Does the FRS need 87, 89, 91, or 93 gas? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I put 93 in mine since my choices are 87, 89 or 93. The book says 91 minimum. There is a loooong thread in this if you search.

91 or 93. 93 is best but 91 is ok. Anything below is bad or may lead to future issues. I put in 89 once (3/4 tank of it) because nothing over that was around for 40miles and car ran sluggish. Seemed like it really needed to try in order to maintain hwy speed. I quickly burnt that off and once I got to Chevron, put in 91. It ran sluggish(ly) up until the second time I pumped in 91.

Manual states premium only as so does the sticker on the cap or near it. Will help prevent knocking (and sometimes crickets).

IIRC in gas door have a label wich oct rate need to be fill

When in doubt: purchase the gas with the highest octane (aka the most expensive one).

PS (useless info) if you make the mistake of trying to fill up with diesel the nozzle won't fit.

Okay looks like this subject has been beat to death. Thanks guys for responding anyways. Mods can shut this down if they want to.

I dunno about everyone else but I use race gas.

Is that why I am hearing crickets from my engine bay?

Half 89 and half 93 to make it 91

Sarcasm does not translate well over the web. Especially for someone as blunt as me LOL

Well we have a lot of it here so you will learn fast or get into a pile of unwarranted arguments.

100LL Avgas should work well as Subaru engines are used for airplanes and there's no crappy ethanol blended into aviation gas. Try it and let us know how it goes. Just a little more lead than auto fuel though...but that 108 AKI equivalent octane man...should be making boat loads of power with a tune!
