[This review was collected as part of a promotion.] I love this Pennzoil oil. I have used thier products in all the vehicles I have owned. I have never had an oil related break down. This is a very good synthetic oil. It seems they just keep getting better wirh every new product they make.

[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.

Oil is the life of your engine regardless if it’s your automobile or your lawnmower. This Pennzoil full synthetic is a great oil and is 100% synthetic that provides better fuel economy and great wear protection. I highly recommend this oil.

[This review was collected as part of a promotion.] This is my first time using full synthetic oil and I wouldn’t do it with any other company than Pennzoil. My buddy has been trying to get me to do this for several years but I have been stubborn. I finally decided to give it a shot and put the Pennzoil Full Synthetic in my truck. I have seen a difference already in the way my engine runs. I took it on a 4 hour drive and it was smooth as it was the day I bought it. I am looking to get an extended period on the full synthetic. I will continue to monitor this over the mileage. This oil was packaged in nice quart size individual packaging. Easy to pour and easy to grip. I am currently satisfied and would recommend this oil to anyone looking for a full synthetic oil.,

[This review was collected as part of a promotion.] After replacing the engine oil in both my generator and lawnmower with this brand of oil the engine sounded smooth and run like a charm and this was the first time for me of ever using this brand of oil and in my opinion this engine oil is of the greatest quality of oil on the market.

[This review was collected as part of a promotion.] I've always used synthetic oils in all my cars for the extended oil change interval and better protection against viscosity breakdown. The Pennzoil Full Synthetic is just as good as any of the more expensive options like Mobil-1 or Castrol. Oil changes are a great way to keep a car running for a long time and with this oil, I'm not worried about being a few hundred or even a thousand miles late for an oil change.
