What fuel do you put on your FRS/BRZ?

[N1rve]

91 from Costco only.

87 on a leased car regardless the manual says

So you want less horsepower and more potential problems since it's a lease? Makes sense.

[FRS Johnny]

anyone have any input on 91 gas from costco or sams club? How is it?

I too, have used Shell 91 from day one and have rather loud crickets... could be localized.

I have been switching back and forth on shell 91 or husky 94 depending if I want MOARPOWER or goos milage

Esso/Exxonmobil 98. The fuel in HK is great and super-expensive anyway, so why not?

Due to low fuel, I once had to put in a 1/3 tank of Sinopec/Petrochina, which slightly gutted me, but to be fair I didn't really notice any change.

i used 91 mobile. Seems to be the only thing that removes the chirps here in so cal in the 626. Tried cheveron and shell but had chirps. If there was 93 here i wouldnt mind paying the extra to using it.

So maybe what needs to happen is we all get together and do some kind of spec analysis of each gas locally. I'm not a gas scientist or anything but if gas companies have different ratios of mixtures in different states, it might be something strange like Shell 91 in AZ is closer to Chevron 91 in CA than Shell 91 in CA, or something.

91 ARCO. I get a ARCO gas card from my work.

How is the different? Got the car on dyno? Found 1 sunoco close to mu place and wanna try your formula ^^

Most of the time Shell 91, and sometimes Chevron. Still have crickets but I don't hear it with music and my exhaust :P

[MstrSHAKE]

Shell 93. Crickets louder than ever

Had to look at a blending chart to see what octane you were shooting for. I tried the mixing every once in a while, when I was somewhat close to a 76 station that had 100 octane, but it eventually became too much effort to get to the station. Props to you for continually doing it!

I use 76 or Chevron 91. Funny enough my first car (1990 Ford Escort) towards the end of it's life would only really run smoothly with Chevron. Supposedly the Techron helped, although I have no hard evidence other than my car dying most of the time I didn't use Chevron.
