proper fuel for my engine ?
Evening everyone
My engine setup is a stock 5.3 with 862 heads = 9:5:1 compression ratio
But my intake is an LS1 with 27 lb/hr injectors
I should be using 87 - 89 octane correct?
- it won't affect the injectors correct?

At higher elevation, 85 octane is common and fine to use.
