Reviews of PENNZOIL engine oil

I used to only use Mobil-1, now I use Penzzoil. I go with whoever has the best rebate at the time. they are all fine.

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.

I've been using Pennzoil Platinum in my 2010 for a few years. I saw how it was the best oil tested on Project Farm on YouTube. I get it for $27 for a 5-quart jug at Walmart.

For Pennzoil, I always use the Ultra platinum over the standard platinum. It has been tested to have lower friction and higher addictive content.

I have had a much better experience with Pennzoil in Japanese cars. Pennzoil is a bit better.

Don’t use royal purple heard so many bad things about how it’s not a good brand anymore, I swapped to penzoil oil plantinum 5/30 and honestly the car feels a lot smoother and sounds a lil less ticki but still I’d recommend anything other than royal purple

5w30 pennzoil, doesnt make the vtc rattle with that oil, mobil 1 sucks i would stay away from it it also burns much faster

One poster said it right; Amsoil is a Multi Level Marketing program and that's why it's so expensive. Yes it's great oil, however, the Penzoil ULTRA Platinum is high in detergents that keep your engine clean. It's made of natural gas, an industry first, and is so pure and clear you can hardly see it on your dipstick.

I always run 5w30 Pennzoil Platinum in mine. I have run other brands, but I have settled on this. Easy to get, often on sale, excellent oil.

Pennzoil Ultra Platinum in my 2016 Focus ST. It seems to love it. Quieter idle, great gas mileage, drives smoother after a cold start.
