I posted on a Facebook group for Silverados and Sierras that I went with a 5W-30 over the 0W-20. Basically to let people know that it’s quieter and bumped my hot oil pressure up from 18psi to 22psi. There are a lot of people asking on there about what oil to run, and I just wanted to give some actual experience. Boy oh boy, I wasn’t expecting the oil experts to show up
One guy, who claims to be an ASE Master Certified and a GM Master Tech basically told me that my engine was going to sludge up because of the 30 weight. He said my decision, and others like me, keep him in business? It’s one OCI LOL. He also claims that there are “tons” of TSBs from GM about having to use a 0W-20 in these EcoTec3 engines. That’s when I knew he wasn’t telling the truth…
I’m by far no oil expert, but I’ve been around here long enough, and read enough to know better. I tried to educate this “expert” and his friends, but that went no where fast. Now, for the last 3 days it’s become a nightly activity to troll this guy and his buddies on my post. It’s an honest living, and someone’s got to do it.
