Default Re: High/medium/ low grade! What octane for your china girl!

Gotta run 93 octane premium here too... it's just a waste of money to run it in a stock setup with barely 85 to 90 psi compression pressure, but once you get past 120 psi or so the higher octane premium is needed. Mine reads 145 psi when tested.
