[This review was collected as part of a promotion.] Excellent performance and protection. One of the best in the market, have observed that slight increase in mileage and the car runs smoother. Also last quite longer before oil changes that the other brands. Can't go wrong with this one

[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.] 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 got 6 quarts of Pennzoil Full Synthetic. I changed the oil in my car and used this for the replacement. I don't know if this is possible but after about 10days of use I truly think I am getting better gas milage. The car runs quieter than before. This is a good product and everyone should be using a synthetic in their car.

[This review was collected as part of a promotion.] I bought the Pennzoil full Synthetic to put oil in my truck . It works great and it has good quality. It is a very good oil to use. You can also it use it in your lawnmower and weed eater and like I said it works great.

[This review was collected as part of a promotion.] This stuff does just what I need. The bottles are well packaged to prevent spillage, easy to pour from, and I have every reason to believe that the oil itself is of top quality. I can’t really say for sure as testing oil would take a very long time, but the car runs great and I have not seen any sort of accelerated oil leakage or burning. Would buy again!

[This review was collected as part of a promotion.] My Porsche loves this synthetic oil, it runs my car smooth and very efficient. It leaves no residue and takes care of my engine. Definitely something to invest in if you want your car to last long and continue to function perfectly

[This review was collected as part of a promotion.] I received this oil last month . I really love brand of oil. I love it’s synthetic which I use in all my vehicles since they all have high milage. I really like this brand and will be using this from now on’.

[This review was collected as part of a promotion.] I prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.

[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.
