Re: How well does the GTP run on 10% ethanol
I run 87 octane in all of my other vehicles with no problems at all. Now my question is specifically for the GTP's supercharged 3.8. GM's reccomendation as well as other GTP owners is to use premium fuel. Will 89 or 90 octane 10% ethanol blend work or is necessary to use high octane non-ethanol gas?
