[This review was collected as part of a promotion.] Pennzoil Full Synthetic Motor Oil is good quality motor oil that helps keep my engine running smooth. It is better than conventional oil and will allow for fewer oil changes in the future so that is a plus.

[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.] My vehicle is my baby and I am always worried about the products I put in it. Being a mechanic Pennzoil is the product we usually use in the clients vehicles and they have had many good things to say about the brand, so this is what I use for my vehicle and I have had no issues with it! This is great quality and great for you vehicle.

[This review was collected as part of a promotion.] Time and time again, this oil impresses. It holds its lubricating capacity better then most whilst being very affordable. I have worked on cars for 30 years and this is my go to oil. What more could one desire..

[This review was collected as part of a promotion.] I like the fact that it is better for the performance of my car.I also like that is made from synthetic base oils and in its manufacturing converts natural gas into a high quality synthetic base rather than crude. Better fuel economy

[This review was collected as part of a promotion.] These are the perfect oil bottles to use to fill up my lawn equipment with . I have tried using the big jugs and it just makes a big mess all over my garage . I run a lawn business on the side and have multiple pieces of equipment that take 5w-20 full synthetic oil . I've always used the pennzoil oil with my lawn equipment and it's been the best choice . I used these bottles of oil in my weedeaters, edger, hedger, pressure washer and also my generator . This product hasn't failed me yet

[This review was collected as part of a promotion.] I bought this oil for my 2016 civic after learning how to cahnge my car oil myself. We have been using this brand since my cars first oil change at 5k. Never had a problem, never burns or low after 5k hard city driving.
