[This review was collected as part of a promotion.] I used this pennzoil in my last oil change and it made a big difference in performance and engine noise. It stayed cleaner longer for better protection. I like the convenient 5 quart jug which makes filling up simpler. I would definitely recommend giving this a try specially for the value you get at the price point.

[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 use and will continue to use full synthetic in all of my had run engines. Those are all my small engines and my SUV with the turbo on it. Anything that is labeled eco-boost or has a "t" in the model name has a turbo in it and probably already calls for it. Pennzoil has never let me down and I'll continue to use it.

[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.

[This review was collected as part of a promotion.] Pennzoil is a brand that I have always admired. I use it with the confidence because quality is in it's name. There are many brands to chose from but you will never go wrong using Pennzoil Synthetic. It's a name that's been around a long time and you can trust that.

[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 used this to change the oil in my truck with over 2000 thousand miles. Had no problems with it at all. Drove it about a week. And check it and it looked nice and clean. Will definitely be using for my vehicles from now one.

[This review was collected as part of a promotion.] I have used Pennzoil for years. My dad used Pennzoil in everything when I was little. I got a case of synthetic oil for all of my annual services on all of my small gas engines. I have done all of my preventative maintenance with Pennzoil and never have had a problem.

[This review was collected as part of a promotion.] I recently received this motor oil and glad I did. It seems like the performance in my Jeep is better and it is running smoothly without any sort of performance issues. I’d recommend it to anyone looking to upgrade their oil.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is the best oil ant the best price. It keeps my engine running smooth and the great anti-wear additives keep things slick and in good shape. Tip: I always give the container a really good mix before putting it in my car because of the separation of the ingredients - that way all the good stuff is together.
