Great prize

Loved Penzzoil engine full synthetic oil. Have been using it for years and never had a problem with my 2004 ford Lincoln Navigator. My vehicle takes 7 quarts of oil and buying from Sam’s at this price $32.98 per 6 quarts, I couldn’t let this opportunity passed.

Great Product

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is entry level synthetic oil for people changing from regular oil or blend to full synthetic oil. Pennzoil is great and I always depend on it to keep my vehicle running smoothly

Great Product!

[This review was collected as part of a promotion.] What can I say but Pennzoil has been and always will be my number one choice of oil for all my vehicles! It's always kept my engines running smooth and has never let myself or anyone I know down. I will continue to use it for every vehicle I own.

Works good

[This review was collected as part of a promotion.] I got this pennzoil full synthetic motor oil to try out in my 05 pontiac g6 with 75000 miles, and must say that so far has been a great motor oil. Put about 3500 miles on it since changing the oil and still is pretty clean on the dipstick. Think I may be changing oil brands.

Super slick!

[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.

Quality Oil

[This review was collected as part of a promotion.] I've only recently made the switch to using Full Synthetic oil on my SUV and chose Pennzoil. I change my engine oil every 5,000 miles and extremely happy with the performance of my engine after the first oil change to Pennzoil synthetic. The SUV runs smoother and quieter than before. Engine runs smoothly after

Good motor oil

[This review was collected as part of a promotion.] I recently received this motor oil and glad I did. It seems like the performance in my Jeep is better and it is running smoothly without any sort of performance issues. I’d recommend it to anyone looking to upgrade their oil.

Keeps my older Mini Cooper running like a champ

[This review was collected as part of a promotion.] After some work to get my 2010 Mini Cooper running well again, the mechanic recommended this synthetic. So far, so good. The engine performance has been maintained, running nice and quietly, and I am not losing oil anymore. I have also been able to go to 6 month oil changes instead of 3 month oil changes, which easily offsets the slightly higher price.

Great product

[This review was collected as part of a promotion.] Excellent performance and protection. One of the best in the market, have observed that slight increase in mileage and the car runs smoother. Also last quite longer before oil changes that the other brands. Can't go wrong with this one
