[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.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

[This review was collected as part of a promotion.] I usually take my F-150 in to have the oil changed but decided to do it myself. This is some quality motor oil. With the Pennzoil name you know it will be good. I have never tried full synthetic in my truck but with it's higher mileage I think this will work well. I have used Pennzoil products for years in my boats so I have no reason to believe this will be anything but excellent.

[This review was collected as part of a promotion.] This is a very good oil that produces a very good used oil analysis reports. It appears to do a very good job of keeping the internal clean, And although not designed as a long drain interval oil you can’t push the limit. For instance I’ve went 15,000 miles with a turbo.

[This review was collected as part of a promotion.] So I changed my oil at jiffy lube and always used the synthetic and I never knew how easy it was to change your own oil. This oil works great and I would recommend to use. My car has a 150k miles on it and it ran smooth

[This review was collected as part of a promotion.] I bought this to try the Pennzoil brand on the full Synthetic oil and seems to be good quality, used it on my 2015 jeep renegade, will see after 1000 miles how is the color and texture, the kit is convenient and had enough oil for the change

[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.] This Pennzoil Full Synthetic oil was super easy to use it made for great performance in my vehicle. It was easy to distribute with the shape of the bottle. I absolutely stand behind this brand. I would not turn to anything else.

[This review was collected as part of a promotion.] I have always used Pennzoil products in all of my engines. When I recently purchased a newer car, I had the chance to run the full synthetic. Now I have changed over to the full synthetic in every application possible. This stuff is the good stuff! Great bottles with easy to open/pour packaging.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.
