[This review was collected as part of a promotion.] I have been using Pennzoil motor oil for many years and have come to trust the brand. I recently added this full synthetic oil to my vehicle and am very confident with the quality. The bottle was easy to pour with no mess.

[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.

[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.] Had no problems with this Pennzoil Full Synthetic oil. Used it to change my oil. Easy to open and close. Easy to use. Comes out great. My van runs nice. I would recommend this product to all my friends.

[This review was collected as part of a promotion.] I’ve always used penzoil and bought my daughter a car a few months back and figured I’d try the synthetic this time. It’s a fantastic product and will protect my daughters car for miles to come and put my mind at ease.

[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 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 recently purchased some Pennzoil Full Synthetic Motor Oil. This oil is very reliable to use since it is manufactured by Pennzoil. This company has been around for many years, I know because I used it when I was a kid and that's been a long time ago. The use of this oil allows you to go many more miles between oil changes. The full synthetic oil is manufactured from natural gas which is very good for emissions and is readily available. It meets all gasoline engine manufacture's requirements. I thoroughly recommend this motor oil.
