[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 have been using Pennzoil motor for as long as I can remember. It has always done me good and never had issues with my motors in any of the cars I've owned. This full synthetic oil is absolutely the best in my opinion. Excellent in preventing engine wear, resistant to both over heating and freezing and is very high performance. I owned a Firebird and Camaro. A good plus is that its recyclable. I like that it comes in a 5 quart jug and the jug has 2 handles to grab onto. Also, the price is competitive to other synthetic motor oils. The best!

[This review was collected as part of a promotion.] I've only recently made the switch to using Full Synthetic oil on my SUV and chose Pennzoil. I change my engine oil every 5,000 miles and extremely happy with the performance of my engine after the first oil change to Pennzoil synthetic. The SUV runs smoother and quieter than before. Engine runs smoothly after

[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.

It Cleaner pistons , better fuel economy, protects horsepower, unsurpassed wear protection, excellent performance in extreme temperatures Its was very easy to use in my car I did not get the big 5 gallon jug but six regular sized bottles.

[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.] This Pennzoil Full Synthetic Oil makes my car run great and smooth. It’s your entry level synthetic oil, but Pennzoil does a great job at making a true synthetic oil so you know you are getting the real thing. I like the design of the packaging and the consistency of the oil, it’s a quality product throughout. I highly recommend this oil to anyone looking for a high quality, long lasting synthetic oil for their vehicle.
