[This review was collected as part of a promotion.] I use to use other brands of oil and when I became a Mechanic and started working on cars once I seen the different effects oils had on the inside of engines it made me a believer that depending on what brand oil you use has a lot to do with your engines life. I made the switch over 20 years ago and cant find one bad thing to say about Pennzoil. If you want to take care of your engine and extend your engines life span without spending a lot in repairs use Pennzoil I've seen inside of many engines and with Pennzoil it keeps the inside looking new.

[This review was collected as part of a promotion.] I have been used Pennzoil for years now. I have been over on milage on my oil changes both my vechicals I have not had a problem at all with my 4.2 vortech in my 02 trailblazer or my 2.2 chevy Cavalier 1996 great engine oil y'all

[This review was collected as part of a promotion.] I have always used Pennzoil in my cars. I have often seen other motor oils on sale for a cheaper price than what I pay for Pennzoil but I'll stick with Pennzoil because it may be cheaper but most likely the quality is cheaper too! Pennzoil is the best!

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.] I use Pennzoil active in just about all of my toys. Its hard to find a good convetinal motor oil anymore now that everything can run senthetic. I need the conventional oil to run in my 1972 Chevy c10. I also use it my 2 dirt bikes and all of our ATVs. Stuff is just perfect. You can't ask for better and the price is way less then it is worth. I really enjoy your product and so does the rest of my family!

[This review was collected as part of a promotion.] I have been using this in my F150 from the 1st time I had the oil changed. As of today I have 189563 miles on this truck, I have not had any oil related problems, and never have to add oil between changes. I may switch to high mileage pennzoil, when I reach 250000. Thanks for making a great product.

[This review was collected as part of a promotion.] I used this "plain" Pennzoil for years in a lot of mostly older cars, i.e., "beaters", and had really good results doing so. Everyone is so excited about synthetic oils these days, and while they are excellent, they tend to be quite costly. It's good to know that Pennzoil's "basic" product has been great for years, and has also been improved over the years. An excellent product at a reasonable price!

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.

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 !!!!

[This review was collected as part of a promotion.] Multiple cars and suvs over the years and I've always trusted Pennzoil. It's always kept them running smoothly until my next oil change. It's a tradition passed down from my father when changing the oil in all of his vehicles.
