We have bought this brand many many years. My dad was a mechanic and he passed at age of 92 and taught me in his garage that this is the oil to use!

[This review was collected as part of a promotion.] Been driving for 25 years.....nothing but Pennzoil touches my car....

Run this oil in my 1969 Camaro and in my dad's 1984 El Camino. Keeps them running strong and on the road!

I buy this for my cars it helps it keep runing no matter what I've tried other oils but it never comperes to the quality of Pennzoil conventionol

Have been using this on all my cars. Thumbs up best darn oil I have ever used and the only oil I use and recommend period.
