    Gas and Oil Gurus needed

    I drive a car with a 5.7 Hemi engine - The recommended fuel is midgrade 89 octane. I have noticed the car runs better if I use premium 91 octane fuel. My question - Is there a greater risk of fuel dillution to my 5w-20 oil running 91 vs 89 octane gas. I usually use Castrol Syntec 5w-20.
