[This review was collected as part of a promotion.] Only type of oil I will use since we rebuilt engine

This is the oil my Dad used in everything he owned. Including our Ford farm tractor. I grew up with it. My Mustang gets it too!

I've been a Pennzoil user and fan all my life and for all of my vehicle's lives. Excellent product, I wouldn't trust anything else.

[This review was collected as part of a promotion.] nice and slick. nice oil smell. Made my bearings slippery!

[This review was collected as part of a promotion.] Been using it a long time in all of my rides Thanks

[This review was collected as part of a promotion.] I have been using it for years 40+ years with great performance

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

[This review was collected as part of a promotion.] Make engines run longer and keeps everything lubed well and clean.

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