[This review was collected as part of a promotion.] Pennzoil full synthetic oil works great for my truck. I just did an oil change with it and my motor seems to run smoothly. It is greatly priced and it can be used in my boat, vehicle and my lawnmower which is amazing. It is a trusted repeatable company that I trust. It is alway good to keep an extra in the car. I used a different brand previously but I will be sticking to Pennzoil strictly!

[This review was collected as part of a promotion.] This works great for my car. I followed the instructions and saw some videos to see how to use and followed accordingly and I was happy that it works well for my engine. Full synthetic and great quality. I used it for my 2010 Toyota Corolla and my car is running smoothly.

[This review was collected as part of a promotion.] Used this in my last oil change for my Mazda 6 before doing some travel this summer. The car continues to run great, and the oil still looked clean when I checked it after running about 1000 miles in the heat. Oil is a hard to review, because it is one of those things you only pay attention to when it is not working, but I'm happy to report that this full synthetic has worked great for me.

[This review was collected as part of a promotion.] Put this stuff in your vehicle and you won't have to worry about it for 7,000 or 8,000 miles. Great value, and cheaper than at any of the auto parts places. Numerous oil tests on BITOG will confirm, this stuff is one of the best performing synthetic oils available, and the price is great. This one always does well, very little burns off - and it comes out still in pretty good shape. Honestly can't think of a good reason not to buy this oil.

I just brought this product today and changed the oil in my 2018 Mazda CX-5 sport. It’s my first time using pennzoil especially full synthetic. Let’s see how it ride and how fast the gas burns

good oil to use in newer cars up to date tech.full synthetic is the way to go keep all parts clean and working grate. I use it in my2017 jeep wrangler with 85000 miles hard miles still runs like new.

20 below zero F in the Rockies or 115 in Palm Springs in July, synthetic provides great protection and smooth quiet engine performance. 0W-20 in 2015 jeep Renegade with 2.4 L 4 cyl engine.

Pennzoil and Quaker State only products now I use.
