[This review was collected as part of a promotion.] I have used Pennzoil Synthetic motor oi in my vehicles for years. I have had good luck with it. I drive a lot of highway miles at high speeds and I believe that Pennzoil is the best choice for high speeds and longer driving times. I run 8000 miles between changes.

[This review was collected as part of a promotion.] I love Pennzoil. I like the fact that it is made well without contaminants in the oil like regular base stock mineral oil. Works great and all the applications that I used it in for my jeep wrangler and suabru. I've found that cars I've used other oil on have had engine troubles, while I can prove a correlation I do believe this to be related.

[This review was collected as part of a promotion.] While its hard to notice a difference between various oils, I "feel" like the Pennzoil synthetic makes the car run quieter. The difference is very small but I do feel like I notice a difference when I use it. It does pour out very easy and doesn't spill too bad. I highly recommend Pennzoil Synthetic oil!

[This review was collected as part of a promotion.] This oil is the best you can get, at least one that is affordable. It cleans, protects, and lubricates very well. Shake the oil before adding to get all the detergent out, because it may have settled. Pennzoil offsets 100% of the carbon emissions from creating the oil.

[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.

[This review was collected as part of a promotion.] I always get Pennzoil for my car. I have to get the full synthetic since my car is foreign. Got this to do my own oil change and my car runs great. My car is getting higher in miles so will have to go with higher mileage oil next time.

[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 am a huge supporter of the fully synthetic oil. Runs great in my jeep and I have never had an issue with it. I do all my oil changes myself and have been a pennzoil man through and through. Superior product at a superior price!!

[This review was collected as part of a promotion.] We needed a Full Synthetic Oil that would work on our vehicle to keep it running in top notch condition. The synthetic oil by Pennzoil is a great value for our cars. It has the right amount of additives to insure that your car is running at its best condition oil wise. It is easy to pour and the handle is easy to grip and carry. The container is also easy to store while not in use.

[This review was collected as part of a promotion.] I received this oil last month . I really love brand of oil. I love it’s synthetic which I use in all my vehicles since they all have high milage. I really like this brand and will be using this from now on’.
