I have a 2018 Chevy Tahoe with a 5.3 V8, which I'm currently running Pennzoil Platinum 0W-20 and also a 2018 GMC Acadia with a 3.6 V6 running Mobil 1 5W-30.
I'm thinking of switching to Shell Rotella For Gas Truck 0W-20 for the Tahoe and the same in 5W-30 for the Acadia for my next oil changes.
I'm more anxious to switching the Acadia than I am the Tahoe, because of the Acadia's past history with timing chain issues. My grandfather used to be an over the road trucker, back in the 1950's and a diesel mechanic for years after that, so I grew up on Shell Rotella oil, because of the high detergents, and how clean it kept an engine. I know the synthetic isn't the same formulation as the Dino was, however, I, am assuming that the synthetic version is very high detergent also.
I only put about six thousand miles on the Acadia in the first year, and am on track to put on the same for the Tahoe, so I'm going for 5k OCI. Most of my driving is trips shorter than ten miles at a time, and rarely do I drive twenty miles or more anymore, I do, but, not more than once every couple weeks.
I figure if I start with a higher detergent oil early on in the life of the engine, and stick with it, it will give me a happy motor for a long, long, time. I've used Mobil 1 since I got away from my grandpa changing my oil in the late seventies, but, I'm switching back to all Shell products. No fault of Mobil 1, I have been plenty happy with it over the years. We are using Pennzoil Platinum and Quaker State Ultimate Durability in our eight work vehicles. We have noticed in the Nissan Frontiers, and Toyota Tacoma's, is that those oils, seem to be quiet oils, at least more so than the Dino we were running before.
