Reviews of PENNZOIL engine oil

Pennzoil is fine, definitely not the best though (my 9th Gen si burned a lot using it) if you can get Mobil 1 or Castrol l I’d go for them instead and use an oem filter.

I use full synthetic all the time, either Pennzoil Platinum or Mobil 1.

I ran Pennzoil XLF in all my two strokes for years with no probs. Good price and readily available at Wal-Mart, Amazon, etc. Quality oil and lower smoke than many.

I use Pennzoil ultra platinum and my car runs great I change it every 5K. I use mazda oem oil filters since they don’t have the anti drain back valve.

Pennzoil high mileage synthetic. I've burnt/leaked far less fuel since I started using it.

I use Pennzoil Platinum after FordBossMe turned me onto it and did some (quite detailed) review videos covering it versus the other ones such as Mobil1 and Valvoline

Pretty much as soon as I switched to Pennzoil Platinum (the one made from natural gas) my engine ***suddenly*** got noticeably quieter. Previously with the Mobil1 it was making faint clicking/lifter noise during the first few minutes of driving

Starts are quieter too, with the Mobil1 it made some light clatter/metallic-y noises on those very first 1-3 seconds of startup, but now with the Pennzoil Platinum it purrs up smoothly from the moment I turn the key

I use Pennzoil Platinum Full Synthetic in my 21 Forester. $23 for 5qt from Walmart and $12 oil filter from dealership.

Project farm did a bunch of tests on all popular oil brands and amsoil won followed closely by pennzoil ultra platinum. The pennzoil is easier to get so that’s what I use on all my cars.

I like running pennzoil euro platinum 5w40.

I used Valvoline synthetic in my first SHO, and I am using Mobile 1 in my latest SHO. I tried Pennzoil in my 5.0 (Windsor) and all the lifters started clattering.
