cam.in.head Posted September 11, 2023 Share Posted September 11, 2023 according to the haynes info that engine was manufactured after march 1985 so it should have a cylinder head marked P2E meaning it is suitable for unleaded fuel. these engines (and obviously the cars too) wernt designed for ethanol fuel so if i were you i would just run it on the super high octane stuff which is low or zero ethanol. other than that ,what do you need to know. ? 1 Quote Link to comment Share on other sites More sharing options...
