Over the last 30 years or so I have rebuilt or refreshed many automotive engines. I have noticed engines that have used Pennzoil exclusively have cleaner components without the sludge build up I've seen with other oil. These Pennzoil engines consistently showed less wear on bearings and piston skirts as compared with engines of equal mileage when compared with other brand oils.

[This review was collected as part of a promotion.] Ever since I started using it in my truck, the truck has performed better and it seems to last longer than other oils I've run in it. Used to just run around the Air Force Base, and now living in Florida, it still seems to out last others.

[This review was collected as part of a promotion.] I started using Pennzoil when I got my first car in 1980 my father used it and all my uncles so I did I glad my car when I got it had way over 100,000 miles but the guy that owned it before me took care of it also with Pennzoil oil I use 10/30 weight in most cars still unless I put the high mileage oil in now my 3 grow kids use Pennzoil also and my granddaughter is 9 but her father is a ASE Mechanic and uses Pennzoil also so she will too! so that is 4 generations using Pennzoil products and wouldn't use anything else.

[This review was collected as part of a promotion.] I've used Pennzoil Conventional Oil in most of my vehicles for years. No better conventional oil exists. The only vehicles that didn't use Pennzoil Conventional in my garage were the ones that I converted to full synthetic.

[This review was collected as part of a promotion.] I have always used Pennzoil in my Ford Mavericks, and still do! I trust Pennzoil to give my engine the protection it needs, I drive my Maverick hard, I need an oil that works hard to protect my engine.

[This review was collected as part of a promotion.] We've used this oil in the past in our older cars, we've also used the high mileage oil for our higher mileage vehicles. Usually for the price it's a good deal. I know a lot of delivery drivers use this oil because of the number of miles the put on and the age and mileage of their vehicles. Haven't heard any complaints.

[This review was collected as part of a promotion.] Ive used pennzoil in all my cars my dad a grandpa do as well always was told to use it because it was the best I've never had any problems with my cars as far as oil goes so I will continue to buy pennzoil as long as I drive

My husband does all our oil changes...only product he'll use. His work car is a Subaru with 368k miles on it...runs like a dream! When other brands are on sale and I want him to save a few $? Nope! Tried and true...not taking a chance with another brand. Thanks for a great product.

I've always used this brand it seems to last the longest I run it in my trucks and motorcycles, the outdoor 2 cycle oil seems to be the best also I've always run it in my bikes and wouldnt buy anything else. I'd run it in anything that's 2 stroke new or old.

Great oil for a great price. Keep up the great work!
