[This review was collected as part of a promotion.] I started off using Pennzoil because Dad did but as time went I became a loyal user as I used and abused my 1970 'Cuda and the motor held up. I have continually used Pennzoil products in all my cars because when I buy a car, I like to keep it around for a while.

I have used this oil for over 40 years my dad used the same oil. And I used it in my first new pick up truck and when we tore the oil pan off to check the mains and rods it looked like a brand new motor I had over 450,000 miles.The oil was changed every 2,500 miles the oil is great and I still use it in all 4 of mt trucks.

[This review was collected as part of a promotion.] Every month or sooner my father gets a bottle of Pennzoil from Family Dollar for his truck, even uses it as wax for his trunk to wipe it off after he washes his truck and shines the tires with it too!

We have been using this in my Great grandfathers 1968 Cub Cadet since he bought it new. Original engine no internal repairs have been done and it mows 3-5 acres weekly along with winter duty such as plowing and snowplowing. Thank You Pennsoil for making such a great motor oil !!!!

I usually have my oil change at stores that carry Penzoil....because I have owned a lot of different cars, makes and models and they all ran with out major engine problems...yes I keep 'em well past 100k....I can only attribute it to regular oil changes with Pennzoil..

[This review was collected as part of a promotion.] When I was a teenager my Dad always used Pennzoil. We would change oil in the car in our driveway. When I turned 16 and got my own car, a 1973 Monte Carlo. Loved that car and my Dad told me we needed to change the oil. When we went to get the oil he said it had to be Pennzoil. I ask why Pennzoil because all my friends used Valvoline motor oil. He said Pennzoil was the best and it would never fail me. That's been 31 years ago and I still use it and my Dad was right it has never failed me. Now I have three kids that all drive and I have taught them the same values my Dad taught me. We change oil in the driveway. Thanks Pennzoil for always being there for me and my family. Jimmy Oneal

[This review was collected as part of a promotion.] I have used Pennzoil since I started driving back in the late 60 . It's never let me down . I have 5 cars two with over 100k and one with 250k the other two have lower miles on them but I've never had one failure from this oil . I highly recommend it !

[This review was collected as part of a promotion.] When I used to change my own oil at home, I used this brand. With the car having free oil changes for life, I'm sure they use something else,Too bad really. I always liked watching their ads on tv back in the 70's and 80;s

There's something about going back to the classics. All these companies and bargain brands you try, you never know what's gonna happen to your engine. Penzoil is the brand everyone knows, trusts, and no matter where you are you know you can always ask for it and they'll have it.

[This review was collected as part of a promotion.] My father only uses pennzoil and it is all I have ever used. My truck Has 200,000 miles and the engine still runs like new. The truck maybe rusting and falling apart but my engine still has its power and punch.
