[This review was collected as part of a promotion.] It took me a bit to write the review as I had nothing needing an oil change. But this summer's start of camping season changed that! I really love the double handle option on the bottles, it really makes options for pouring the bottles very easy. As far as performance, I will have to get back after some miles have been put on.

[This review was collected as part of a promotion.] My Porsche loves this synthetic oil, it runs my car smooth and very efficient. It leaves no residue and takes care of my engine. Definitely something to invest in if you want your car to last long and continue to function perfectly

[This review was collected as part of a promotion.] This oil is a good quality oil. I would say my engine has been running a bit smoother since I put this in my car. My car has always been a bit touchy, but since using this I notice it has been a bit more smooth. I won’t go back to my other oil.

[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.] We use this oil in our Subaru Forrester 2010, it really helps the engine run smoothly. Our car has over 125K so it does burn some oil, and it is always nice to have this on hand to top off when needed.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.

[This review was collected as part of a promotion.] I use the pennziol product in every piece of equipment I have. Tractors, trucks, boat, chainsaws. I never have to worry about the product. It has been around for many of years. It has changed with the times. I used this product in my pickup truck. The labeling is great the color of the plastic jar is yellow and has been for years, can’t miss it. Thank you to all of your people for it.

[This review was collected as part of a promotion.] I got this oil for my car because I thought I’d try using synthetic oil and see if it works better than conventional oil. So far, I’m better gas mileage, the engine seems to run a little smoother and I can go twice as far between oil changes. It’s a win win win.

[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.] 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.
