[This review was collected as part of a promotion.] Pennzoil - Pennzoil Full Synthetic is a high quality oil. I’m currently using it in my high mileage suv and so far all has been well. I’m looking forward to seeing my engine run well and the benefits from using this oil.

[This review was collected as part of a promotion.] Pennzoil is by far the best engine oil I’ve used so far. I feel much better putting this oil in my car. I’ve gotten great performance from my car. The engine sounds great and runs smoothly. This is a great oil for my car.

[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.] This full synthetic oil is made from natural gas and not crude oil. It helps to achieve better fuel economy. It also helps to keep the vehicle's piston clean. Overall a very well made product for your vehicle and highly recommended.

[This review was collected as part of a promotion.] Protection of my car is my most important thing. I always need the best. Since switching to full synthetic I always go with this brand. I always change my oil as well. So I know it is done right and done well. My car runs better with this oil. I am thrilled with it.

[This review was collected as part of a promotion.] Time and time again, this oil impresses. It holds its lubricating capacity better then most whilst being very affordable. I have worked on cars for 30 years and this is my go to oil. What more could one desire..

[This review was collected as part of a promotion.] I decided to use this in my 95 explorer since it has trouble with dry start and I can say this definitely helped out during the heated days. Oil seems to keep the same protection as 5w20 but flows much easier for that old oil pump. I’d definitely recommend this to anyone having a slight lifter tick.

[This review was collected as part of a promotion.] I have used different brands of oil in my vehicles over the years but the brand I keep coming back to is Pennzoil. Their full synthetic oil keeps my engine running smooth and I seem to get better fuel economy with it. I'll keep using the brand I trust.

[This review was collected as part of a promotion.] I recently received this motor oil and glad I did. It seems like the performance in my Jeep is better and it is running smoothly without any sort of performance issues. I’d recommend it to anyone looking to upgrade their oil.
