Reviews of PENNZOIL engine oil

BMW switched from Castrol to Penzoil years ago...but both cause oil starvation in The S65 motor

I use Pennzoil platinum euro because its dirt cheap from walmart and meets all specs. 135,xxx kms so far on the same oil.

Best bang for your buck is the ultra premium penzoil 0w 20. Meets the api certification and in terms of performance it essentially provides the same level of performance as the amsoil.

I run Pennzoil Ultra Platinum 5w-30. My FK8 is making over 500hp no issues

For the money, Pennzoil can't be beat, and I say that considering you can usually get it from Napa or Amazon around $7/qt. Idemitsu is also great, but hovers around $8 or $9/qt on Amazon or Napa.

Pennzoil Ultra Platinum 5W 30 gas to liquid base oil construct $26 for 5 quarts at Walmart or Amazon and is perfect for EJFA engines. People running 0w20 in these fbs and fas and ejs are just destroying their engine. I run the 5W30 pencil Ultra Platinum. I would get the mow tool but it's just really not worth it. I changed my oil every 2,000 mi and the gas to liquid technology. Making your base stock backwards from natural gas gives perfect polymeric structure and their additive package. It's just smoking!  I can get three 5 quart bottles for for $75 on subscribe and save from Amazon delivered plus tax. I think the 5W30s The Sweet spot. Unless you're tracking it then I'd go up to the 0w 40 in the Pennzoil Ultra Platinum. But you have to realize that the same company that makes the base stock oil out of natural gas also owns the additive package company and they run a a 48 Esther ad pack in this and it's just tremendous oil. If I had higher mileage I'd be running. Probably Valvoline 5W30 restore and protect it. Cleans the ringlands, wrist pins, valve train etc. But since I changed my oil so frequently, I always stay with the pennsville Ultra Platinum. I don't think you can be eat it at $0.16 per ounce it's just bulletproof to thermal oxidation.

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

2013 Volvo XC 90. Owned since new, only used Penzoil Euro L formulation, all synthetic, 10W-30 and 143K miles later I had to get rid of her because I left the country. No engine issues at all.

Switched to Pennzoil Platinum for my current car and the engine is noticeably quieter (doesn't have the same mild clattery-ness from the valvetrain like with Mobil 1), and it doesn't burn either

I run Pennzoil almost exclusively. Especially, in my Dodge/Jeep because it meets the OE specifications.
