[This review was collected as part of a promotion.] This is the best oil that I have used. It is long lasting and my vehicles run great with it. I will not use anything else in my vehicles and I think that their life is extended from using this. I wish I would have switched earlier... Well worth the money.

[This review was collected as part of a promotion.] I switched over to this Pennzoil Full Synthetic oil for my older riding lawn mower. It's better for the engine and I love the fact I have to change it less frequently. My mower seems to run smoother since the switch. Pennzoil is a brand I trust and will continue using. Highly recommended!

[This review was collected as part of a promotion.] We use this oil in our Subaru Forrester 2010, it really helps the engine run smoothly. Our car has over 125K so it does burn some oil, and it is always nice to have this on hand to top off when needed.

[This review was collected as part of a promotion.] I use the Pennzoil Full Synthetic on my Chrysler Town and Country. It’s the only oil I would ever put in my vehicles. It’s the perfect consistency. Pennzoil Full Synthetic Helps me get the most out of mileage for my car. It keeps my van running great and clean with no issues. I can go a lot of miles before I have to do an oil change. I also noticed my car doesn’t burn the oil like it used to with non synthetic. I highly recommend Pennzoil Full Synthetic for a great quality oil.

[This review was collected as part of a promotion.] I’ve been changing my oil for many many years and Pennzoil is my go to oil. This full synthetic oil gives me confidence that it is going to treat my car right and not give me any issues. I’ve trusted Pennzoil for many years and hope to continue for many more to come.

[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 am a huge supporter of the fully synthetic oil. Runs great in my jeep and I have never had an issue with it. I do all my oil changes myself and have been a pennzoil man through and through. Superior product at a superior price!!

[This review was collected as part of a promotion.] I received this a while ago and just did my oil change yesterday. Oil was clean and went in steady. I applied the new filter and only time will tell how my engine runs. So far it seems do be running great!

[This review was collected as part of a promotion.] This full synthetic oil is just like the Review Title says, "Super slick!" My engine runs really smooth with this oil. Obvious benefits of friction reduction of engine components have resulted in a boost in fuel economy. Granted, I don't have a physical/measurement comparison, since I have not taken my engine apart to do so, I'm confident it's doing what it's supposed to do.

[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.
