[This review was collected as part of a promotion.] As a long-time customer of Pennzoil, I value the quality and consistency of their full synthetics to keep my motor clean and running. This product is up to par with the Pennzoil I've used in the past, and I wouldn't expect anything less! A great American company putting out quality products!

[This review was collected as part of a promotion.] I've been using Pennzoil oil for a very long time. And now that our Honda is getting a bit up there in age and wear, I decided I wanted to transition to synthetic oil. Since I e made the transition, I've noticed a slight increase in fuel efficiency and how the engine runs. I'm excited to see how well it performs as the year goes on, but I know I can always trust Pennzoil, so I'm expecting solid results!

[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.] As usual great product. I’ve been using Pennzoil for years and this is my first time trying the full synthetic I was hesitant at first because I didn’t know much about synthetic oil. After some research at homework I found out the Pennzoil is one of the top oils in full synthetic. I am completely impressed and amazed by the quality that Pennzoil is presented in this product I highly recommend anyone looking for a full synthetic oil.

[This review was collected as part of a promotion.] I used Pennzoil full synthetic in my generator and noticed how the generator ran more smoothly. The bottle design allows for easy pouring and transferring it out of container. Overall, a quality product.

[This review was collected as part of a promotion.] I got the Pennzoil Full Synthetic 5w-20. If you change your own oil this is the oil for you. Pennzoil Full Synthetic motor oil is made from natural gas which makes it much more pure than oil made from crude. It is proven to provide better protection and lasts longer than oil made from crude. Compared to other oil Pennzoil works great on my 2008 Dodge Ram pickup with high mileage .I would definitely recommend.

[This review was collected as part of a promotion.] I have always used Pennzoil products in all of my engines. When I recently purchased a newer car, I had the chance to run the full synthetic. Now I have changed over to the full synthetic in every application possible. This stuff is the good stuff! Great bottles with easy to open/pour packaging.

[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.] Pennzoil is by far the best engine oil I’ve used so far. I feel much better putting this oil in my car. I’ve gotten great performance from my car. The engine sounds great and runs smoothly. This is a great oil for my car.

[This review was collected as part of a promotion.] It took me a bit to write the review as I had nothing needing an oil change. But this summer's start of camping season changed that! I really love the double handle option on the bottles, it really makes options for pouring the bottles very easy. As far as performance, I will have to get back after some miles have been put on.
