[This review was collected as part of a promotion.] This is a really good brand of oil. I was honestly surprised how much came in the box. I haven't had to use it just yet but I have bought this kind before and never had an issue. Will definitely get more when the times come and would recommend to anyone.

[This review was collected as part of a promotion.] I used this to change the oil at home in my car and had no problems using it. The jug has two areas you can use as handles which is nice so you can tilt it all the way to get it all poured out. It has my car running great just like it should.

[This review was collected as part of a promotion.] What can I say, great product from a company that is well known and trusted. Feel comfortable knowing this will keep the cadillac running for years to come, great product and packaged well when shipped to my house.

[This review was collected as part of a promotion.] I often find myself helping family out with oil changes at my place. I always like to have some on hand and went for this. Absolutely great quality for the price. I now keep this available in my garage all the Time. I do recommend

[This review was collected as part of a promotion.] It was service time for my Lexus and it requires 5W20. Previously, it would get maybe 16mpg in town and 22 on the road. Average at best. After the change to this synthetic oil, my mileage improved a solid 1 mpg both in town and on the road. Impressive for something so simple.

[This review was collected as part of a promotion.] I love this Pennzoil oil. I have used thier products in all the vehicles I have owned. I have never had an oil related break down. This is a very good synthetic oil. It seems they just keep getting better wirh every new product they make.

[This review was collected as part of a promotion.] Pennzoil full synthetic oil is awesome!! My car responded very well to the Pennzoil full synthetic on this recent oil change. I could tell a big difference in how she sounds and runs since changing the oil. This has to be one of the best synthetic blends on the market. My car has never responded so well in all my oil changes. Improved gas mileage for one is a big plus and a smoother ride all together. Many people don't realize that the quality of oil is important and Pennzoil outshines the rest. I am definitely using Pennzoil full synthetic again on my next oil change.

[This review was collected as part of a promotion.] I've always used synthetic oils in all my cars for the extended oil change interval and better protection against viscosity breakdown. The Pennzoil Full Synthetic is just as good as any of the more expensive options like Mobil-1 or Castrol. Oil changes are a great way to keep a car running for a long time and with this oil, I'm not worried about being a few hundred or even a thousand miles late for an oil change.
