I was running Royal Purple 5w-20 til making the switch to the Castrol Syntec 0w-30.
My car seems to run smoother all around, but it's only been a day at this point. We'll see how it does for the next 4k-5k
Ive been using Amsoil 5w-20 since Ive had the car. Even when I drain the old oil it still looks good.
