[This review was collected as part of a promotion.] I bought the Pennzoil full Synthetic to put oil in my truck . It works great and it has good quality. It is a very good oil to use. You can also it use it in your lawnmower and weed eater and like I said it works great.

[This review was collected as part of a promotion.] I prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.

[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.

[This review was collected as part of a promotion.] The Penzoil Full Synthetic Oil OW-20 is for people changing from typical oil to full synthetic engine oil for a smooth switch. I found this oil to be very effective and it really helped my car to run super smooth and provided the most efficient oil crossover possible. This Pennzoil product is for gasoline engines only and provides 40% better performance than conventional motor oil. It comes in a 1 qt container with a twist off top for easy pouring and even has a clear vertical line for precise measuring. I have found confidence in this product and brand and I will definitely be using it in the future.

[This review was collected as part of a promotion.] Full synthetic is great for my wife's car. Got these to keep in her trunk, she gets paranoid when her oil goes below 15 percent so she can keep this for those days. Until I can get around to doing the oil change.

[This review was collected as part of a promotion.] My car uses full synthetic or semi synthetic 5w20. I have never tried pennzoil before. Generally whatever the dealership puts in my car. But so far so good with pennzoil. I have used them in the past with conventional oil but not synthetic until now. So far I am very pleased with the product and their price point.

[This review was collected as part of a promotion.] It's a great full synthetic oil from a brand you can trust. So, the results are perfect, as expected! Great packaging for the shipping, impressive results! This oil will keep my car's engine running nice and smooth for the years to come.

[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.
