Works good, second time I've used Pennzoil and probably far from my last. I know they have good engineering built into their product

[This review was collected as part of a promotion.] Been running it in my truck for years. Haven't had any problems.

[This review was collected as part of a promotion.] Penzoil is the best oil, we've been using it for many years

Jeep doesn't run rough, & there are no metal shavings in the oil when I change it. No problems with it whether I'm trail riding or on the highway!

[This review was collected as part of a promotion.] I only run Pennzoil motor oil in all of my vehicles... it never fails to exceed expectations...a beautiful golden, clear, hard-working oil.

[This review was collected as part of a promotion.] I never see a difference except in the price. What can I say I'm not the guy that takes his motor apart after trying oil.

[This review was collected as part of a promotion.] I mean it's ok, I run royal purple in my rig but used pennzoil for my grandparents car for their last oil change and it seems ok

This is what we use for all of our vehicles... Reliable, affordable, and out performs all others!

i use this on every oil change on any of my cars!!

i always used pennzoil in all my cars never had a problem great oil
