I have a 6.2 GDI motor in my new 2018 Silverado which is basically the same motor with different cam , intake and other things. I would think a truck motor would be subject to harsher environment and running conditions just from the weight difference between the two vehicles let alone if any towing is done with the truck. I drained the factory fill 0 20 after the first 800 miles and have been running 5 30 Mobil EP. Seeing the new spec 0 40 for the Corvette has me wanting to use that during next oil change. Thoughts?
0W-40 for the Corvette is in case for track use. Do you track your truck? 6000 RPM? They allow dexos1 Gen 2 5W-30 otherwise. Also, 0W-40 FS is calcium-based full-SAPS ("FS") and definitely quite off-the-spec for your truck.
If 0W-20 is the factory spec, go with the PAO-based M1 EP 0W-20 SN PLUS. You won't get a better off-the-shelf oil in US. With the PAO/POE base oil and Infineum organic friction modifier (OFM), your engine will run and sound as smooth as it can.
