[This review was collected as part of a promotion.] Pennzoil has always been a brand that I trust. I would never buy anything else! It's always worked for me, it's affordable, and does the job. I will most definitely be buying again.

[This review was collected as part of a promotion.] Have used Pennziol most of my adult life.... a great product and a name you can trust...... and when I service my car it comes out almost as clean as when it was put into the engine.

I drove a 1998 Ford Expedition until I sold it in 2015. Always used pennzoil and never had any major engine issues. Sold it with 150000 miles and it still ran great.
