90q What grade of Fuel?

[David]

The 90q would have a 2.3ltr NG engine like the one in my CGT with a CR of ~10.1:1...should be using Premium to avoid knock. The NG has pretty weak pistons that can't take much pinging before melting. But it does have a knokc sensor, so it SHOULD be ok even on 87, but you will hurt performance...
