[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.] I like the fact that it is better for the performance of my car.I also like that is made from synthetic base oils and in its manufacturing converts natural gas into a high quality synthetic base rather than crude. Better fuel economy

[This review was collected as part of a promotion.] After using this motor oil, I’m extremely impressed! The first thing I love about this oil is how well it maintains my engine’s performance. Ever since I put this oil into my vehicle, I’ve noticed improved gas mileage and have experienced nothing but smooth rides. My engine has also been able to maintain a consistent level of power during “intense activity” (such as driving up hills or mountains). Additionally, I really appreciate how smoothly the oil flows out of the container. It’s easy to fill my vehicle with the oil using this container’s convenient design. The size of the bottle is also perfect for occasionally topping off my oil levels. Overall, I’m extremely impressed with this oil and would recommend it to anyone in search of a high-performance oil that is sure to help your car live a long life!

[This review was collected as part of a promotion.] After so many years of paying the shops to change my oil, I decided to start doing it myself. Pennzoil was my first go to since all my mechanic friends raved about it. I changed the oil as normal and decided to wait and use it for a little bit of time before writing my own review. The quality of the oil is very high. It runs cleaner and I can tell the difference in my vehicles after changing from the oils the shops use. There is an additive that is used in the oil. I did notice that if I did not shake the bottle well enough, there was additive at the bottom (you can see the difference in texture when pouring). I will never take my cars back to the shop again for an oil change and I will always use Pennzoil!

[This review was collected as part of a promotion.] I have been using the Pennzoil full synthetic for my car and it is the absolute best It gives my car full protection for those critical engines’ parts. With Pennzoil full synthetic, you will need fewer oil changes that a conventional motor oil. It comes with enhanced wear protection for high and low temperate. I have noticed my engines runs more smoothly and the car feels like and drive new. The Pennzoil helps present sludge and deposit build up. I use this oil up to 10k miles and then do another change. I trust a name like Pennzoil for my engine and I never do an oil change without it.

[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.] I’ve always used penzoil and bought my daughter a car a few months back and figured I’d try the synthetic this time. It’s a fantastic product and will protect my daughters car for miles to come and put my mind at ease.

[This review was collected as part of a promotion.] Pennzoil® Full Synthetic engine oil is a full engineered engine oil that is appropriate for use in new and more established motors. It is detailed to give 40% preferable execution over traditional engine oil1 and permits less oil changes contrasted with customary engine oil. Along these lines, if your vehicle as of now requires full engineered, or in case you're hoping to update from traditional or manufactured mix Pennzoil® Full Synthetic is the correct decision for you.

[This review was collected as part of a promotion.] Full synthetic is great for my wife's car. Got these to keep in her trunk, she gets paranoid when her oil goes below 15 percent so she can keep this for those days. Until I can get around to doing the oil change.

[This review was collected as part of a promotion.] This oil is great! After switching to this oil I can tell my engine feels like it runs better and sounds better too also I am getting better MPG now. This will be my go to oil for all my cars. For the price and the benefits, this is a great deal
