I guess yours has a different one listed because it's a 2019. My 2020 manual never mentions pf63e for v6 or any motor.The manual I downloaded from My Chevrolet says it should be an AC Delco PF63e (GM Part# 19330000). This is for the v6.
When I looked up UPF63r on Amazon, it said it does not fit my v6 Blazer. But the again it also said the PF63e didn’t fit ?
That sounds nice. I guess if they do a good job, and use high quality oil, and filter. You would just have to avoid all the up sell tactics.Got free oil changes for life at the dealer when purchased. They said to come in every 5000 miles, so that is what I will do.
