Engine oil PENNZOIL or OEM BMW

Unless you are tracking the car you aren\u2019t going to see a difference. I use Pennzoil ultra platinum and a wix filter on my daily\u2019s.

Pennzoil Ultra Platinum, better than mobil 1, but also I am pretty sure all oil is within a few percentage points of performance anymore anyways, and it really doesn't matter as long as you change it when you should.

Great oil, I go with the Ultra Platinum. So far it's been the absolute quietest (based on subjective valvetrain sound) and smoothest driving oil I ever used. I tried OEM, Valvoline, Castrol. Nothing was as smooth as the Pennzoil even after a few thousand miles. I still change it every 5k for peace of mind.

I swear by penz ultra platinum/euro platinum in my cars. Really good anti wear additive package in that stuff.

I use Pennzoil Platinum. It's made from natural gas, a cleaner base than crude. My engine loves it. Minimal consumption between oil changes and no leaks.

I went with Pennzoil Ultra Platinum 5w-30. 20k on the clock of my 2023 and it doesn’t burn a drop of oil. I changed the oil at 1k and 3k after that and it always comes out looking beautifully.

Pennsoil 0w30 is a great oil

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.

Been using the recommended bmw 5w-30 up until recently. However been having to top up 5L every month so the shop switched over to 10w-40 and I haven't seen that I needed to top up yet, but it has only been one and half months so far since the service.

Pennzoil UP was on a sale and I bought 15 quarts, my Sierra dropped a lifter within 200 miles of the OC and switch, related, no way, will I ever use Pennzoil UP again, no way.
