Higher Octane on GTS = more timing?
My owner's manual says I need 91 Octane. I ran with Esso 91 octane since I bought the car, then the other day there was a gas sale at Chevron, so I put in Octane 92 ... & I noticed a difference, like more steady, smoother, harder pulls throughout the RPM band. Now I was wondering if going to Octane 94 is even better? Will the ECU advance timing based on what Octane Gas your using? Cause I know advance timing seems to give more jump to a car.

the car will run better the higher the octane but no real big jump in power. even if you go up to 100 octane. you may see 1-3 hp if you're lucky.


Best 60' 1.959 best 1/4 - 13.7 @ 101mph

yes, the higher the octane the better, but as far as the noticible differences, I'm sorry to say but most of the time its just in your head. You'll only notice a descent difference on a large octane jump.

^^^ It isn't always better to use higher octane. There was a post a while back about GT owners using premo gas and feeling less power, and quite a few people agreed that some of the gas might not have been burning off. I can see that as entirely possible if you're using something like 100 octane on a stock GTS.

Well here in OZ our celicas are made for 95 ron fuel, but if you put in 91, it will retard timing, so I guess you will notice a difference..

On a GT is a totally different story as its running lower compression. So 87 is good enough. But on a GTS with higher compression, the higher octane is necessary plus I really think it thrives on it, but only up to a certain point...like 94 tops, 100 is overkill.
