[This review was collected as part of a promotion.] I bought this for my 67 mustang that is my everyday driver and have not had one issue with pennzoil oil.

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

When i bought my first product from penzoil i wasnt sure about it. I noticed that the oil is cheaper than most and is the most reliable oil i have put it my car! I wont use anything else

I only used Pennzoil conventional in my Rx-8 - the mechanics that worked on it always commented how clean the components were. It's the only oil I know I can trust!

[This review was collected as part of a promotion.] Pens oil was the oil my father recommended I buy when I first started driving 31 years ago. I believe they are still the leaders in this industry,

[This review was collected as part of a promotion.] Been using Pennsville for 25 years on numerous vehicles and have never encountered any engine wear problems. EVER.

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!

[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.] my hubby swears by Pennzoil from his 1930 model A ratrod on down the line.. wonderful product equals beyond happy customer

[This review was collected as part of a promotion.] You know I've always used Penzoil in my vehicles simply because there's oil and then there's Penzoil. Nuff said.
