Would using this oil cause a problem in my 2013 4.8 V8? I'm just curious if it will quiet down its occasionally noisy lifters that I hear with 5w30 Mobil 1. The 100 viscosity is 12.9, which is barely more than the upper tolerance for 5w30. Can anyone thing of a reason why this would be harmful to the engine? The only thing I worry about are the cam phasers for VVT. You think I'd be okay?
Is not having that ILSAC GF-5 designation a go home foul?
