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.

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.

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.

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.
