Toyota Gasoline?, Preference Options

[JoKeRkId613]

I'm about to supercharge my car and know that I will be using premium grade fuel. Is there any Toyota-preferred gasoline company? I did a search and it seems Ferrari recommends Shell. I'm no Ferrari, but I usually fill up at BP (Amoco). I remember seeing a list a while back with a few gas companies that are better for Toyota engines because of something in the gas. Does anyone have that? or does anyone if there is a recommended company by Toyota?

I know this won't make a noticeable difference, but figured since gas prices are pretty mcuh the same around town I might as well fill up at the best place.

Thanks.

Shell is the best quality gasoline there is period.
The detergent and addative aspects are better than others

shell > all

its no longer shell, they got bought out by americagas

i use shell and sunoco all the time. I seriously wont fill up at any where but. Even if Im gonna run out of gas, i will push my car to find a station. Ive only filled up at 1 other type of station once in 2 years because i was in the midel of no where and ran out of gas.

gas is gas. brand names are just clever marketing to get you to think there is something magical in that tank of gas you just overpaid for.

[LewFX]

i use chevron, its on toyotas recommended list

[playr158]

gas isn't gas....I'm accquantences with a very experienced, rider, racer and employee of BG. Very Very knowledgable man, they are different...

but AMEN for overpriced....wtf $3.19 a gallon....thank god for 3.5 gallon tank!

the top three companies with the best addatives are:
SHELL/CHEVRON

so shell it is.

edit: anyone know if shell is on the list?

its like motor oil and oil filters. youll always see people swear by one or another based on brand name and marketing, not really based on what they are really buying.

i was just watching a commercial on tv about how shell gas would reduce gunk built up. they showed the top of a valve covered in oil sludge. anyone who knows a thing or two about cars would be able to tell you that something like that has more to do with oil then it does with gas. or there is a commercial for quaker state motor oil that will help you unlock all 300 "horses" from your sti. its all bull**** marketing.

My imput shouldnt count though, cuz gas here is different than gas in the states. We have different additives, and also we are only legaly allowed to have a certain octane rating to be sold as daily fuel. If you wanna get any thing over 100 octane you have to buy special race fuel from a race fuel supplier. Like just regular 100 octane gas, or C12 has to be bought some a liscence dealer. Theres apparently some subtil differences between our gas and the US gas.

That sludge build up is because of oil and gas mixing and the oil breaking down. So it does have something to do with gas, if you have crappy internals. Also oil can free up HP if you use the right formula for the weather and operating conditions. Also some oils like royal purple have been tested and show HP improvments..not majour..like 5 or 6HP on a Z06, but nothing majour.

top tier fuel isnt all bull. some fuels really do have manufacturer recommended amounts of additives while others really do not!

i'll tell you one thing tho, you can tell alot about fuels and oils by running them in a 2 stroke. penzoil 2 stroke oil and some random brand 93 octane made some HARD deposits which built up FAST. mobil1 2T and shell 93 left almost no deposits and what was left is very soft and easy to clean.

go put your car on a dyno. youll see + or - 6hp just between runs without changing anything.

the engine would have to have very bad compression for gas to ever mix with the oil. and if thats the case, engine oil sludge would be the least of someones problems.

a little gas always mixes with your oil, but most of it vaporizes again and is burnt (what the PCV does).

I try to only use Shell.
Gas is not gas when places like Arco add water to it.

Hehehe... you guys sure buy into "gimmicks" pretty easily. Granted the fuels are slightly different due to processing differences and additives, but it's not gonna matter to the engine unless it has something to do with octane. Even still, higher octane only makes the fuel more resistant to pre detonation. It has nothing to do with power really... and the ONLY cars that REQUIRE high octane fuel are those with higher compression... say 10:5 or higher... or if they're heavily boosted and generate a LOT more heat...

I use Arco, subsidiary of BP... It's cheap and it's got AM/PM.

Cheap fuel ftw!

Do you really believe what you are saying? Octane has a lot to do with power even if it's just to keep the ECU from pulling back timing. Also diff gas manufacturers use diff additives which does have an effect on deposits and such. Are you actually saying you can't feel a difference between Stop And Go or Grocery store gas and say Chevron or Exxon? There isn't that much difference between the major comanies though.
Just because you haven't paid that much attention doesn't mean there isn't a difference or it's a "gimmick". And isn't your car turbo?
We could go back and forth about this all day but I swear by Chevron and Exxon and I've actually had a mechanic years ago ask me if I ran Chevron gas all the time and he was right. He said I had some of the cleanest used valves he had ever seen. Plus I can feel a difference on the butt dyno and I'm pretty sure I've seen studies on it before using a real dyno. may not be huge differences but they are differences you can feel and that's enough for me.
BTW - I work in the gas refining industry also. Not that that makes me an expert or anything.

Did you READ what I wrote? Additives and such are just gimmicks... All of that crap they feed you about "reducing deposits" and such are all just gimmicks. Why? ALL fuels do the same thing. There is no "cleaning" element to fuel because it's already mixed with air and in a split second, already vaporized and burned. The reason for deposits and such form is almost always because of dirty PCV systems. As for octane... learn what octane does to an engine before you claim it can affect power. LOL. Octane just makes fuel more resistant to pre detonation. That has NOTHING to do with how an engine makes power. It however... alleviates a negative side-effect of tuning. In other words... octane itself doesn't "improve" performance... but because it makes fuel more resistant, the engine can in turn be tuned more agressively. Higher compression, more agressive fuel maps, more agressive ignition curves... things that typically generate more heat.

FYI 6gc GT's are 9:5 compression. A FAR cry from 10:5. If you wanna discuss this... know your facts. You can swear by whatever you want... but seriously... fuel is fuel. Like I said previously, additives are just gimmicks. They do not adversely affect the way an engine works etc. Octane can potentially affect an engine's performance based on the tune... BUT... will do NOTHING for a stock motor that isn't designed to run on higher octane fuel.
