[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.

[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.] I did an at home oil change on my wife's RAV - 4 over the weekend. I tried the Pennzoil Full Synthetic 5W - 20 over my other synthetic choice. I honestly prefer Pennzoil, the weight, color and lack of oil smell was nice so my wife didn't complain. She just drives the car so hasn't noticed any change in the ride or power.

[This review was collected as part of a promotion.] I've relied on Pennzoil Synthetic for years in my vehicles, lawn tractor, and utv. I've never had an issue, oil filters stay clean longer, and engines run smooth. It's easy to pour and my funnel filter is always clean. With regular oil changes, both my vehicles and other equipment are well maintained and last longer - my goal.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is the way to go when you want high quality and a reliable product to keep your vehicle in great shape. It is the best oil out there. It is easy to use. The container itself is made where I have no problems with the oil leaking out of the bottle or anything. The oil is clean and I can tell my vehicle runs smoother. It is also great that I can go longer between oil changes with this full synthetic oil.

[This review was collected as part of a promotion.] My car only takes full synthetic oil so this pennzoil is a great oil for my car. The bottles were easy to open and easy to pour. I am sure I will get the full mileage out of the oil. The bottles can be recycled which is a big plus.

[This review was collected as part of a promotion.] What can I say, great product from a company that is well known and trusted. Feel comfortable knowing this will keep the cadillac running for years to come, great product and packaged well when shipped to my house.

[This review was collected as part of a promotion.] You pay so much for your car, so you definitely want to use the best products for it and this oil is definitely something your engine will thank you for. I've never had any engine issues when using this type of oil and it runs smooth.

[This review was collected as part of a promotion.] I use the Pennzoil Full Synthetic on my Chrysler Town and Country. It’s the only oil I would ever put in my vehicles. It’s the perfect consistency. Pennzoil Full Synthetic Helps me get the most out of mileage for my car. It keeps my van running great and clean with no issues. I can go a lot of miles before I have to do an oil change. I also noticed my car doesn’t burn the oil like it used to with non synthetic. I highly recommend Pennzoil Full Synthetic for a great quality oil.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic 5w30 case of 6 is very convenient and a bit cheaper to buy than buying 6 individual. We have several vehicles so need to buy a lot of oil. Best oil we've bought in a while its quality is superb
