Is 93 Octane available?
Is 93 octane available in your area? I'm having hard time finding 93. 91 is readily available at almost every station, but not 93. I wonder how this affects performance? The manual says to use 93 or 91 if 93 not available. If the car is tuned to 93, should it be adjusted to 91 to get better performance?

I have a mix of 93 and 91 around me.... depends on the stations brand. I consistantly use one gas station. Their quality of gas stays high and always makes my Grand National happy, which is happiest with a true 93 octane with the tune it has. They happen to be a Sunoco station.

Virtually every pump in TX. Same with E85 if I'm not mistaken. I've never inspected it but often see a yellow pump.

93 is available all over Long Island NY. I have to use it in my GT350 and Denali. And I will be using it in my ZL1 whenever it gets here. I haven't checked into it,can we use E85 in the ZL1?

Just make sure the 104 doesn't have lead in. I still have older cans of it with lead added.

No 93 at a standard station here in SoCal (I believe it is all of California, but I am not an expert about up north, so I won't say for sure),...at the racetrack you can get some good gas lol...we probably have some of the worst gas in the country here. Even some stations that say they are 91 octane...are not...pretty bad.

Every pump here in my area of NC has 93, haven't seen 91 in a long time.
