Curiosity got the best of me today.
I got 8 qts of Mobil Delvac 1300 15W40 and did an oil change on my 2015 silverado 5.3L
I was curious what differences in oil pressure there would be since it seems it has always stayed about the same for the last 120k miles. Weather its 20* F starts or Summer time.
Since the new vettes are using 0W40 i figured it would do no harm to try in the truck.
Oil pressure is only 5psi higher than it was before (M1 0W20). I was supprised it wasnt higher. Driving 70 hwy its about 45 psi now whereas before it was about ~38. Hot idle before was ~30-32 now its probly ~35
Still silent running. Feel like i lost A tiny bit of response from a stop with light throttle( like in a parking lot ).
Just gonna run it for a short oci and go back to my stash of 20wt M1.
