i am thinking 89-91 octane---not sure on which brand you owners feel is best? suggestions?

 

Do a search. There have already been several threads on octane and brands of gas.

 

True. If your car is designed to run on 87, which it is, and if it's stock, you'll gain nothing by running a higher octane it it. It's just tossing away money.

 

Not true, i believe it was MM&FF that gained 2.7hp or something like that by switchin to 91 octane. If thats worth it to you, go for it, otherwise id just stick with chevron 87.

 

My 1st choice is Shell (according to a list I read, they don't import from the Persian Gulf - the place that hates Americans and the West in general and are killing our men and women. See this link: Oil Import Info


My 2nd choice is Chevron

See this link: Previous Tread

 

The only way that you will gain horse power when you change the octane of your gas is if your car's computer is tuned for the higher octane gas. Otherwise it is a waste to use a higher than recommended gas in your car.

 

All gas comes from the same place, its shipped in pipelines, everyones gas mixes with everyones else. Just watched a show on this 2 days ago. Say Shell buys X amount at the source, they can take that same amount out now at the end of the pipeline in the same day, even though it takes weeks for it to travel that far. The only things that makes one persons gas different from another, is the additives they put it in, pure and simple, cant argue facts. Shell only has their "good stuff" in the high octane, at least around here which i think is stupid. Chevron has it in all grades.

 

Sunoco 87 or Sunoco 101, depends on how fat your wallet is and if your car is designed to run on High Test. Stock stick with 87 unless you get a tune. And it is a good idea to pick a brand and stick with it so different additives or "sludge" from different refinerys wont mix together well.

 

Fazm,

Which show was that? I got my info directly off the government website for complilation of oil companies and where they get there oil from, as mentioned in the link by mlcrisis. Comanies without their own refineries will use another's but I believe Shell has their own. Just curious cause the data on the gov website was very thorough.

Thanks

 

If I have a choice I always go for Shell.

 

Interesting you mentioned sludge. I just saw a Castrol commercial touting it fights sludge. It seems we're going to see a lot of sludge fighting claims now that some modern engines have failed due to it. Saab, Toyota, VW, Audi, Chrysler.. SLUDGE LINK Manufacturers extending engine warranties due to sludge problems

top tier gas

 

i was at the race track and was going to put some 104 octane in but at 5.50 a gallon that was just crazy....

 

It works like this:

Let's say there are three refineries on the Texas Gulf Coast owned by Shell, BP, and Chevron. Let's say that Shell refines 500,000 barrels of gasoline, BP refines 300,000 and Chevron 400,000. All 1,200,000 barrels of gasoline goes into the same pipeline and is sent up north where it is then split up into the quantities that each company put into the pipeline. Here's the tricky part: all that gas gets mixed up in the pipe. Even though Shell buys it's oil from somewhere else than the Middle East, the gas you pump at the Shell station may have actually originated at a BP or Chevron refinery. The only thing that makes it "Shell gas" are the additives. The base gasoline could come from anywhere.

How do I know this you ask? I work in the petrochemical industry.

 

Great info Mark.

Gas is Gas in my opinion. They have to meet government regulations and if they didn't they wouldn't be in business. I have purchased cheap gas for all of my cars and I will not change until I see some substantial evidence that I should.

 

This I can believe is very true and it makes sense. And apparently the additives to make up "whichever brand" can change the final product.

My 1st choice will still be Shell, since at least my money to Shell won't filter over to benefit the SOB's killing my fellow Americans.

 

Thanks Mark. Yeah I guess each company doesn't have it's own proprietary pipeline. It'd get very crowded and expensive, wouldn't it

Very good info


So since my car is running stock on 87 octane just put the cheapest I can find? There's a non name brand station here that is 2.19 for regular.

EDIT: just read mlcrisis' comment above and it reminded me of this but forgot to write it when replying, supporting Shell though will keep my money from going into the hands of middle east oil. So even though I may be getting middle east oil in my car, they're not getting my money.

 

Actually, I think using 89 octane your engine computer could advance the timing a little. But anything further than that would be a waste of money. If you want more power out of higer octane get a tuner

 

Isn't Shell a Conglomerate Based in Holland and selling World wide?

It seems impossible that they are not buying Mid East Crude.

 

I think it is stupid try and descriminate between fuels... better to pay more attention to what YOUR car is doing... and get a tuner for godsake
