[This review was collected as part of a promotion.] I have been using Pennzoil motor oil for many years and have come to trust the brand. I recently added this full synthetic oil to my vehicle and am very confident with the quality. The bottle was easy to pour with no mess.

[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 use the Pennzoil Full Synthetic oil for my F150 super duty and have the bets performance. This oil goes a long way and easy to change out. I used 6- 1 quart bottles. Easy to pour, I seem to never spill when using the little ones.

[This review was collected as part of a promotion.] I changed my oil 11 days ago and replaced with the Penzoil synthetic. I have always used synthetic as my car requires it. Traditionally, I would use the manufacture brand. I did not notice any difference from this brand to the previous. Unfortunately , I am writing this review 11 days after trying. Ideally, if I were able to wait the 5000 miles and then my review would be more comprehensive and complete. So far the oil seems the same as previous .

[This review was collected as part of a promotion.] I take my car's maintenance seriously, and I perform all my own maintenance on my car - that way I know it is done correctly. I always have trusted Pennzoil products - specifically their motor oil products - for my cars because I know they stand up to harsh driving conditions, which my car faces daily. I have kept my cars' engines running without problems for well over 100K miles, and I attribute that to the quality of Pennzoil's motor oils.

[This review was collected as part of a promotion.] This is the best oil that I have used. It is long lasting and my vehicles run great with it. I will not use anything else in my vehicles and I think that their life is extended from using this. I wish I would have switched earlier... Well worth the money.

[This review was collected as part of a promotion.] I got the Pennzoil - Pennzoil Full Synthetic. I got a Dodge Ram Pick up Truck and i do all my own oil changes and this is the only motor oil I would ever use . I would definitely recommend this to anybody looking for a really great motor oil for high mileage vehicle.

[This review was collected as part of a promotion.] I have used many oils on my 2014 Acura and have always consistently found the oil to be dirty during every oil change. But after trying out the Pennzoil synthetic for the car, I can totally see the difference. This is a very good oil and does a great job in keeping all machinery clean. It's definitely a high quality oil that dealers would use. Eventhough I don't need to change oil for a while, I'd love to keep changing every 4-5K miles, to keep the inside machinery clean and running smooth. I'd say this is the best oil you can find for your vehicles that you want to keep running longer, and ones that you drive daily. I'd definitely recommend.
