I searched the thread and havnt found any of them that are mainly Gas related.

I for one only use regular Chevron i think 87 octane rating. If i cant get to a chevron station then ill go to a 76 station. And if there is no 76 ill settle for anything else.

Does higher octane give any advantages in certain generations because i know that in my 2nd gen 95 4runner I get no milage increase but maybe a little more acceleration when i go with the best gas which is 92 octane.

I know many people will have their opinions on certain gas and this thread is not here for people to argue whats the best gas ever made but to determine whats a better gas in terms of milage, reliability, and long term use.

Id like to hear eveyones expierences with different gases.

Whate me do:

Lowest octane (87-88) from only good stations (Shell, Chevron, Texaco, settle for Exxon if nothing else).

Slowrunner

Chevron 92 octane only because it pings. 91 octane from others work but not as good.

personally i'm of the belief that it doesn't matter where you buy your fuel from. it all comes from the same storage tanks in your local area. as far as octane goes, you're best bet is to go with the lowest that doesn't knock in your engine. when your engine knocks, the knock sensor retards the timing which cuts power. running high octante will never give you more power, but running low octane will take away power (if it knocks). octane is just a measure of knock resistance compared to a standard test solution. i.e. 87 octane fuel is resistant to knock just like a mixture of 87% octane and 13% heptane. there is no correlation of energy content and octane. for more info see this:

however, there's one guy who says he's a chemist (i'm a chemist too, but not a combustion chemist, so i don't know the all the details about combustion) who has different opinions than i do. i'm including this link for completeness, but if you go by base rates of articles, there are more (credible) articles that agree with me than disagree.

We had a 93 22re pickup and run 87 fine with it. We had an ignition on it so it may helped or may not. It was ok with 87.

I run 89 in my 4Runner so it doesn't knock, 87 in my Taco.

Anyone seen that show on gasoline on the science channel? What it shows is that the gasoline distribution system in the entire nation is a fungible system. That is that all companies put the same stuff in and get the same stuff out, just not likely that it will be the same stuff you put in. Lets say that you put one barrel of oil in the plant down in Texas, then you can get the equivalent value out in gasoline the same day say up in New York, even though it is really a 7 day transfer time, almost like a bank. All the gasoline brands use the same distribution pipes and storage tanks too. Even more amazing is that they ship different products, ie diesel and unleaded right in the same pipe seperated by nothing at all. Yes they do intermix somewhat and this is filtered out at the destination tanks. The only difference between brands is the chemicals they put in at the very end in the truck just before it drives to your local station. They say on the TV show that the only difference between brands is who can market it better to convince you to pay more at the pump! Primarliy because back in the day there was a big difference, now it is negligible. Just sharing the info on the show, don't kill the messenger if you swear by Shell gasoline or whatever!

Here is a link to a map of the us distribution system

I'll go look at the TIVO right now and see it it is on again soon. Blew me away how much infastructure is in place that you never see.

Around here we have 95 and 98 octane gas only.

viperdan

87 here, usually shell, only because its right across the street from where I live

Up here the regular is 85 octane, but I have to run 87 so it won't knock. Plus owner's manual says to run minimum of 87. For some reason my truck runs better on Shell gas than conoco or exxon. Strange. Back home in GA I normally buy from QT.

i put 85 because it is the cheapest and becuse the gas price went up and that is bull˟˟˟˟˟
