[This review was collected as part of a promotion.] I have a late model GMC Yukon XL. Runs great but burns oil more than it used to. I like keeping this around to top off every now and then. Full Synthetic is my choice for extra protection for the high mileage engine.

Dump the old and refill the life juice of your engine with this great stuff. came out looking like it went in. its a great reliable choice for all performance machines.

[This review was collected as part of a promotion.] I drive a 2008 and it has some issues, so I like to use full synthetic oil instead of conventional oil. The full synthetic oil I feel is just a better oil for my car. I feel it lasts longer and just is all around better. I use the same for my daughter's 2001. And Pennzoil is my preferred brand.

[This review was collected as part of a promotion.] Pennzoil is the only brand oil i use in my Ford f150. Pennzoil full synthetic oil last a lot longer than almost all other brands of oil. It also makes my truck run smooth and helps the engine run better. I highly recommend this oil.

[This review was collected as part of a promotion.] Great motor oil! I switched to synthetic on a few of my high mileage vehicles and I’m convinced that Pennzoil has increased the life of them! I know they say you can run longer between oil changes with synthetic but I still change it at 3k. 180k on one of my trucks and still runs like new!!

[This review was collected as part of a promotion.] Used Pennzoil full synthetic 5w-20 at my last change, replacing another brand. I run synthetic in my 2007 Chrysler Pacifica and this Pennzoil is doing just fine after nearly a thousand miles run on it. Seems to do better on it than the previous brand, which was already a huge improvement over conventional oil.

[This review was collected as part of a promotion.] This works great for my car. I followed the instructions and saw some videos to see how to use and followed accordingly and I was happy that it works well for my engine. Full synthetic and great quality. I used it for my 2010 Toyota Corolla and my car is running smoothly.

[This review was collected as part of a promotion.] I love this Pennzoil oil. I have used thier products in all the vehicles I have owned. I have never had an oil related break down. This is a very good synthetic oil. It seems they just keep getting better wirh every new product they make.

[This review was collected as part of a promotion.] When it comes to adding life to your engine the one single thing you can do is keep the oil changed! Oil is the life of your engine regardless if it’s your automobile or your lawnmower. This Pennzoil full synthetic is a great oil and is 100% synthetic that provides better fuel economy and great wear protection. I highly recommend this oil.
