Yea I have a stock plane as can be 2013 GT mustang. And I was wondering if I should use premium. Or stick with the regular fuel?
while I know it is for the 2011, the engine is the same for the 2011-2013 years in everyway.OK cool I think I'm gonna stick with premium.
Stick with regular, the new 5.0s are able to electronically adjust to a higher octane of fuel. But you still won't see anywhere near as much gain as you would with a tune.
What? You just contradicted yourself.That's what i would do also lol
Not quite, there has been a big debate as to when the piston oil squirrels were deleted, also the pistons are slightly different where they use more ring skirts I believe. Different timing tables and tuning also.while I know it is for the 2011, the engine is the same for the 2011-2013 years in everyway.
