[This review was collected as part of a promotion.] I recently tried Pennzoil full synthetic 5w20. After I changed my oil and filter I noticed more power during acceleration and less delay in my engine. I highly recommend Pennzoil products to bring your vehicle to life.

[This review was collected as part of a promotion.] It was service time for my Lexus and it requires 5W20. Previously, it would get maybe 16mpg in town and 22 on the road. Average at best. After the change to this synthetic oil, my mileage improved a solid 1 mpg both in town and on the road. Impressive for something so simple.

[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.] 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.] I have used Pennzoil Synthetic motor oi in my vehicles for years. I have had good luck with it. I drive a lot of highway miles at high speeds and I believe that Pennzoil is the best choice for high speeds and longer driving times. I run 8000 miles between changes.

[This review was collected as part of a promotion.] I use this for a multitude of things that uses this oil. It works perfectly in my car. I don't think I have ever had my car run so well before. It seems like it runs smoothly as well. I went on a few trips already out of state and there hasn't been an issue.

[This review was collected as part of a promotion.] Great motor oil! I switched to synthetic on a few of my high mileage vehicles and I’m convinced that Pennzoil has increased the life of them! I know they say you can run longer between oil changes with synthetic but I still change it at 3k. 180k on one of my trucks and still runs like new!!

[This review was collected as part of a promotion.] I have used Pennzoil for years. My dad used Pennzoil in everything when I was little. I got a case of synthetic oil for all of my annual services on all of my small gas engines. I have done all of my preventative maintenance with Pennzoil and never have had a problem.

[This review was collected as part of a promotion.] I use the pennziol product in every piece of equipment I have. Tractors, trucks, boat, chainsaws. I never have to worry about the product. It has been around for many of years. It has changed with the times. I used this product in my pickup truck. The labeling is great the color of the plastic jar is yellow and has been for years, can’t miss it. Thank you to all of your people for it.
