[This review was collected as part of a promotion.] This Pennzoil Synthetic oil keeps my baby running good and she's happy so I'm happy. I got a couple 1 quart bottle's and i poured them all in perfectly as i always do. I check ever quart by smelling it and i also give it a little taste and Pennzoil has a great taste so that's how i know it's good. lol

[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.] I used the Pennzoil Full Synthetic 5W-30 in my Chevrolet 6.0 after verifying it is Dexos approved. My mechanic commented that it is excellent oil. It functions well, holds good oil pressure and the engine ran cool and quiet.

[This review was collected as part of a promotion.] I have been using Pennzoil motor for as long as I can remember. It has always done me good and never had issues with my motors in any of the cars I've owned. This full synthetic oil is absolutely the best in my opinion. Excellent in preventing engine wear, resistant to both over heating and freezing and is very high performance. I owned a Firebird and Camaro. A good plus is that its recyclable. I like that it comes in a 5 quart jug and the jug has 2 handles to grab onto. Also, the price is competitive to other synthetic motor oils. The best!

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. This is another great great product that they make!

[This review was collected as part of a promotion.] I've been changing my own oil for a lot of years now and have always trusted Pennzoil. I have tried other brands before but keep coming back to Pennzoil so far I've been very pleased with Pennzoil full synthetic as always great quality

[This review was collected as part of a promotion.] Ok I've been using Pennzoil for a long time now. Specially the full synthetic. I change my oil between 5k and 7k miles and I've got over 200k miles on the car. I feel like the oil is one of the reasons my car still runs strong.
