[This review was collected as part of a promotion.] Got this about a week ago to change the oil in my mom's car. Figured I had a little time, so why not do it myself? Use to do it all the time. Well, cars have changed since then, and it wasn't such an easy job anymore. Had to get some help...called in a mechanic friend to finish the job, and he and I both noticed the Pennzoil Full Synthetic has received excellent marks for durability and protection. It might be wishful thinking, but mom's car seems to be running better, just with the Pennzoil oil change added. Think I'll be changing all my cars to this product soon!!!

[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.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.

[This review was collected as part of a promotion.] Great product. Works great in my car. No issues. Lasts long time. Only product I use in my cars. Cara always run great with it. Never had any issues with either vehicle using this product. My wide won't use anything else.

[This review was collected as part of a promotion.] This is a great oil. I have used it on foreign and domestic cars with over 100,000 miles. Always last long and a good choice overall. I will definitely continue using pennzoil products in the future..

[This review was collected as part of a promotion.] I've always used synthetic oils in all my cars for the extended oil change interval and better protection against viscosity breakdown. The Pennzoil Full Synthetic is just as good as any of the more expensive options like Mobil-1 or Castrol. Oil changes are a great way to keep a car running for a long time and with this oil, I'm not worried about being a few hundred or even a thousand miles late for an oil change.

[This review was collected as part of a promotion.] I got this and I change my oil and use this and so far has given me great miles without any problems. It is a very good oil to use and it is very expensive but it is a very great product. I will definitely recommend this to everyone that i know and i will continue to use this from now on.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic is all I use on my vehicles. I have a Jeep and of course I change my own oil. I love how easy this is to use and the quality it provides to my vehicle. My Jeep is running smoothly.

[This review was collected as part of a promotion.] I have a 2006 F-150 with 175000 miles and I want it to make it 500000! This is the only brand and type of oil I use in my truck and trust Penzoil over any other brand. My truck alwasy runs smoother, cleaner and gets better gas mileage with Penzoil. Whether you do a DIY oil change or not - this is the oil to go with here guys

[This review was collected as part of a promotion.] This oil is the best you can get, at least one that is affordable. It cleans, protects, and lubricates very well. Shake the oil before adding to get all the detergent out, because it may have settled. Pennzoil offsets 100% of the carbon emissions from creating the oil.
