[This review was collected as part of a promotion.] There are few things in the world that I will buy name brand but motor oil is definitely one of them. When it comes to the care of my car and the safety of my family when we're out driving I trust Pennzoil. Their track record of quality over the years has stayed true and all my cars hav never had so much as a knock or ping even if I haven't changed my oil quite as often as I should have.

[This review was collected as part of a promotion.] I started using pennzoils full synthetic oil on both my trucks about a year ago. Long lasting...I typically go about 7,500 miles between oil changes and the oil still looks good when I drain it. Could probably go another 7,500. Not all oils are of the highest quality as pennzoil

[This review was collected as part of a promotion.] This full synthetic oil is just like the Review Title says, "Super slick!" My engine runs really smooth with this oil. Obvious benefits of friction reduction of engine components have resulted in a boost in fuel economy. Granted, I don't have a physical/measurement comparison, since I have not taken my engine apart to do so, I'm confident it's doing what it's supposed to do.

[This review was collected as part of a promotion.] Pennzoil® Full Synthetic engine oil is a full engineered engine oil that is appropriate for use in new and more established motors. It is detailed to give 40% preferable execution over traditional engine oil1 and permits less oil changes contrasted with customary engine oil. Along these lines, if your vehicle as of now requires full engineered, or in case you're hoping to update from traditional or manufactured mix Pennzoil® Full Synthetic is the correct decision for you.

[This review was collected as part of a promotion.] Pennzoil is a fantastic product, very high quality oil that you can put into your car and then have a lot of confidence it will do its job. Love the full synthetic as well as it allows for longer times between changes saving precious time. Solid oil and company.

[This review was collected as part of a promotion.] Recently did an oil change and my thought always was that all oils are the same. I was wrong. My car was actually quieter and burned less of the Pennzoil than my previous brand. Seems to last longer also as I checked my oil and it was not black or dark as usual. Very pleased and will be using Pennzoil in all my cars for now on

[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 bought this oil for my 2016 civic after learning how to cahnge my car oil myself. We have been using this brand since my cars first oil change at 5k. Never had a problem, never burns or low after 5k hard city driving.

[This review was collected as part of a promotion.] I have used many different brands of synthetic oils but using Pennzoil it's the one brand that performs best!

It's trusted to protect and perform incredibly well! Highly recommended as you will not be disappointed!!

[This review was collected as part of a promotion.] I switched over to this Pennzoil Full Synthetic oil for my older riding lawn mower. It's better for the engine and I love the fact I have to change it less frequently. My mower seems to run smoother since the switch. Pennzoil is a brand I trust and will continue using. Highly recommended!
