[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.

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.

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.

Pennzoil and Quaker State only products now I use.
