German Castrol Syntec 0/30.
My 02 z28 had a slight piston slap on cold starts with all other synthetics. I have never heard it since using this oil and for the $ it’s hard to beat. GM also recommends this in colder climates so they can’t try any BS if something goes wrong that requires warranty work.
