[This review was collected as part of a promotion.] Excellent performance and protection. One of the best in the market, have observed that slight increase in mileage and the car runs smoother. Also last quite longer before oil changes that the other brands. Can't go wrong with this one

[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.] The Pennzoil Full Synthetic Oil seems to be a great motor oil for my vehicle. The contents of the container is easy to pour into my engine. My vehicle seems to run well. I am impressed with oil because I have never used this oil before.

[This review was collected as part of a promotion.] Works great had worked great so far for my vehicle I have not had any problems that I can tell It has worked great and I would recommend to anyone that is doing a home oil change and needs a good brand

[This review was collected as part of a promotion.] I've used Pennzoil Platinum or Pennzoil Ultra in my 3.6L 2015 Jeep Grand Cherokee & my wife's 2017 Ford Edge since day one. Both vehicles are now over 90,000 miles and run great. The biggest difference I've noticed between this and oils I've used in the past (in other vehicles) is with cold weather starting. With Pennzoil synthetics both of our vehicles start without hesitation or that dry/clunky noise on winter mornings.

[This review was collected as part of a promotion.] Have been running this in my 2014 Wrangler (145k+ miles) since we reached 75k+ and couldn't be happier. Long lifespan and has been great in preventing other engine issues and usually get at least 4,000 miles per oil change

[This review was collected as part of a promotion.] I've relied on Pennzoil Synthetic for years in my vehicles, lawn tractor, and utv. I've never had an issue, oil filters stay clean longer, and engines run smooth. It's easy to pour and my funnel filter is always clean. With regular oil changes, both my vehicles and other equipment are well maintained and last longer - my goal.

[This review was collected as part of a promotion.] This oil is great! After switching to this oil I can tell my engine feels like it runs better and sounds better too also I am getting better MPG now. This will be my go to oil for all my cars. For the price and the benefits, this is a great deal

[This review was collected as part of a promotion.] Ive used Penz for years in my cars. I always appreciate the quality of their product. Especially as they have introduced synthetic. I've gotten out of the habit of changing oil, but my son and I worked on changing his together. A great product!

[This review was collected as part of a promotion.] I am teaching my my some car maintenance and the reason for choosing quality products. He has an older Ranger and since we have been using the Pennzoil Full synthetic in it it has been running smoother. Giving an old truck some new life! I have been using Pennzoil for years and passing it on to a new generation!
