[This review was collected as part of a promotion.] I have been using Pennzoil products for 40+ years without an oil related engine failure. Pennzoil Full Synthetic Oil has kept my vehicles running smooth. This is a good quality oil at a good price. Highly recommend

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is their top of the line oil. I have used it for years and it keeps the engine clean and running great. Meets Chrysler and Ford specs along with many others. 5000 miles between oil changes is no issue!

[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.] If you are like me and do work on vehicles at home like changing oil, adding windshield washer fluids, etc than boy do I have the perfect oil to be used to change yours at home in the comfort of your garage, shop, or even in your driveway or grass. I'm always tinkering with mine and my family's vehicles and one thing I always remember to do is to change the oil as it approaches the mileage recommended. While I've used different brands in the past Pennzoil Full Synthetic is top notch in my book! I get the box containing 6, 1 QT bottles of Pennzoil Full Synthetic 5W-20 which gives your vehicle 40% better performance than conventional motor oil. Although this brand has many varieties this particular one offers not only better fuel economy but it will go longer between oil changes, protection in extreme temperatures, conditions older seals as well as protection against sludge & deposit build up. Those being my main concern with my wife and teenagers driving. It's an amazing feeling knowing this trusted company had any consumers worries to a minimum of not gone completely! I am a repeat Pennzoil purchaser but think I'll continue using this particular one for adding oil to doing the works with helping my family with complete oil changes.

[This review was collected as part of a promotion.] I've only recently made the switch to using Full Synthetic oil on my SUV and chose Pennzoil. I change my engine oil every 5,000 miles and extremely happy with the performance of my engine after the first oil change to Pennzoil synthetic. The SUV runs smoother and quieter than before. Engine runs smoothly after

[This review was collected as part of a promotion.] This is great quality oil that is perfect for my Honda Civic. This oil has my car running very smooth and seems like my engine is running quieter. It seems this oil will keep my engine running great and continue to improve the overall performance of the car.

[This review was collected as part of a promotion.] I've always used oil weight of 5w 30 in my jeeps engine. I was never really picky about the brand of oil I used. As long as it did it's job. I was so wrong. I've been having a few miner issues with the performance of my Jeep. When I talked to my mechanic he said it's your oil, try a different brand. So Pennzoil it was and I'm glad I did. My Jeep engine sounds better. It was quick and easy to change my oil myself and I'm loving the Pennzoil brand. Great performance!

[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.] Penzoil is a premium brand for your car. It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles. This is great for my car that does not have high mileage.

[This review was collected as part of a promotion.] I love my Pennzoil Full Synthetic oil! I use it in all of my vehicles. I used the Pennzoil Full Synthetic 5w 20 in my 2010 Honda Accord and it continues to run like a champ! I change my oil as soon as the "Oil Life" reaches zero and I have not had any engine problems. I am a firm believer that if you change your oil on a regular bases with quality oil, your engine will last you a long time. I have been using Pennzoil in my 2003 SUV and it has 257,000 miles on it and still runs great! I highly recommend Pennzoil!
