[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.] I have used many different brands of synthetic oils but using Pennzoil it's the one brand that performs best! Top quality oil that helps to protect your engines and make them run quieter and smoothly. Engines starts up on the first go whether it's in cold or warm weather. Use in engines big or small. It's trusted to protect and perform incredibly well! Highly recommended as you will not be disappointed!!

[This review was collected as part of a promotion.] I used this for an oil change recently. As far as adding this oil it poured well and as far as oil goes it had a good color to it definitely a quality oil. So far seems to be working well. First time I have used pennzoil and I'm a fan.

[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.] 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 switched to this after using a competitor's full synthetic, and have noticed a difference in my higher milage car. The idle is significantly smoother, as well as engine noise has been reduced. I'm looking forward to harsher driving conditions this summer due to additional heat to put it to the test, but as of now, I have no worries its up to the challenge!

[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.] I used this to change the oil at home in my car and had no problems using it. The jug has two areas you can use as handles which is nice so you can tilt it all the way to get it all poured out. It has my car running great just like it should.

[This review was collected as part of a promotion.] Got this about a week ago to change the oil in my mom's car. Figured I had a little time, so why not do it myself? Use to do it all the time. Well, cars have changed since then, and it wasn't such an easy job anymore. Had to get some help...called in a mechanic friend to finish the job, and he and I both noticed the Pennzoil Full Synthetic has received excellent marks for durability and protection. It might be wishful thinking, but mom's car seems to be running better, just with the Pennzoil oil change added. Think I'll be changing all my cars to this product soon!!!

[This review was collected as part of a promotion.] This is great quality oil that is perfect for my Honda Civic. This oil has my car running very smooth and seems like my engine is running quieter. It seems this oil will keep my engine running great and continue to improve the overall performance of the car.
