Chevron 94 Octane or Esso 91

Chevron has worked the best for me. Shell has been the worst for me. Depending on actual location, your mileage may vary.

Strangely enough when we live in Hawaii and driving a BMW it was the other way around.

It does not matter as long as it is top tier.

I can only get 91, which sucks. I sure wish I could get 93 or 94 whatever you guys get.

I would always go to Chevron, but it's much more expensive for me (about 20 cents per gallon).

I use Shell 91 most of time. Sometimes I use 76's 91. Both are on the top tier gasoline lists alongside Chevron that was assembled by auto makers including BMW.

I use anything from Arco, shell, mobil, 76 all premium of course. Honestly all I feel is in my wallet. I avoid no name brand gasoline though

I prefer Mobil over the rest. more common and worked with my previous cars.
plus its the most common in NYC

Exxon 91 and Chevron 91, depending on whether I fill up near work, or near home.

Here's a link for those of you in Cali for 100 octane

Oh, and do a blend if you ever go to one of those spots.

1/3 of your tank in 100-octane (4-5 gallons), and top off with 91. Should give you about a 94-95 octane rating.

Shell and Chevron are both top tier.

why, is 100 octane straight up too hard on the engine or something?

PhaseNine

As long as it is 93 and above I dont care where it comes from, but I wont use Valero, The Racetrac stations around here have 110 at the pump $6.99 a gallon

Dema

Valero, good milleage, low price.

norcal5

Have been using Costco 91 octane gas with no problems

RLE

Aviation gasoline contains lead and will kill the 02 sensors and the cats and your warranty.

Go Ahead.

I usually use these brands. A couple of tanks ago I put in a lesser brand, same 92 octane, and immediately felt less power and experienced worse mpg. I'm now on the 2nd fillup post that and the mpg is coming back; maybe another tank?

Might be there was more water in that off-brand gas? I've used it in other cars without problem, but then I've never had the running mpg computer before ;-)
