My father and I had a repair business for 30 years, and we used Pennzoil for all our engine work. It always held up well in a variety of engines, kept them running well for our customers. Today I still use Pennzoil in my own vehicles.

I love Pennzoil, and always use it! My father retired from there and has past away now and I have a big collection of Pennzoil stuff,so I would love to have one of these

[This review was collected as part of a promotion.] Penn oil has been a top notch product in every engine I have very owned. From my 1960 ford falcon to my 2013 chevy sonic to my husky lawnmower I will never use anything else.

[This review was collected as part of a promotion.] 112000 miles no problems. My whole family uses this product and no problem with any engines from cars to trucks.

A relative used this(not the racing version) is his Chev V8, straight 30w, when he set a drag racing class world record. He says it never let him down. That's good enough for me too!
