Engine oil PENNZOIL or OEM BMW
have run penzz plat 5-30 for the entire life of the car almost, recently switched to the high mileage version as im pushing almost 150k miles on it.
i use pennzoil plat every 3k seems to be fine for the past 57k miles
I go every 5k using Pennzoil Platinum 5w-30, though it's just a stock engine/tune and more than half are highway miles
I do in my BMW. Oil is cheap compared to a re and re on a diesel no longer sold in country.
The engine itself runs great with the 48K I put on it in the past 2.5 years with biannual oil changes (Pennzoil Ultra Platinum). Averaging 27 MPGs on 91 Octane hwy miles, 24-25 mpg in the city.
I drive a 2021 RAM 1500 Classic and use only Pennzoil Ultra Platinum with the extended guard filter cartridges. I change my filter cartridge at 5,000 miles and reset my light then at around 10,000 miles, I change the oil and cartridge. There was one time I forgot to change my oil before winter and didn't feel like doing it in the cold so I ended up around 15,000 miles before changing it. The oil was still fairly clean.
Synthetic oil change is now $125 at the stealership so Ibu my own 0/50 Penzoil and a high quality filter every year, and vacuum out the Hybrid Traction battery filter myself
0-20 pennsoil synthetic with a wix or napa filter
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
