[This review was collected as part of a promotion.] Protection of my car is my most important thing. I always need the best. Since switching to full synthetic I always go with this brand. I always change my oil as well. So I know it is done right and done well. My car runs better with this oil. I am thrilled with it.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is the best oil ant the best price. It keeps my engine running smooth and the great anti-wear additives keep things slick and in good shape. Tip: I always give the container a really good mix before putting it in my car because of the separation of the ingredients - that way all the good stuff is together.

[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 received this product for a honest review. This is really good oil. I used it in my car and I noticed how much better it runs for me. I change my oil regularly and will continue to use this oil. Easy to use and pour. Works great!

[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.] Pennzoil Full Synthetic is the only motor oil I use in my cars simply because the brand’s oil provides superior protection for your engine and enhances its performance. What’s more, the oil removes all impurities in your engine by loosening the dirt and grime stuck between the moving parts of your engine. This allows for a smoother drive and cleaner engine that performs optimally for longer. We especially love the price because synthetic oil can be pricey. Pennzoil synthetic oil is affordable and more accessible and budget-friendly to consumers.

[This review was collected as part of a promotion.] I recently received this motor oil and glad I did. It seems like the performance in my Jeep is better and it is running smoothly without any sort of performance issues. I’d recommend it to anyone looking to upgrade their oil.

[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!
