Engine oil PENNZOIL or Pentosin

I run penzoil ultra platinum. I’ll spend the extra money to know that I might get a few more hours out of my gen.

Luckily modern oils are developed with this in mind. Costco/walmart/amazon oil is made by the same company, Warren oil. I think most people consider penzoil ultra platinum as one of the best.

I use Pennzoil Ultra Platinum 5w-30. It’s hasn’t failed me yet and I’ve done multiple track days

Pennzoil ultra platinum 5w-30 in my 2016. Will use it in wife's 2025 when warranty is done.

Honestly, any brand should be okay as long as you change your oil every 5k miles. Personally I run Penz ultra plat. I never burn oil with it and my engine sounds quieter than it did w/ Mobil 1.

Put about 300K on two different M54's so far. Originally Mobil1/Castrol 0W30 (that was the original BMW recommendation in early 2000s), eventually switched to Pennzoil Euro 5W40 for oil leak reduction.

I switched to Pennzoil Ultra Platinum full synthetic made from natural gas. Oil consumption is 1/2qt in 5K.

I flip between Pennzoil Ultra Platinum and Motul depending on if I choose to order ahead of time or just do it when I feel like.

Pennzoil Platinum Ultra is also commonly used/recommended instead of the Motul and is cheaper.

I would run Castrol over Pennzoil. Coming from personal experience, Pennzoil is junk.
