[This review was collected as part of a promotion.] Great motor oil! I switched to synthetic on a few of my high mileage vehicles and I’m convinced that Pennzoil has increased the life of them! I know they say you can run longer between oil changes with synthetic but I still change it at 3k. 180k on one of my trucks and still runs like new!!

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic is my oil of choice when it comes to all my lawn and garden equipment. I truly trust this oil and know that it will perform at its best and keep my equipment running at peek performance. The full synthetic is what I prefer to use and I know the Pennzoil brand is a name I can trust for ongoing performance. Highly recommend

[This review was collected as part of a promotion.] Excellent performance and protection. One of the best in the market, have observed that slight increase in mileage and the car runs smoother. Also last quite longer before oil changes that the other brands. Can't go wrong with this one

[This review was collected as part of a promotion.] Pennzoil Full Synthetic 5w30 case of 6 is very convenient and a bit cheaper to buy than buying 6 individual. We have several vehicles so need to buy a lot of oil. Best oil we've bought in a while its quality is superb

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. It is the only oil that goes into them. The full synthetic is absolutely the best, I will continue to use this going forward. If you're looking for a full synthetic oil, this is it.

[This review was collected as part of a promotion.] I just received this motor oil a couple days ago and I really like the way it makes my car preforms. I know when I am using this product my car is going to work the way it is supposed to do. I highly recommend this product for everyone.

[This review was collected as part of a promotion.] I got the Pennzoil Full Synthetic 5w-20. If you change your own oil this is the oil for you. Pennzoil Full Synthetic motor oil is made from natural gas which makes it much more pure than oil made from crude. It is proven to provide better protection and lasts longer than oil made from crude. Compared to other oil Pennzoil works great on my 2008 Dodge Ram pickup with high mileage .I would definitely recommend.

[This review was collected as part of a promotion.] I bought this oil for my 2016 civic after learning how to cahnge my car oil myself. We have been using this brand since my cars first oil change at 5k. Never had a problem, never burns or low after 5k hard city driving.

[This review was collected as part of a promotion.] I started using pennzoils full synthetic oil on both my trucks about a year ago. Long lasting...I typically go about 7,500 miles between oil changes and the oil still looks good when I drain it. Could probably go another 7,500. Not all oils are of the highest quality as pennzoil
