[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.] If you are like me and do work on vehicles at home like changing oil, adding windshield washer fluids, etc than boy do I have the perfect oil to be used to change yours at home in the comfort of your garage, shop, or even in your driveway or grass. I'm always tinkering with mine and my family's vehicles and one thing I always remember to do is to change the oil as it approaches the mileage recommended. While I've used different brands in the past Pennzoil Full Synthetic is top notch in my book! I get the box containing 6, 1 QT bottles of Pennzoil Full Synthetic 5W-20 which gives your vehicle 40% better performance than conventional motor oil. Although this brand has many varieties this particular one offers not only better fuel economy but it will go longer between oil changes, protection in extreme temperatures, conditions older seals as well as protection against sludge & deposit build up. Those being my main concern with my wife and teenagers driving. It's an amazing feeling knowing this trusted company had any consumers worries to a minimum of not gone completely! I am a repeat Pennzoil purchaser but think I'll continue using this particular one for adding oil to doing the works with helping my family with complete oil changes.

Good price on this oil

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.

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
