[This review was collected as part of a promotion.] It took me a bit to write the review as I had nothing needing an oil change. But this summer's start of camping season changed that! I really love the double handle option on the bottles, it really makes options for pouring the bottles very easy. As far as performance, I will have to get back after some miles have been put on.

[This review was collected as part of a promotion.] I exclusively use Pennzoil for my car, and it hasn't let me down yet. The engine performs the same or better in this than with the oil recommended by the manufacturer; the Pennzoil almost makes the engine "purr" softly when idle. From what I've read in studies of different oil manufacturers by independent third parties, Pennzoil is in the top 3-4 overall oils when it comes to engine wear, how clean it keeps the engine, and resistance to breakdown. In other words, it appears to be exceptional value for the quality of the oil.

[This review was collected as part of a promotion.] One of the best oils I have used in my vehicle. I’ve had no issues at all while using this oil. My vehicle runs great. I haven’t had any engine issues. My vehicle runs smoother and it doesn’t skip or anything. This is just one of those brands you can trust. I definitely will recommend this oil and always use it I’m very satisfied.

[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.] I received this product for a honest review. This is really good oil. I used it in my car and I noticed how much better it runs for me. I change my oil regularly and will continue to use this oil. Easy to use and pour. Works great!

[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'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.] This Pennzoil full synthetic is awesome! This is definitely the best oil I have used by far. This is a must have for anyone and any vehicle. I recieved this as a sample and this is 100% my own opinion!

[This review was collected as part of a promotion.] I recently received the Pennzoil Full Synthetic motor oil and immediately noticed a difference in the way my vehicle ran after use. The oil, which is certified by the American Petroleum Institute, allows my car to run longer between oil changes and increased the fuel efficiency. Over time, choosing full synthetic compared to regular motor oil will save you plenty of money. I have even noticed a difference in the way my car drives, most likely based on the advantages this oil provides to my engine. I would highly recommend this motor oil, especially to anyone looking to protect their vehicle while also saving money in the long run.

[This review was collected as part of a promotion.] Since 1913 Pennzoil has been a true and trusted product for autos. And they've continued caring for our cars and trucks by coming up with a full synthetic oil that not only better protects our engines, it also outlasts regular oil allowing more miles between oil changes. It's a great product for my car which has over 200,000 miles, and is still going strong.
