Planning on doing my own services and not letting the dealership do them. I have always run Mobil 1 Full Synthetic in my LS Engine cars. I questioned it when i built my LS1 because the cam bearings didnt look that great for always staying on top of my oil changes but i found out that for the mileage i had it was about normal. My LS3 has 20,000 miles on it so should 5w-30 Mobil 1 Full Synthetic be just fine and at what mileage should i step it up to 10w30? Thank you for the help.
