91 octane highest around?

[skitxoz]

I just moved to highlands ranch last week and have noticed that there is only a 91 octane at the gas stations.

In baltimore i used 93 and 94 with my turbo setup.

Anyone know if the 91 will hurt my cars performance. or does the altitude make up for the lack of octane?

thanks

Just curious, but what do you drive?

You should be fine with 91 as long as you don't turn up the boost. You might find a few with 93 around but most likely have to get some race gas...

Lots of choices. You are in Littleton, so you are close to Duggans.

As you go up in elevation the effective compression of an engine goes down and so does the octane leval available.
