[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is the only motor oil I use in my cars simply because the brand’s oil provides superior protection for your engine and enhances its performance. What’s more, the oil removes all impurities in your engine by loosening the dirt and grime stuck between the moving parts of your engine. This allows for a smoother drive and cleaner engine that performs optimally for longer. We especially love the price because synthetic oil can be pricey. Pennzoil synthetic oil is affordable and more accessible and budget-friendly to consumers.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is their top of the line oil. I have used it for years and it keeps the engine clean and running great. Meets Chrysler and Ford specs along with many others. 5000 miles between oil changes is no issue!

[This review was collected as part of a promotion.] I love Pennzoil. I like the fact that it is made well without contaminants in the oil like regular base stock mineral oil. Works great and all the applications that I used it in for my jeep wrangler and suabru. I've found that cars I've used other oil on have had engine troubles, while I can prove a correlation I do believe this to be related.

[This review was collected as part of a promotion.] I am a huge supporter of the fully synthetic oil. Runs great in my jeep and I have never had an issue with it. I do all my oil changes myself and have been a pennzoil man through and through. Superior product at a superior price!!

It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles.

[This review was collected as part of a promotion.] Awesome oil as always and seems to work great in the car. I highly recommend this oil as it is all I have ever used in my vehicle. It is well worth it and seems to help the motor last a lot longer for some reason

[This review was collected as part of a promotion.] After some work to get my 2010 Mini Cooper running well again, the mechanic recommended this synthetic. So far, so good. The engine performance has been maintained, running nice and quietly, and I am not losing oil anymore. I have also been able to go to 6 month oil changes instead of 3 month oil changes, which easily offsets the slightly higher price.
