[This review was collected as part of a promotion.] I use Pennzoil in my 360 Sprint Car and it never lets me down. After switching to SAE 25W-50 GT Performance Racing Motor Oil my engine always looks new when apart for freshening. Thanks Pennzoil !

[This review was collected as part of a promotion.] This motor oil is the product that my husband and I both use in our personal automobiles. We find that it is a great and reliable product, which ensures the best quality at an affordable price.

[This review was collected as part of a promotion.] I always get a Pennzoil oil change and am so glad that I do because I know my car is protected with the best oil there is.

[This review was collected as part of a promotion.] My ol 2000 Ford truck has a whooping 311000 miles on it and still running strong on Pennzoil 5w-30 and I'll keep it that way till I wear it out.

I own serveral vehicles ranging from a 1965 mustang to a 1998 expedition. I have tried other products but nothing matches the performance of Pennzoil.
