[This review was collected as part of a promotion.] I have been using Pennzoil products for 40+ years without an oil related engine failure. Pennzoil Full Synthetic Oil has kept my vehicles running smooth. This is a good quality oil at a good price. Highly recommend

[This review was collected as part of a promotion.] This oil is a good quality oil. I would say my engine has been running a bit smoother since I put this in my car. My car has always been a bit touchy, but since using this I notice it has been a bit more smooth. I won’t go back to my other oil.

[This review was collected as part of a promotion.] My car uses full synthetic or semi synthetic 5w20. I have never tried pennzoil before. Generally whatever the dealership puts in my car. But so far so good with pennzoil. I have used them in the past with conventional oil but not synthetic until now. So far I am very pleased with the product and their price point.

[This review was collected as part of a promotion.] Lasted 5k miles without burning just as it should. I put in about 3k miles a month, and it lasted me the whole months and a half before i got the time to do the next oil change. Definitely gets the job done

good oil to use in newer cars up to date tech.full synthetic is the way to go keep all parts clean and working grate. I use it in my2017 jeep wrangler with 85000 miles hard miles still runs like new.

20 below zero F in the Rockies or 115 in Palm Springs in July, synthetic provides great protection and smooth quiet engine performance. 0W-20 in 2015 jeep Renegade with 2.4 L 4 cyl engine.

I just brought this product today and changed the oil in my 2018 Mazda CX-5 sport. It’s my first time using pennzoil especially full synthetic. Let’s see how it ride and how fast the gas burns

Pennzoil and Quaker State only products now I use.
