- Testing two different fuels to see if there is any power difference between the two in my 2014 Dodge Charger R/T!
The results are pretty surprising to me, is this what you expected?
Help a brother out and please like and share this video as it took me forever to do!

I've been driving the same truck for the last 14 years and I always use 87 Oct . yesterday I used 93 octain. And yes there is a difference I can tell a huge. Increase in power I know this truck like the back of my hand.
Yesssir
Same I used to use 87 in my car but now I use 91 and it's way better
Yeah and you can cause your car to knock
Reset your ltkr and stkr and get some timing back.
Bruh quit lying, I believe they call that the placebo effect 😂 btw that’s not how you spell octane 🤦♂️
Appreciate that experiment man. Getting one tommorow and this saved me from going to has up and run all the variables in my head. Appreciate you wasting money, time, and gas for other charger lovers!
That in my humble opinion was a very well done test, especially for not being in a controlled environment etc etc. And thank you for not throwing a whole lot of personal bias into the mix, that was refreshing as well. I for one would really like to see a test with the 5.7 between 87 octane, and the 93 octane. Overall gas mileage for a tank, and your tests from 40 to 80 and maybe a few more 0 to 60 and I would love to see the 40 to 80 in third gear, I think it would put the engine more in it's comfort zone, where it's designed to operate with a little performance. I mean let's face it Mopar turned a truck hemi into a really nice small block with a lot of horses for its size in 2011. Not to mention how much performance you can actually get out of one of these if you want. Anyway thank you, great video and now a subscriber.
Love your vids man. You're very knowledgeable. Huge fan here!
Just bought my '14 HEMI yesterday man! Helpful vid. Thanks dude!
+iDj Swift Welcome to the Hemi fam! Enjoy it!!
Hey! I really enjoy your videos and am considering getting an R/T myself real soon. I do think you should mention(in the description) what mods you have done to the vehicle though, because the mods could affect whether or not your motor will enjoy the higher octane.
This has been a great video since I go back and forth between 89 and 93. Now the factory tune requires 89, so I'm sure they have some sort of rhyme /reason for that.
Anyways - For what it's worth, it's a breath of fresh air to finally read comments without interjections from Internet trolls. That in itself was worth reading all the responses. Nice!
+Frank Burrell Thanks Frank! Glad I was able to help you out!
+Frank & Stephanie Burrell Octane tunes are directly proportional to engine compression ratio. Octane is literally a measure of how much compression a fuel can take before self-combusting (i.e., before top dead center and spark).
Thank you so much for this !!!! It was very helpful.
Good video and thanks for taking the time out to do this research without using a dyno....kudos...👍🏾
I will just stick with 89 the recommended fuel. The 5.7 engine factory tuning does not have much flexibility for other grades of fuel. The knock sensors are heavily used running 87 when the engine is under load, with less power being the result, but most drivers will not notice that. For 93 octane with an aftermarket tune you can make more power, but with a factory tune the difference is not noticeable.
Great video, great car! I have been driving around the 2015 charger v6 since last May and I absolutely love it. I can't wait until I graduate university and et the 2015 R/T. I have couple comments on the video regarding the testing, some stuff that you could have done in a better way. For instance when you filled it with 93, you filled it all the way to the max you mentioned, but you only put 16 gallons the first run. That could account for some extra weight. Second, I think it would be a better test if you were on a straight way rather going up or downhill. These are not major stuff, but these could make a small difference when testing! Overall great video, can't say I'm surprised with the results though! Keep em comin (Y)
+Wael Salem Both sets of test were done with full tanks of their appropriate gas. 89 octane filled up with 16.92 gallons while the 93 octane filled up with 16.67 gallons. The test locations aren't perfectly flat but I did 4 runs in the same spots for each fuel to keep it consistent. Thanks for the comment though and enjoy your charger!
That was a good video. The high octane rating used to be mandatory for a high compression engine to keep from detonating. It is no longer the case. The Ford 5.0 has an engine management system that is off the charts. It has an 11 to 1 compression ratio, but can still run on 87 octane. It does drop in HP, but the .60 cents a gallon you save is worth it.
Octane # is not about power or energy in fuel, its more about when it will detonate. Thats why engines with higher compression ratio need higher octane fuel. afair - alcohol based fuels have octane numbers more than 100, lol, but you will get worse mpg ( less energy per gallon, basically ) with it.
Dmitry Alekhin thank you
Thank you for writing all of this so i dont have too lol. I hate when people think octane is associated with power.
Octane is associated with power, when you consider that the ecu will pull timing (take power away) if it detects any knock. It's been noted before, and even insinuated by Chrysler/Dodge, that you will lose performance using 87 vs 89. Octane, in and of itself will not make power. But, when the ecm can add timing due to the higher octanes knock resistance, THAT will result in more power (however slight or significant that circumstantially may be)
Joe R power doesnt have everything to do with it. It is timing and compression. Hellcats are running 87 while the 6.4 is running 93. The 6.4 has a much higher compression because it is n/a. Now yes at one point the compression will be so high that you need an even higher octane. And power will follow but octane is not directly connected to power.
Sak 20012019 but it is associated with horsepower. In fact horsepower is dependent on octane. On an older car without a knock sensor, higher octane will not give you more power right off the bat and with no other changes. But with modern spark control, higher octane will net you more power if the car was designed for it. So in essence, higher octave doesn’t give horsepower, it allows it.
I've always been big on using 93 Octane even though it hurts the pocket book, but watching this I will definitely look into 89 octane. Thanks, good job on getting those numbers!
Heh.. the comment aged horribly 😂
Wish you compared 87 to 89 to see why they recommend 89.
Because. Let's say your favorite soda is Cola, and you refuse to drink anything else. You can have off brand Cola, or you can have Coca Cola. Both Cola, but one is better.
Its all about compression and timing. 94 is a waist of money unless it calls for it.
Joseph Kreifels II Right On!
Its a 7% change in horsepower when using 89 vs 87. I would just use 87 unless I'm racing because 7% is not enough to justify using 89
kcotte59 ...Evolution (which was just a “theory “ from Darwin) has never been proven to be true. It’s just a theory . There is no new fossil evidence (which even Darwin said was necessary) to support it. A religious person who doesn’t buy that crap shouldn’t be called an idiot. Btw, I especially hope that you don’t buy that “men evolved from ape” crap. Biggest joke of all. Also, I sure would have liked to see the 87 compared to the 89 !!!!!
Great job testing!
I had a mazda before my challenger, noticed even though mazda claimed 87 was best that 89 gave me 10mpg better gas mileage, and that's not even a joke. It shocked even the mazda dealership.
I tested the same thing in my v6 challenger, and get at least 5mpg better on 89 plus my engine sounds like its running smoother, i was getting a lot of what sounded like knocking on 87 like the owners manual said so again they should change it to ask for 89 due to just offering better gas mileage and a smoother running car.
I would also like to add that in the future i do hope to add a RIPP Supercharger to my challenger before it gets too high in miles. Should make it a lot more fun to drive.
Damn I wish gas was that cheap now. 2.11 for 93. 😂😂😂 it's like over $3 where I'm at now. Lol
LiL-A-407 it’s like $4 a gallon where I am! And I’m not sure why cause 87 is only $2.29 lol
FLA HEMI its 3.50s here
Well thank god i live in Saudi Arabia were 95 octane is $2.05 per gallon lmao 😂
And here in Canada for 91 its 1.40 per liter....
2018 - $1.47 / L in Toronto = $5.55 / Gallon
yes it does. on my focus ive tested 87-91-e85
the higher the octane, the higher the power increase beacause it allows the engine to make more power. the higher the octane rating the less preignition
Willy Q the burn changes and the power will usually decrease when not on proper tune. The engine will run on knock sensors.
did you still have fuel in the fuel line when did the test? Or did you drive a few miles to make sure you were completely running the new fuel?
hey man, really liked the review, seemed pretty well thought out. 2 things though....was your tire pressure in all tires the same on both days? idk if you know this or not but they say that a higher octane won't make a difference until you've put at least 3 or 4 tanks of it through your engine over time. thoughts/replies? thanks man!
You need a dyno to really test the difference
agree
agree, one test could have had a headwind, and the other could have been up or down a slight grade, and if you put it on a dyno you will see that there is no difference at all, like all the car reviews and marketplace reviews that have done the same testing, but with better control over the variables
denmalski there is a diference.
i know right, this test is outright insanity
You're right about the dyno test but you have to admit, these field tests are great for RUclips and for consumers trying to decide what vehicle to buy. If he's taking the time, effort AND money to do this, you have to appreciate it. As a Dodge muscle car owner, it's very cool to watch these
Good data, love seeing someone in CStat
Great test bro.
Well, I like the video. like someone else stated it would be nice to know the difference between 87, 89, and 93. Like the video though. Keep up the videos. :)
He looks like a young Abe Lincoln😂
Lmao
Dude i love your vids, they're very informative for aspiring Charger owners like me. I'm going to be so sad when you sell it :(
+Zelly Shaw Haha no worries there will still be many more with it and the content from the next car will be even better!
Dude your Murdered R/T looks pretty brilliant. What exhaust have you got?
The higher octane is definitely a more completely burning cleaner fuel. Which is good for your valves, pistons and the environment .
Now if he got a 93 octane tune he would be blown away ! Can highly recommend hemi fever 👍
Only works if you go 88 mph!
Hahahaha!
great video bro ! just what I was looking for, I use only 89 cause the 5.7 is not a high compression engine , 10.5:1 I think, but I was curious to see the difference between 89 and 93, thanks and keep it up man with the charger videos,, some good videos can be a camaro vs the charger or a 392 or a 5.0,
+elvicdesonora Thanks man glad I was able to help you out! Yeah I plan to do more of those soon when I'm able to make trips down to Mexico! :)
I run 89 in my 5.7 nice video thanks for posting
When I first bought my charger I was using 89 and I was getting 14-15 mpg in the city. then I heard that 93 octane was better for a V8 engine. So I been using 93 for a few months now and I'm getting 16-17 mpg so it does make a lil difference performance wise too it helps the car accelerate faster.
Yanil Valdez so I have a 2015 RT and I must say the car does pick up quicker on 93 vs 89 but I'm just wondering would using 93 harm anything in the long run being that it's recommended 89?
"...I heard that 93 octane was better for a V8 engine."
Be careful what you hear.
CAMARO SS305 the thing is if it recommend 89 and if we put 93 in won’t that fuck up ur engine up because that not what the car is used for
I have been using She'll 93 octane for over a year, it's advertised as a high detergent fuel, engine has gobs of power, 2009 challenger rt 5.7L.
So should I not bother putting 91 + an octane booster for my trip down to Phoenix AZ? I was only considering it because my 1993 Geo Prizm LSi 1.6L might need come help coming back up that hill lol.
riley I have a question. have you ever put E-85 in your charger?? are there any things that you have to change to run the E-85?? I have a 2016 dodge charger show car. I have put E3 diamond fire spark plugs in as well as a cold air intercooler. Dude you talk about an increase in HP. Man I am telling you it does make a difference. My gas mileage went up and so did the HP.
i ordered some headers and a mid pipe with mpt tune. Do i have to put the 93 octane first and then load up the tune? i usually put 89 on my car but since im getting a 93 tune do i have to empty out the 89, put the 93 in,and then load up the 93 tune? this is going to be my first time ever dealing with a tune i just want to make sure.
I've seen many tests with different cars between different fuels and everything comes out the same. I was told the difference is, the higher the Octane, the less likely it is to burn outside of the tank, in case of a fire. But I have no idea.
Do the same test with the 93 octane and add a bottle of the octane booster and see how that compares. Good job wit the vid
what state do you live in considering it was like 2.11 for a gallon of 93.
(SUV) Chevy Trailblazer 2002 LTZ 4WD: When I go on road trips i use plus(89) when i do city i use premium(93) I notice no difference HWY with plus or premium i do notice it with regular burns faster has terrible smell from muffler. Believe it or not... 20" rims GoodYear Tires All Terrain, Airaid Air cool Filter, Throttle Body Spray cleaning and Marvel Mystery OIL Spiked My performance and gas mileage by... 35% So get to it.
This is great, thanks! I have the same vehicle, wondered the same thing. My car is in for a partial rebuild under warranty, all he said was something about the cam, I thought the cylinder head was being rebuilt, either way it started to misfire on the second cylinder and when they went in, it's an $1800 job but it is covered under the powertrain warranty. I never get gas from anywhere but Chevron, Costco or Tom Thumb, interestingly, I started having problems with my old Charger after I moved here and started using Tom Thumb gas. The Costco gas 87 is OK, but I wish they had 91, my car never runs that great after a Costco fill up. My sensitive flower of a Hemi is happiest with Shell, even 87. Oh, I'm in Dallas and I was told to fill up at the station near the Winstar casino in OK, everyone goes on empty so they can fill up there something about the gas not having additives. It's expensive but wow does my car love this gas! Great mileage, smooth as silk, lots of power. Weird, huh! Thoughts?
+Reason Very strange! I've never heard of a gas station providing better gas! I always thought they were all about the same since the industry is so highly regulated!
thanks for the video. I have a 2015 ram 1500 5.7 hemi. I wonder if the octane effects the gas mileage
I use premium and I like to think it's healthier for that car rather than seeing a gain. I also realize this is an old vid, love the camaro btw
What were the engine temps and wind speed???? Did you eat breakfast that morning???
To any dodge charger owners..I have a 2012 rt... when I bought it guy was like regular is fine.. used reg, felt like it should be quicker but it was new to me so I didn't think anything of it..
then I read the manual after seeing this video and they recommend 91+ so I went to Chevron and shell and 76 did some testing.. 93 I feel makes it run too rich and fuel economy wasn't that great, so the happy medium after replacing all spark plugs and wires has been 91 Chevron! quick, and averaging 17 mpg!!! used to be in the low 13's with the same driving.. but after testing the high end gas stations my car likes Chevron 91...
never put Arco or any low gas.
I am always amazed that people switch octane and expect better or worse results. what you have to do whenever you switch fuel is wait till your almost empty fuel up with the new fuel then take your battery cables off for 20 minutes to kill all power in your system once hooked back up your on board computer will re-set to the new fuel.
It might not be good for racing, but it’s definitely good to clean your engine. High octane does clean your engine and that’s a fact. Higher octane has more detergents.
You should have tried shell v power nitro + is 93 and it there is difference between brands because of the quantity of detergent over the long run usage too. But really good video.
As of now I run 89 on my 5.7L Charger, my MPG is at 15.5. However I do have a Costco card but they don't sell 89 octane, I am considering running 91 octane for the better prices at Costco. Should I use 91?
How about the same test with a K&N Intake and performance computer tune, maybe even headers and then test the difference between 89 & 93 octane gas????
For me going to 91/93 made no difference on the seat dyno, what I liked was the fuel economy increase and how much smoother it ran. The plugs are cleaner and the MDS is much smoother.
Octane doesn't make you go faster. Octane, or AKI rating, is a measure of how much compression fuel can withstand before it combusts from pressure alone. Premature compression causes knock, which is extremely bad for engines. AKI = anti-knock index. The only power increase you'll see is if your car adjusts its compression & ignition in response to higher octane fuel. This would be a high-end, complex feature and gains would be minimal and perhaps even not measurable outside of a margin of error. It will also not increase fuel economy as higher octane does not increase the energy density of gasoline, so the same amount of high octane fuel is needed to produce the same energy as a lower octane fuel.
The reason higher-performance vehicles require higher octane fuel is, typically, the engines are tuned for maximum power and run as high a compression ratio as deemed safe for components by the manufacturer. The fuel itself is actually the bottleneck here in most cases.
When you are changing the pump gas for the one with higher octane rating you also need to adjust ignition timing accordingly and this us where you would gain extra power. On 5.7 L engine it would be about 30-40 flywheel HP all else being equal except ignition timing. Just changing the type of fuel ain't gonna make much difference...
Ive also been pumping 93 since I bought it in 2012. Idk if it helps or not, but I feel like it would make a big difference after 100k miles whether you've been filling up with discount gas or Shell V power, Ive been sticking with Shell btw
Chevron 94 😎
good video.. but does anyone have any input on a turbocharged engine. I have a 2.0 ecoboost ford fusion and read somewhere that I believe ford said I Gain 10hp from using premium fuel....??? I'm clueless on this if it works or not. and what does ford consider "premium"
I was always told to just go with whatever the factory recommends. Now I know why.
You should try racing fuel. I put it in my head 2010 just to see what it would do, and only did it one time. The car definitely ran different with 100 octane fuel. Just suggestion on my part. Btw at $8.50 a gallon it should run better.
I have a 5.7 Hemi and I have a predator tune which is set for 91 octane, but I put 93 octane in and it actually runs better on the 93 octane instead of 91
Love the "test facility" you used
Me too, there seems to be a lot of these around everywhere
The shifting is definitely a lot smoother, try 93 you will see the difference on the pedal
Very clear presentation. The video and sound were very good. Keep up the good work. Your 40 - 80 test in a tall gear did not make any sense. Is that the way you normally drive? Your engine would take advantage of the 93 octane if you let it wind up in in the optimal power range. If you were afraid of damaging your vehicle with some full throttle, high rpm accelerations, sell that dodge and get a Ford Mustang like the one you referenced in the beginning of your video. That Mustang owner was not afraid to wind up his ecoboost a few times. Good luck and hope to see you again.
The difference between 87/93 is very minimal on a factory tune. The knock sensors are calibrated in such a way from OEM that it's almost not worth it:depending on the type of car, of course. I am on my 2nd Charger (1st was an 08 Daytona, 2nd is '13 Daytona) and I have run both. The 93 is necessary after a tune. Does it run just fine without a tune? Of course. But as the numbers show, not always worth that extra few bucks per fill.
I have noticed a bigger difference on where I get my gas. If I am in a pinch and I go to a mom & pop corner store, my mileage suffers. If I run Shell, the car just seems to run a lot better. I know it does in my wife's EcoBoost Flex.
True I always use shell gasoline
If you have a custom tune, the octane does make a difference. On my 2004 Mustang GT, with 89 octane & tune, I produce 305 wheel horsepower. If I run the 93 octane & tune, I produce 315 wheel horsepower. So a tune can make all the difference
I don't know a ton about tuning these modern engines, but requir it in order for it to recognize the higher octane and would need to get into the computer to do that. Does anyone know if that is correct, or not ?
Its not a high-performance mill and only requires 89, so it wouldn't do anyting to begin with and should just save your money for mods that will do it some good
I personally don't get why you started in 4th gear, you aren't going to notice anything like that. You were better off letting the car stay in drive and auto select the gear it needed when you floored it. I've tried C12 in the tank and only noticed it was a bit more responsive and pulled a little harder but as for feeling a horsepower difference a dyno is the only way to see. Plus for the money, that's not even worth the test.
My 15 R/T has a mean 40 kick , I run mostly 93 , have seen the difference it makes at the track and on the street . Even higher will help too .. try sum octane boost ( a good kind ) ...
I'm not gunna lie bro this would be a good race between my v6 camaro and your charger I've beaten the 5.7 challenger with the Maro but mine has a lot of mods so I wouldn't go boasting about how I beat v8 but even if you did win you still have a v8 and I'm stuck with a v6 until I hit 20! Nice car btw way bro
Most newer cars with any amount of decent performance have the ability to ADVANCE TIMING what does this mean? The ECU will advance timing until it reaches the limit usually 93 octane on a stock tune... therefore the car will make maximum power that is can on that stock tune using 93 octane... if you ran 87 octane the ECU would have to pull timing thus resulting in a slower 0-60mph time , 1/4 mile time etc hope that helps... on fords twin turbo v6 motors they say that their torque/hp ratings are done with 93 octane.... using 87 octane is fine but the ECU will pull timing resulting in a slower acceleration best to use 93 if u care about max performance
hey bud, you should run a full tank of the 93 first then do the testing on the 2nd tank of 93. it takes a little bit for the computer to change all of the fuel trims that were stored from adaptive learning with the 87 or 89 you were previously running.
Have you made a video about the UConnect features and settings? I'm having trouble setting up the equalizer for the radio. But I also wanted to see if there was any other Things the UConnect does that maybe the car manual doesn't mention. I also own a 2014 Dodge R/T Blacktop, but mine is white with black leather. Great videos, keep it up!
+texasdc83 I don't have any specific videos on the UConnect system but I'm pretty familiar with it! What problem are you having with setting up the equalizer?
+RP Productions seems like the mids and bass can't go past half way without sounding like crap... I have the beats audio in it also
Hmmm I usually keep my bass and treble around 6 and the mid at +1. If it sounds bad I'd take it to the dealership and see what's up.
Shoulda get set up with a dyno and data logged the ecu to see what was going on in the engine. More knock?
Realize that going from 87 to 91 or 93 is considered a modification. Whenever you modify the ecu(cars computer) will change it's parameters to keep driving normal. The actual horsepower comes from tunning the ecu to actually increase horsepower for the modification, in this case the 93 octane. There really is a difference in power for different octane. But you will only see or feel them with a tune. Same with exhaust, intakes, or anything.
Can anybody tell me what type of gas the Ford Fusion SE 2017 2.5L take?
I think honestly it depends on your mods (if any) and how/where you drive. If I'm driving somewhere over 200 miles I'm putting 87 in my 2016 Charger R/T. even if gas mileage is better with 89/93 I'm paying way less per mile using 87 so I still win. Then again dodge recommends 89, 89 being best for performance and gas mileage as well as making the 5.7 last longer while giving out the best for longer. If I'm cruising around where I live just doing what I do I keep 89 in it, maybe if I was going to the track I'd put in 93 (I'm bone stock) but I still don't see it being much of a difference. My biggest concern overall engine life and dodge says 89 is the best.
A for effort my friend! but in no way accurate...too many variables to consider...but I enjoyed your enthusiasm..keep up the good work..great video
So. On a dyno, measuring max power, it’s legit 10hp difference between 87 and 89. The real difference comes into play on the highway, when your in eco. In 4cyl mode the computer advances timing, a lot. This why greater combustion is needed. Not for performance, but for economy. Now, if you get the vehicle tuned, 89 or 93 octane could greatly impact power. However, the factory ecm isn’t tuned for that
So I ran 93 in mine, got 25-26 mpg on the highway. 87 gave me about the same. 89, not even joking, I got about 29-30 mpg. Same route that I always take to Oklahoma. 89 just seems to give better performance/economy all around.
It does not sound like your transmission is down shifting far enough going 40-80. Mine seems to shift down lower. My 5.7 only has the K&N cold air intake added.
What mods do you have I get 6 second flat with my charger 07 5.7 hemi rt
I feel like with in time after constant use of 93, you would get better gas mileage, better spark and a bit quicker, same as synthetic oil use, healthier for the car, longer lasting, overall better quality.
these cars will pull timing with the 87 but 89 vs 93 is less of an issue as long as you use good fuel. the computer is programmed to use 89 stock. I use 91(no 93 in CA/NV) more because I get my fuel at Costco, they don't have 89. but when I get gas on the road I get 89. my car has the stock tune still. programmers can give you a 93/91 tune that would make a bigger difference.
Probably been said a lot of times but I am not going to read all 223 comments. Octane does not give you more power, just higher octane on higher compression engines resists knock(pre detonation) more. Knock is the cylinder combusting slightly before the piston hits TDC (top dead center) and this is not optimal. Modern engines, with all their computer components can adjust for knock (by varying valve timing, etc), but only so much. Higher octane is the true fix. This is why muscle cars (high compression) use fuels like turbo blue with 110+ octane. They want their cylinders to BANG right when it is supposed to. So other than some slightly better gas mileage, you wouldn't notice much else. HP doesn't really increase. You may notice the engine running a little better, but it's not like adding an aftermarket bolt on that increases HP. Good video though. Very thorough.
Is this with or without any mods to your car?
You started out with 89 so the pcm has learned the fuel trims for that octane. When you put 93 in it, you won't see any performance difference unless you reset the pcm fuel trims. This will also reset the changes made to the base timing due to the 89 octane. Basically the test in the video was a show of his 89 octane tune learned in the pcm.
Unless it completed a drive cycle between the time he put 93 in the car and the test.
If you have a car with higher compression and you run a lower octane gas you either have to pull timing or you will have detonation and spark knock. By running a higher octane you can run more timing and therefore make more horsepower. This is why drag cars run race fuel or alcohol.
KICK IT DOWN LETS HEAR THAT HEMI
just curious you are uaing the same road but the difference seems to bo in incline and decline in the road as well. Why not try 3rd gear.
Good video man. I think 89 will net you the best results just due to owners manual per say. But of course if you got a tune for the 93 it will net more power (added timing and blah blah). A good test too, i know you said you did the on off thing, but taking the battery off and reconnecting it might do a more of a reset. But I don't know much about chargers so can't say. Also one crazy thing is my friend as a 2008 police charger (r/t) and he happened to race a tundra the other night and lost. It was crazy. The truck looked completely stock. Don't know if this guy 4x4 launch it or what but he was about 3 car lengths in front of him.
rocklow243
Your friend might want to get his 08 pursuit model checked, there's no way that Tundra should have bested him. I operate a 2013 r/t, caught myself in race with a Porsche Cayenne the other day. I normally run 89 octane, Porsche could barely keep up. I hit 120 when he bailed out.
I use both 89 and 93 in my ram hemi and I do feel like there is more power using 93. It could be all in my head tho. I have used 87 and truck honestly felt sluggish and check engine light came on lol. So recommend not using 87 in your hemi.
Octane depends on your compression ratio, higher octane is for larger compression like 10 to 1
i put regular all the time and my car which is a 08 hemi charger sound like shit should i put a premium?
A professor at a local college where i live told my friend there is no difference between 87 and 93...not sure if i believe him but he has taught that to all his students
what about srt8 chraysler 2005/2010 octane 91 or 95 better ?
Your findings are hard to validate because there is so much more to how the engine will perform, with the outside temperatures and humidity being a big one. Seeings how the results were so close my take away is there is no difference.
I use ARAL (BP) Ultimate 102 Octane in Germany for my Mustang GT
how much mpg for each tank 89 vs 93 and also throw some 87 in there
its so anticlimatic when he steps on it lol
Its cause he had it in a higher gear n let it slowly climb.
He doesn’t know what he’s doing. He should’ve downshifted.
I have a Honda Civic Ex it states 87 or higher in the car Manuel.. So I am stuck with 89. I don’t want to go higher. The reason is not to go faster it’s a 1.8 engine, it’s because I have always heard from mechanics and high octane users that it helps clean your fuel system when you use a higher octane. I love my car. Is a 2007 by the way.It works great. I wouldn’t change nothing. I have been driving it for one and a half year and have been using 89 ever since I bought it.
