[This review was collected as part of a promotion.] My Porsche loves this synthetic oil, it runs my car smooth and very efficient. It leaves no residue and takes care of my engine. Definitely something to invest in if you want your car to last long and continue to function perfectly

[This review was collected as part of a promotion.] We all know Pennzoil stands by their name. I will not go with any other brand. The price is more than worth it. I feel like If I can trust this brand so can everyone else. Please spend the extra amount on Pennzoil it is more than worth it.

[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 have used many different brands of synthetic oils but using Pennzoil it's the one brand that performs best! Top quality oil that helps to protect your engines and make them run quieter and smoothly. Engines starts up on the first go whether it's in cold or warm weather. Use in engines big or small. It's trusted to protect and perform incredibly well! Highly recommended as you will not be disappointed!!

[This review was collected as part of a promotion.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

[This review was collected as part of a promotion.] I desperately needed oil for my truck and I only use synthetic so this couldn’t have come at a better time. And I Already tell a difference in performance. Pen soil is awesome!! My truck purrs like a kitten

[This review was collected as part of a promotion.] I love this brand of oil, especially the full synthetic type. Use this in my 14 Edge and go for 10,000 miles. I've used many different brands over the years, but always go back to Penzoil for it's quality and availability.

[This review was collected as part of a promotion.] I did an at home oil change on my wife's RAV - 4 over the weekend. I tried the Pennzoil Full Synthetic 5W - 20 over my other synthetic choice. I honestly prefer Pennzoil, the weight, color and lack of oil smell was nice so my wife didn't complain. She just drives the car so hasn't noticed any change in the ride or power.
