Engine oil PENNZOIL or AMSOIL

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.

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.

Been running PU since with no problems.

I used Amsoil Signature when I was driving 1300 miles a week just so I could go two months between oil changes.

I change oil once per year, using a high-quality synthetic that meets specification 504. I generally drive 8 to 9 thousand miles per year. The maker of the oil I use (Amsoil) says to follow the car maker's change interval.

Penzoil the best!

For me at least, I use a 5w-30 Amsoil on my TLX Type S.

I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.

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.
