2015 Tahoe LT
Didn't think I'd change my mine, for years I've used Mobil-1, but I had to revise my thinking when I was discussing motor oil with my friend next door. It's pretty clear that Mobil-1 isn't the do all oil I was lead to believe and used over the years. So I ordered 9 quarts of Pennzoil Ultra synthetic 0W/20 for my L83 and a few PH-63 filters in my 2015 Tahoe. Oil is a strange thing when you think about it, we all have a "favorite" and how that particular brand came to be a Favorite is a odd kind of thing. But sooner or later we decide to find something better. Amsoil is the best by a good lead, That said, it's expensive when buying 9 quarts. I change the oil every 4-5 months or 4.000 miles no matter how many often I used the truck.
