially withdrawing the nozzle helps but is a little risky.
Well said, never top off mine (always put the nozzle away after hearing the "click") 😎👍🏻
If you doubt this video about overfilling causing issues, leave your fuel door open, those without sensors on the door will have issues detected by evap system leaks out the fuel door, likewise as stated in video, overfilling will also interfere with the sensors.
Excellent point! I hadn't thought of that!
Topping off causes any residual gasoline varnish/dust/road dirt etc to move up to the Evap purge valve making it stick open and engine ends up with evap leak/valve codes. Driving around normally can also do this as fuel does move around in the tank.
Take Evap valve off, use some non aggressive brake cleaner and clear codes. Done.
Dan R Nice! Didn't know that! Thanks for contributing to the conversation!
I top off, drive and run the A/C for about 20 minutes
Gas tank no longer topped off as engine consumes the extra.
Doing this for 18 years.
If you want a little free fuel,set an amount,full until the pump stops,then hold the handle,and you will notice that a little more fuel will flow out of the nozzle!
I agree in theory but the difference is what you consider "topping off". Adding a bit more to round off the price is not a problem at all. What you describe sounds more like overflowing the tank to the point gas pours out of the fill port. If you are overflowing the tank you will have the problems described, but not from simply adding another click or two of the nozzle.
I know that I cannot pump anymore into my F150 after it stops. If I squeeze that handle even one more time, fuel will spill out onto the ground. When the pump stops, it's full.
I have more miles when I top it off then when I don’t which I’ve noticed. Maybe the nozzle is incorrectly stopping before there’s a full tank of gas. Because everytime I don’t top it off I have like 370 or 380 miles left then when I top it off it’s 420 something.
I love it when he says if the gas spills on the ground that's bad for the environment all these people out here smoking damn cigarettes
A very useful advise. I learned my lesson not to top off, by replacing 2 charcoal canister and 2 leak detection pump on a BMW X3. I always used to go for the extra .50 to have a whole dollar amount not knowing i was harming the evaporative system in the vehicle. When you hear that click stop what ever the $$ is. New vehicles are so complex now a days.
That's absolutely correct, my friend! Thanks for sharing your experience!
You should also never let your gas get below 1/4 tank.... most cars have an in-tank fuel pump and the pump overheats and wears out much sooner if there's not enough liquid in the tank to keep it cooled off. I had a girlfriend that replaced 3 fuel pumps in 2 years because she would always drive around with hardly any gas in the tank.
The fuel is stored underground at the gas station, and is at a cooler temp. During the summer months, the fuel warms up once it gets in the autos tank and starts to expand with the warmer outside temp. If the tank is too full the fuel travels to the evaporative system, which is designed to handle vapors, not liquid. The car manufacturers have already designed the tank for expansion. If you drive a couple of miles after it is filled up, the level starts dropping immediately.
So the only time it may be a problem is on very warm days, where the car is not driven after being topped off.
I have only been topping off all my cars for 60 years.
Very helpful info that I never knew before. You may have very well saved me hundreds of dollars in future fill ups. Thank you sir.
Thanks for the comment SilentHill401! I hope this helps and I hope you find my other videos helpful too!
SilentHill401 another dummy
Damn I thought I was going to be a rebel and here I am just one of the crowd. GM was once sued because they sold optional large gas tanks that were actually the same size as the standard small ones, weird eh. The filler neck in the small tank was about 8 inches long and in the large tank (same outside dimensions) it was only 3 or 4 inches allowing you to put more full in the tank ( before it would foam and click off ). topping off only fills a little more of the tank and while it's not a good idea to do this normally, if you are going to be driving for a while and the gas is cheap it's a great idea.And that is "the rest of the story"
Bob Moynes a link to that sue for large gas tank story?
@@xr6turbo324 this is a reallly late reply as I just rediscovered this email. It could be an urban legend but I have personally pulled the spout out of several tanks and found there to be two sizes. This was in the 73 to87 range any that I observed 73 to 78.
Biggest problem is with diesels. Over 60% of the fuel drawn from the tank is returned after a trip around the hot engine bay. The fuel expands and could block the breathers, or overflow through the cap.
Interesting that he is saying don’t top off but really has not hit on why it is a problem. All modern cars have a vapour recovery system that relies on a filter and relays that capture any gas vapour that would normally escape from the tank while you’re filling it. The way the system works relies on the filler tube to be small enough so that all of the fuel that goes in pushes the vapours in the tank out through a Charcoal cannister that’s located above the tank. In essence the fill tube has a liquid seal as the fuel is poured into it and does not allow any gas vapour to backflow out of that Fill tube. If you overfill your tank you will push not only vapours but also liquid gasoline into the vapour recovery system. So why should you care. If in fact you do get liquid into your cannister it will cause the fuel fill system to back up. In other words the gas won’t go into the tank because there’s nowhere for the vapours to escape. I had this happen to me and the dealer wanted $450 to repair it.And I can tell you if you were living in a place that’s very cold and it takes you 30 minutes to get the fuel into your vehicle because your vapour recovery system is damaged you will not be happy. Manufacturers were forced to install these systems to prevent hydrocarbons from escaping into the atmosphere. When you start your car The vapours that were captured will be pulled into the engine and burned as fuel. So to some extent you will be getting fuel that normally goes up into the air. However this amount of fuel is very small and would never pay for the additional cost of the system to be installed in the first place. So it is all about the environment. But overfilling can damage your fuel vapour recovery system And make it very difficult to get fuel into your tank. If you do have this happen the only way to get fuel in is to literally trickle it in at a very low rate.
yes you are right
i see a lot of gas attendents do that
and also when they close the cap the click
it 40 times
i always top it off.. never had a problem.
Fun fact: (at least in some places in America) this warning is present on the gas handle
It's a back pressure thing that shuts off the nozzle. butr yes, it's not good to overfill as it will flood the charcoal canniister and eventually ruin it.
And after reading the comments people have no clue how these pumps work the little hole or hopes on the nozzle yeah that's the vapor recovery it pulls a vaccum yes , will it take fluids in to an extent but it has a built in valve once the vapor density changes it closes the valve and spits the gas it sucked up back into the tank on your car
My friend topped his tank off. He's doing Life + 20.....
That's just silly, the federal tank top off statute indicates that, "one shall not be sentenced to more than 10 years in federal prison." So, your friend could only do a 10 year max.
HowToCarGuy He topped off his tank on the way to rob a Brinks truck....
Did he top off the Brinks truck too? Haha
Wha ???
I'm a fuel engineer and I won't go as far as to say you are wrong on this subject, it is however outdated as modern day pumps have vapour recovery style nozzles which wouldn't let the fuel sit inside the nozzle. you also missed one key move when mimicking the "topping off" in that most people edge the pump out of the car a few inches before doing it. again, impossible to leave fuel in the nozzle this way.
Well, that's a new one on me, however, say you are pumping the gas, and, with my vehicle at fill up, it's around 56 dollars. If it stops at say, 55.80, and, just for shits & giggles, I decide to round it at 56.00. Would just that extra 20 cents make that much of a difference? I know back in the 70s, I had a 1974 Chevrolet Nova. All that happened after topping off, esp. in the Summertime, the gas dribbled out of the tank, as in expansion of gas, as I knew that would happen. But, today, 20 cents more to round it, can make a difference?
Your right but.. When you get to A quarter tank that's the last notch B4 empty for those who can't understand lol. You should not have less than that ever, it is the one thing that cools your fuel pump and if ever you have had to replace the thing you know what it costs!. If not the job takes A mechanic about 20mins to fix but costs almost $750.00 plus labor so do yourself A favor and keep more than A 1/4 tank in it at all times!!. This goes for newer cars as well
i always top off and i don't find any problems.. gas is gonna go back up, yes that always happens but that is why you go manual on the pump once it already stopped on auto and its not really topped up at 1st.. if you give it about a minute or two or maybe try to rock your car, you will see the gas go down.. my point is i always top off/up and i haven't had any issues..
Dude you're way off. Topping off means to fill it to the very top rim of the spout. They're saying don't do that.
Best advice: As long as the gasoline is not overflowing out the fill nozzle, it should be okay. I've never, even back in the day, had a problem. Second part of that advice: Take internet advice with a healthy amount of skepticism.
I ALWAYS take internet advice with a healthy amount of skepticism - like, this one time, I met an African Princess who promised me $9,000,000.00 USD because she was about in get $50,000,000,000.00 USD from the death of her righ husband. All I needed to do was send her $5,000.00 USD and she would send the money. So, I sent the 5k and I am expecting my 9MIL ANY DAY NOW! So there!
And you know everything there ever was that was knowable, right? What do a book of matches, a dime, and a screwdriver have in common, oh, great sarcastic one?
I accidentally did it once, will that be a serious problem if I just did it once?
i top off all the time. when i top off i leave the nozzle on the ege.
EC Clockwork that's true topping off
I did top off my w203 today and guess what happened, it is dripping from the fuel pump, and i can't get a mechanic to help me till morning, so to avoid any accident I took the car out, jacked it and put a bottle on the pump to collect the fuel, i will keep an eye on it till it stops, if it is about getting that 60L out i have no other option than burning my can and my home. what a very bad night for me
LOL I was always told to make it click 3 times.... guess i am not doing that anymore. Thanks for the tip.
You're welcome! I'm so glad this was helpful for you!!
HowToCarGuy if you have done that a few times before is that a problem? I won't do that anymore but I'm just wondering if the damage is all ready done.
I have NEVER had a problem of any sort from topping off. The pumps have a vapor recovery system that it probably affects though. This is all pushed by the same environmentalists that think electric cars don't pollute.
Thanks a lot man but ... Why u no post this video earlier ... Every time I fill up I all always top off and lately, no wonder my system only shows 360 mpg instead of 405 anymore ... Lesson got.
Just hoping it will be back to normal if I stop topping off ... Sigh
Kuku liu Thanks for the comment! You should see your system return to normal very quickly!! Don't worry about it - I used to top off with EVERY tank!
Brock
360MPG! What car are you DRIVING!
HowToCarGuy oh wow, huh I didn't expect that. so you're saying if someone stops doing that even if it was on a rare occasion then there will be no problem.
That 'click' , as you put it' is not the car saying anything what so ever. It's just the pump handle recognizing that the gasoline is bubbling up the filler hose. My van has a 36 gallon tank. The nozzles shut off when it gets to about 26-27 gallons in the tank. I have to pump very slowly to fill it all the way up.
The nozzles do not suck gas out of an over filled car and put it back into the storage tank.
Maybe... just maybe that happened 30 or so years ago when vapor recovery was in it's infancy.
The pumps do not suck gas back.
makes sence..
The fuel nozzle determines when the car is full, not the car.
Maybe you want to make a video where you explain why not to run your car empty.
Mr. 2cents. Yeah and another saying how you shouldn't fill your gasoline car with diesel or vice-versa
How do you know when to stop then?
cheers but I can't afford to fill up half a tank never mind a full one!
People think a gas station will fill your tank up to the max = more $ for them when you pump more your tank already hit max and it just goes back to the station more $ for them why would a gas station not full ur car up to max and lose $ they could have gotten
It happens every time I fill when you first start to pump it always shuts off first then you have to pull the handle again. So should I not fill my car? No. I have also owned cars that you had to put the nozzle in at a certain angle to get it to fill. So the thing is to know your car. My car I pull the handle it fills up and clicks off I normally just pull it one time and it clicks off in about a second or two this would be similar to rounding up you cents. I don't think there is a problem with this at all. Now I have seen people shake there car keep pulling the handle to get as much gas as possible in the tank and filler neck Yes this is not a good thing to do.
Majority of people use credit card. So who cares if the money amount isn’t even!
Some folks are just beyond stupid..😶 knowing how flammable gasoline is,, why would you risk overfilling it until it winds up leaking all over the place? Especially on a hot day....and its a waste of money because you are still paying for the extra gas that spills back out of the side of your car....😶some folks shouldnt be driving a car period.
The reason it says don't top off is that the gas splashes out and is bad for the environment.
Thank you very much for this info.. keep going.
Roro,
Thanks for the comment! I hope you enjoy my other videos too!
The more you know!
Thanks
Absolutely Killerelite354 !!! Hope you find the rest of my videos helpful!
DOES THIS ALSO APPLIES TO A DIESEL CAR??? ANYONE KNOWS? THANKS!
Wow. You are sort of right but not really. A EVAP issue wont make your car run rough. All it will do is trigger a MIL. And gas doesnt get sucked back in the nozzle. If gas registered on the pump it came out the nozzle and into the tank. The car doesnt tell the pump to shut off either. The pump decides to shut off when pressure is no longer coming up the secandary spout inside the pump nozzle.
lol goes back into the nozzle.
I will never top off.
I thought you were going to give me a reason that would dissuade me from topping off my tank......
HaHa, okay now you're getting there! I changed one on a '97 Chrysler Cirrus, nearly had to remove the whole front end to get to it.........
Not sure about that, been doing it for over 34 years in different cars, from carburetor to fuel injected. My current car is 22yrs old, I fill it to the first click, then round it off, about another 50 ml, which isn't much, never had a problem, but in saying that, I won't own a new car, to me they're to expensive and full of shit you don't need, cost a small fortune to service and repair, but thats my opinion.
20 years and I never had any issue
ok so totally bs on putting $.05 to $.10 extra in your tank is going to hurt. topping off and rounding the cents off is two different things. your taking a ant hill and making it Mount Rushmore. just Stop.
I assume that you have heard of the radio show "Car Talk". The Tappet Brothers had a nationally syndicated show that gathered a cult following of car people. "Click and Clack", as they were called, were veteran mechanics who could literally answer ANY question, no matter how complicated, over the phone to help people understand what plagued their vehicle. These guys have seen it all and know, from experience, how to fix anything. I tell you that so you understand the significance of clicking the following link www.cartalk.com/content/why-topping-tank-bad-idea
I can assure you that I will never, ever stop helping people learn what is best for their vehicle. 5 cents here and 10 cents there costs $500.00 to $1000.00 one day because that nickel and dime put in the tank to top it off actually STAYS in the evaporative system for a long time. Next thing you know, another 5 cents or 10 cents is ADDED TO that last time it was "topped" and thus, you're on your way to a shiny new charcoal canister or catalytic converter. So, it's not an anthill OR Mt. Rushmore - it's hundreds of dollars that many hard-working people can't afford. Thank you for your contribution and have a wonderful day. And remember, don't top off that tank :)
Brock
+HowToCarGuy ant hill into Mount Rushmore. thanks
Sorry, might be true in the odd car, all the work cars I fill, not right for those
thanks, i'll remember that
You're welcome The General Lee Thanks for watching!
HowToCarGuy I paid for fourty dollars worth guess it was to much got a 2000 Silverado left the nozzle going I looked back to see when it was done got out then I saw gas pouring from underneath then nothing drove fine is there a overfill on the tank?
Two 20+ year old cars would disagree with this. The presenter completely fails to account for the velocity of the flow of fuel through the nozzle. The faster the flow, the quicker the backflow and shut off. The slower the flow, the less the turbulence, and more fuel filled.
Anybody else saw e85 compatable
I only top off by 30 to 50 cents, because sometimes the fuel pump goes off to fast, and I will leave the gas station with my tank half way full. Is 30 to 50 cents, to much, just to make sure it did not go off too soon
Calvin Mills - At today's prices, you can top off with a few ounces, 10 or 20, of gas!
Thank You ...
Absolutely! Ehab Hassan Mohamed Hassan Let me know if you want to see any other videos to help you.
To be honest with you hundreds and thousands dont really follow this safety procedure..this is more dangerous in hot climate..
Yeah, just stop. It's full. Fill it up again when it's needed to be filled.
So we fill er up yo three quarters
You can fill it up to the top but when the pump stops you should not continue to pump.
I see, but my acura cl sometimes stops about abiut a dollar from any amount what does that mean . Thanks
Ivan Soto Try pulling the nozzle out SLIGHTLY (less than 1/2 inch) and see if that helps.
Ok, yes it did thanks
No, I'm sorry sir. There is more than one factual error here.
+Harvey Smith How many?
NERD'S NO NOTHING ABOUT VEHICLE MAINTENANCE! This guy is too clean to be any kind of mechanic professional!
alex tuck know nothing*
I agree this is bullshit
alex tuck
He isn’t a nerd, his punctuation is too bad to be a nerd.
Good
Rich people problems I can't even get half a tank
Hunter Helms Boo hoo! They have $1 more than me and that's not fair!
People who WORK problems.
Your level of fuel has nothing to do with money
you dont need to be rich to fill your tank
jeff you seem to think broke people will keep their needle in the top half of the gauge if given good advice. that is about as dumb as a box of rocks. maybe you have never been there but for those that have they will spend their money on something needed first and if they have half a tank of gas guess where they are not spending that money.
I've topping off my fuel tank since i got my driving licence (30yrs ago) and i never encountered any single problem... at the matters of fact.. my car can travel further vs the 1st click.
When you want to fill up to the brim.. pls becareful and avoid spilling ... usually third clicks will fill up abt 95 %
I have a 05 corolla with over 300,000 miles on it. I always fill it to the point where it will not take another drop. This car has a 12 gallon tank and 90% of my fill ups are over 14 gallons. When the pumps shuts off I can still get another 2.5 to 3 gallons extra in the tank. At 30 miles to the gallon, this get me an additional 75 to 90 extra miles per tank. The only evaporative system problem I have ever had is a bad fuel cap at 295,000. So your claim is bogus. Im 53 and have done this with every vehicle I have owned.
The real reason cars have the "do not top off" warning is because models with evap cansiters can end up flooded with fuel if you fill right up to the neck as it flows down the evap system breather pipework. This can lead to engine lights and poor running and idle.
You resemble a villain from an Indiana Jones movie. Subbed
On a 98 Ford Ranger been topping the tank off since I bought it in 98 never had a problem and I will continue to do so .
Why your literally paying to pump gas back into the gas station
Not if you hold the nozzle out of the tank and pump it slowly until its topped off
I used the nozzle as a flamethrower one time. I was being robbed while filling up so I pulled the nozzle out, pointed it at the guy with my lighter in front of it and let it rip. He looked like burnt charcoal afterwards.
I really don't believe you, but that would make a great movie scene!
@@SlipKnotRicky His name is “Peter Griffin” obviously kidding lol
What absolute bollocks. The click is NOT the car saying it's full - it's a sensor in the nozzle shutting off the flow of fuel. It's fine to add a little more - you'll use enough fuel in just a mile to account for any expansion of the fuel.
You said bollocks
Mark Fox is totally correct here! the OP's advice is wrong!
Yep, thats an auto shutoff switch inside the fuel nozzle. Theres a small hole for air to flow into, when the air flow stops it basically triggers a switch to shut off the pump.
Mark Fox I agree with your comment, this is 100% correct. The video is wrong in this regard. It is also wrong regarding the pump sucking the fuel back up. I have topped off tanks many times. The only issue I have had is going too far and spilling a small amount and that I agree is wasted gas (and a potential hazard).
Mark Fox I always top off. If I don’t my gas needle won’t be on full. I get three or four bucks more sometimes
DO NOT TOP OFF GASOLINE TANK is for manufacturer's environmental liability and driver and occupants safety and liability. Gasoline tends to expand and cause excess fumes and vapors to build up pressure, so when you have fuel up to the cap you are risking a very dangerous situation as the excess might end up in the EVAP system on new cars and out the cap on older ones, and catch on fire!!! EVAP line is usually located close to the filler cap, by the top of the filler neck. New vehicles have sealed fuel systems and do not have vented gas caps, so gasoline vapor travels through the EVAP system that partially returns vapor back in the engine's combustion chamber and/or vents through the charcoal canister gets cleaned up and vents out into the air. Also it depends how you top it off. If you keep clicking a perfectly functional nozzle, eventually it will stop pumping at the tip of the nozzle, which is usually about 10 inch long, you will still have some room for expansion to reach the EVAP line, but if you pull the nozzle out and you slowly fill fuel all the way to the edge of the filler neck then you are asking for FIRE and/or EXPLOSION since the excess fuel will end up in the charcoal canister! If fuel leaks out of your gas cap on a vehicle with a sealed EVAP system you have to replace the cap immediately since it will set off check engine light the least, or you are driving around with a Molotov cocktail waiting to catch fire!!! Same statement is valid for vented gas caps, except you don't have to replace the cap just do not fill gasoline until it reaches the edge of the filler neck!!!
Thank you for this information. I never knew this. I never top off anyways, so this advice isn't life-changing for me, but it's still interesting to know the possible consequences of filling the gasoline to the filler.
Your reasoning, I can believe.
wait what? you think there are people that hold the nozzle out of the filler pipe and keep dumping gasoline in there? there is a flap door that has to be breached or the gas will splash out on your feet. personally i do not know anyone stupid enough to do that and i know some pretty stupid people. i guess you could get a funnel to hold the flap open but that is a lot of work to add a few pennies of fuel.
Setting aside any clearly visible spillage due to overfilling of the tank, the rest of this is PURE BUNK. The car doesn't signal when the pump should stop, the mechanism inside the _PUMP HANDLE_ does and fuel released after the initial shutoff DOES NOT go back up the hose into the pump. The mechanism inside the handle will NOT allow this to happen - it simply won't allow any more flow when it senses liquid at the outlet of the nozzle. The only two VALID reasons for why topping off MIGHT be a bad idea are 1. Environmental due to spillage and 2., _Possible_ damage to the vehicle's evaporative control system (carbon canister and/or purge valve).
Yeah, Ima go ahead and disagree. At least for me, when I hear the click i pull the nozzle half way out and squeeze gently until i see gas starting to come back up i easily get another gallon this way. On the bike and in the car
Another gallon? I think you need to go back to science class, bud.
777Edub yep, I do too.
Same
I accidentally overfueled my tank tonight. First time ever lol. Will it damage my car or would it run normally?
Great question! I wouldn’t worry about it. You just don’t want to make a regular habit of it.
You know what’s crazy is iv actually never heard of not topping off until today iv done it my whole life and I don’t think it has done anything to my car but I’m glad to know this so next time I fill up i know not to top off
Someone needs to instruct those Oregon gas fillers. They top off on like every car!!!
Or just leave that retarded state
It's not retarded, just archaic gas pumping laws, such a pain to gas up there, don't know how they put up with it.
I spray all over the place when I pull out.
After I top off I also squirt a little over the windows and the bumper to help clean the bugs off.
Works great.
Sometimes I pump a gallon or so into the bin next to the gas pump also because its how I roll.
MyJizz UrEye THAT'S the spirit!!! Love it!
HowToCarGuy I had heard you love it :)
If I can put two extra gallons in the tank after the first click then usually I can drive an extra 80 miles if I'm averaging close to 40 miles per gallon that's a big difference
gas doesn't "come back up into the nozzle." what actually happens is they'll send a gremlin to follow you home. while you're sleeping, the gremlin will drill a hole in your gas tank and drink your gas. by the way. how is spilling fuel on the ground "bad for the environment" specifically? I deliver gas and it's spilled on the ground when we load it at the rack and it's spilled on the ground when we unload it.
Kinda like oil spills. It Came from the ground didn't it?
rabie4x4 Yes, it's sending it back to mother earth for recycling.
Simple solution. If you want to round your fuel tab to the nearest even dollar amount, always use a portable gallon fuel container to pour the excess fuel. ⛽
When, your fuel amount has dropped down after driving for a while, then you can always pour the extra fuel into your tank. Problem solved. Unfortunately, critical thinking and practicality has greatly diminished within our society.
Don’t do this buddy topped his tank off drove a couple miles engine threw a rod hit the ground sparked caught the trail of fuel he was leaking the flames shot up in the tank and the car completely blew never saw the ford again (buddy walked with minor injuries)
And then there's This! Wow! I'm glad he's ok!
This is not for people wet behind the ears. The old days when you used to pull the license plate down to fill the car with Regular topping off is a big problem because you will take a shower in fuel and when it backs up on you and when you take off the gas will go shooting out the back. Also the habit of doing this comes from Gas lines and Even Odd gas day. You really wanted to get every drop in there you possible could.
do not top off if only there for an environmental purpose. the whole EVAP system is not effected untill fuel is literally flowing out of the tank. until then it has no effect on it. and as far as the clicking off signalling the fullness of the tank, though right in theory, it isn't always accurate. if debris, or a small spider makes a web in the EVAP system, it will cause premature 'clicking' (which was a problem in a few Hyundai model years) resulting in underfilling. the click from the pump is only caused by back pressure. just simply filling on an incline can also cause premature filling. finally, the engineers who designed the fuel systems know people would be to tempted to round up to the next increment, so they designed the fuel tanks to create back pressure a little early to allow for a bit of wiggle room.
hope this comment helped shed a little light. :)
Anthony Valentin ohh okay so if you've never seen it overfilled spilling out then damage has not been done to the evap system yet. is that correct? I've only done it a few times. I won't anymore.
