PLEASE READ: OCTANE question for '04 GTS

[darkayden]

Did you go to the same gas station each time you filled up with the different octane? Also which gas station did you use?

Good point! Extremly important

In my 2000 gts (2zz) owner's manual it says to use 95 octane. I can only find 93 at my local gas stations. Anyone else find this number in their owner's manual?

Yes, my 2000 GTS runs better on 95 octane. I mix 1/4 tank of 100 octane with 3/4 tank of 93 octane, and it is quicker.

Hmm intresting Ive notice putting 91 on my 1990 GT and it seems it gets less mpg . I usually pump 89 Oct from Mobil. I dont knoe if my gt needs to use 87 Oct. If so how high are the risk of getting engine knocks

Here in the NW we only have 91 octane... 93 is plenty. Anything above 93 and your getting into race gas which doesn't do anything for our engines without a properly tuned ECU.
