What grade gas do you use. - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I have been using 87 grade for over 3+ years with no issues. 94k miles.

Anyone else use the low grade stuff? Figure I saved about $2500 in gas cost so far.

I use 93 octane, but I buy the $1 gas station coffee which saves me $3 over dunkin dounuts so it's kind of a wash.

93. Your car is probably pulling timing on 87, but it probably won't hurt anything. The engineers probably accounted for at least some amount of neglect.

91 because there's no 93 out here.

They did. That is why 93 is recommended but 91 is REQURED. False economy if it eventually screws up the engine. Think how much could be saved if you never changed your oil!
Next post will probably be "How can I get more power"?

premium. the manual says it will run on regular, but i noticed pinging occasionally while doing so, it's just not worth the potential hassle.

Fearing moving back to CA for a multitude of reasons, the worst (after state income tax of course) is the unavailability of 93 octane pump gas

eastendraceshop · 01-31-2019, 02:40 PM

91 here in CA

PetrolioBenzina · 01-31-2019, 02:41 PM

E95, listed as 105 octane, 3.10/gal. Good stuff.

Borchert97 · 01-31-2019, 02:42 PM

92 because that's what premium is local to the Seattle area. I haven't seen 93 around here although I am aware it's the recommended grade. When I did my road trip to Minnesota, I encountered a few scenarios where I was stuck with 87 or even fucking 85 because I was out in the middle of nowhere in Montana, on the fuel light, and had to stop at some local ma and pa gas station in a town with a population of like 200. Luckily I carried a gallon of 92 with me that I mixed with a few gallons of 85 to make ~87. Got back into civilization shortly after and found some 93.

I've never found any but I've been wanting to try 105, how does it run? You don't need a tune for that right?

No it doesn't it says 91 which is still premium.

I don't think the OP understands what the numbers mean and feels that it is just a quality thing. It is not.

Needs a tune for ethanol, using the OFT. Surprisingly strong running, and probably how it shoulda/coulda come from the factory.
