Re: for '14 does eother engine require Premium fuel?
Yep, dealer put 87 in mine when they delivered it. I just filled up with 89 and don't really notice any power or performance difference. I'm sure there is, but like others mentioned, they computer will handle the difference and make it almost completely blind to the driver.
