Living in CO, we get mostly crappy gas with all sorts of additives especially during winter. I know there have to be some stations here with 93, how can I find them?

 

Do you really need it? At 6000 or whatever feet in Boulder, your engine has a lot lower cylinder pressures, therefore requiring lower octane gas. I would think that the 90 or 91 you can get easily there should suffice.

If you want higher octane for the track for whatever reason, just buy a bottle of 104+ or whatever octane booster.

Really, you don't need the high octane at the higher elevations. That's why the gas stations carry lower octane gas. Them Fed boys that control da gas iz smart wit stuff like dat.

 

yeah, you don't really need high octane at those altitiudes. 89 would probably be more than enough and you might even be able to get away with 87.

 

just use the highest octane found in ur area, no need to get high octane since u r in a high elevation state. i would also recommend not to use octane boost or race fuel for track...not necessary for our engines and will not help(if u have any forced induction on the other hand, it's different).

 

Ya man your car will run fine on 91 and the only place you will find higher than that is probably at bandimere or some performance shops.
