[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

I'm very happy with the way this does in my car compared to others.

Have used this every time I have my oil changed and have never been disappointed.

This is an awesome product and we only use Pennzoil! Will never switch!
