Engine oil PENNZOIL or OEM Subaru

Pennzoil Euro Platinum 5w40. This oil is slept on but out performs most other expensive oils outside of Amsoil.

Nice work. My 2012 camryil4 se gets new oil every 3k 0-20 pennzoil ultra syn. 112,000 mi.

I had a 2017 Forester with 175k miles on it and only used factor oil and never had any issues. I did not do any off road stuff and it was only a premium model, not a wilderness model. I don’t think it matters as long as you change it regularly.

Penzoil Ultra Platinum 0-W20 @3-4K and Mobile 1 Extended Performance Oil Filter. I like that Penzoil derives their oil from natural gas.

Pennzoil Ultra Platinum has some of the best cold flow characteristics so I'm not in a hurry to change it even though it's 5W-30.

From what I've learned the best oil for the Turbo of any model with direct injection which Mazda uses is Pennzoil Ultra Platinum.

Use Penzoil Ultra Plat. Can probably stretch it to 5k miles with no issues.

I switched to 5w30 Pennzoil Ultra Platinum a long time ago on my 2.0T. 140k miles and running strong. FK8 CTR Turbo added around 133k, too. FBO PRL mods!

My 2024 Toyota Rav4 Prime XSE has had 2 used oil analysis tests done at 4k and 8k miles on Pennzoil Platinum 0w-16 and Eneos 0w-16. Both results showed both oils shearing lower and out of grade to a 0w-8 viscosity at 100C in 4k miles.

I know I was using penzoil back when I had a 90 325i, locked my engine up solid, mechanic said it had too much paraffin so yeah it matters personally I only use Mobil 1 synthetics
