Engine oil Shell or PENNZOIL

Tried other brands pero Shell pa rin talaga

I only run 5-40 Full Synthetic on my Armada and all my vehicles in the past. I've never had an issue and only changed the oil once a year or whenever 7500 miles hit. As for what brand, Shell Rotella T6 5-40.

Penzoil is the only "clean" oil. It's made from natural gas rather than crude oil. So that in itself is beneficial when talking about deposits left in your engine vs other oil brands.

For experience using pennzoil. Really good stuff

I run pennzoil 5w30 ultra platinum. ... PUP is great for direct injected turbo. Anthony (Dmann) told me that PUP 5w30 is the way to go in western PA

I've been using Pennzoil Ultra Platinum since the first change in my 2016. Prior to that, I used it exclusively in my RX-8 that made it to 154k on the original engine.

Rotella T6 5w-40 is what I’ve ran in the car ever since it was tuned and I get great feedback from blackstone labs when sending in my oil for analysis.

Original owner ran Pennzoil ultra platinum and that I got 289,000 miles on that engine and turbo before I had a shop rebuilt it.

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

I tried pennzoil and didn't like it. The engine developed a soft tick after about 3k miles. Went back to Castrol and the tick hasn't returned.
