[This review was collected as part of a promotion.] Time and time again, this oil impresses. It holds its lubricating capacity better then most whilst being very affordable. I have worked on cars for 30 years and this is my go to oil. What more could one desire..

[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.] This Pennzoil Full Synthetic Oil is high quality, affordable, and made by the best in the business; Pennzoil! I love the design of the bottle as well for a nice even and smooth pour. The additional handle comes in handy when putting it into the funnel.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic motor oil really is a terrific product this motor oil really helps keep your car running in tip top shape if you haven't already you really need to give Pennzoil a try you will not be disappointed.

[This review was collected as part of a promotion.] As usual great product. I’ve been using Pennzoil for years and this is my first time trying the full synthetic I was hesitant at first because I didn’t know much about synthetic oil. After some research at homework I found out the Pennzoil is one of the top oils in full synthetic. I am completely impressed and amazed by the quality that Pennzoil is presented in this product I highly recommend anyone looking for a full synthetic oil.

[This review was collected as part of a promotion.] I used this pennzoil in my last oil change and it made a big difference in performance and engine noise. It stayed cleaner longer for better protection. I like the convenient 5 quart jug which makes filling up simpler. I would definitely recommend giving this a try specially for the value you get at the price point.

[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.] It is very difficult for the average person to evaluate oil. I do not know the inner workings of engines. But what I can say is that my experience with this Pennzoil Full Synthentic comes with no compaints whatsoever. The bottles are easy to handle, I'll be using this oil for my next oil changes for sure. My car is 11 years old and the engine has been a bit shaky lately, but I used this oil to top off and it's been running smoothly ever since.

[This review was collected as part of a promotion.] Just did my first oil change with the Pennzoil full synthetic. It was straight forward and easy to use. Excited to see how it performs down the road but it’s working as expected so far! No issues with over heating or oil pressure.

[This review was collected as part of a promotion.] I've been changing my own oil for a lot of years now and have always trusted Pennzoil. I have tried other brands before but keep coming back to Pennzoil so far I've been very pleased with Pennzoil full synthetic as always great quality
