[This review was collected as part of a promotion.] Pennzoil full synthetic oil is top quality. took the oil to my mechanic to do an oil change for me. He said that I got the "right stuff" and that Pennzoil is what he recommends. My car is running great and I am very happy with everything.

[This review was collected as part of a promotion.] This motor oil works great for my car. I used it for an oil change and had no problems. I also love the handles which makes it easy to carry. The scent is overpowering but its to be expected with motor oil

[This review was collected as part of a promotion.] Ok, maybe 'life-blood' is a little bit of an exaggeration. It is true, however, that your engine relies on lubrication so all those metal parts move freely and your investment(vehicle) gets you from A to B.

[This review was collected as part of a promotion.] I changed my oil 11 days ago and replaced with the Penzoil synthetic. I have always used synthetic as my car requires it. Traditionally, I would use the manufacture brand. I did not notice any difference from this brand to the previous. Unfortunately , I am writing this review 11 days after trying. Ideally, if I were able to wait the 5000 miles and then my review would be more comprehensive and complete. So far the oil seems the same as previous .

[This review was collected as part of a promotion.] My car only takes full synthetic oil so this pennzoil is a great oil for my car. The bottles were easy to open and easy to pour. I am sure I will get the full mileage out of the oil. The bottles can be recycled which is a big plus.
