[This review was collected as part of a promotion.] Pennzoil helps to keep my Buick on the road. While I'm not that great of a driver to notice every little difference an oil makes, Pennzoil has always been a quality brand. I use the 5W-30 to top off my car if I notice the oil goes below the fill line before I get to my mechanic. It's a Mom N Pop place and you can bring your own oil along for the oil change. I like that this Pennzoil gives me more miles between changes and keeps my engine running smoothly. 

[This review was collected as part of a promotion.] Such a great product from a name you can trust. Now it may cost a little more than your standard oil but the protection it provides for what most people refer to as their prized possession can't be measured in dollars. You just can't get by anymore with just any oil, not with today's cars. The synthetic oil adheres better than conventional oil and in some makes and models its required. So if you're like me you'll stick with a quality product from a name you can trust.

[This review was collected as part of a promotion.] Used this in my last oil change for my Mazda 6 before doing some travel this summer. The car continues to run great, and the oil still looked clean when I checked it after running about 1000 miles in the heat. Oil is a hard to review, because it is one of those things you only pay attention to when it is not working, but I'm happy to report that this full synthetic has worked great for me.

[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.] I have a Lexus ct200h. I can begin to tell when the oil is getting old as the car begins to lag a bit and the mileage is a bit lower. The Pennzoil Full Synthetic did the trick on making the engine run smoother and my mileage has ticked up a bit as well.

[This review was collected as part of a promotion.] Works great had worked great so far for my vehicle I have not had any problems that I can tell It has worked great and I would recommend to anyone that is doing a home oil change and needs a good brand

[This review was collected as part of a promotion.] I got this and I change my oil and use this and so far has given me great miles without any problems. It is a very good oil to use and it is very expensive but it is a very great product. I will definitely recommend this to everyone that i know and i will continue to use this from now on.

[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.] This is a very good oil that produces a very good used oil analysis reports. It appears to do a very good job of keeping the internal clean, And although not designed as a long drain interval oil you can’t push the limit. For instance I’ve went 15,000 miles with a turbo.

[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.
