[This review was collected as part of a promotion.] I've always used oil weight of 5w 30 in my jeeps engine. I was never really picky about the brand of oil I used. As long as it did it's job. I was so wrong. I've been having a few miner issues with the performance of my Jeep. When I talked to my mechanic he said it's your oil, try a different brand. So Pennzoil it was and I'm glad I did. My Jeep engine sounds better. It was quick and easy to change my oil myself and I'm loving the Pennzoil brand. Great performance!

[This review was collected as part of a promotion.] I wanted to start using a full synthetic oil for my vehicles. I wanted a name brand that I could trust. I have used Pennzoil for 45 years. I have used it in every vehicle that I have owned. Changing to synthetic oil for me with the amount of travel I do now yearly makes sense. Going longer between oil changes and the heat protection it will provide are the key reason for the change. Convenient six pack is right for me.

[This review was collected as part of a promotion.] Pennzoil full synthetic oil is awesome!! My car responded very well to the Pennzoil full synthetic on this recent oil change. I could tell a big difference in how she sounds and runs since changing the oil. This has to be one of the best synthetic blends on the market. My car has never responded so well in all my oil changes. Improved gas mileage for one is a big plus and a smoother ride all together. Many people don't realize that the quality of oil is important and Pennzoil outshines the rest. I am definitely using Pennzoil full synthetic again on my next oil change.

[This review was collected as part of a promotion.] I have used Pennzoil for years. My dad used Pennzoil in everything when I was little. I got a case of synthetic oil for all of my annual services on all of my small gas engines. I have done all of my preventative maintenance with Pennzoil and never have had a problem.

[This review was collected as part of a promotion.] The Pennzoil Full Synthetic Oil seems to be a great motor oil for my vehicle. The contents of the container is easy to pour into my engine. My vehicle seems to run well. I am impressed with oil because I have never used this oil before.

[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.] I was sent a case of six bottles of Penzoil Full Synthetic oil to try. First off I was shocked that I ended up getting a case of this oil. This oil works great for my car. Sometimes I tend to buy cheaper oil and I think that that oil does not work as well. Using Penzoil I know that it is better for my car and lasts longer. Having six separate bottles is more convenient than having to store a big bottle. This oil has just the right amount of thickness, meaning its not watery like some other brands.

[This review was collected as part of a promotion.] I purchased this pennzoil motor oil due to needing an oil change in my truck. I always use pennzoil full synthetic motor oil. This is great oil and I would definitely recommend this oil for anyone needing oil.

[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 oil is priced well, and seems to work as well as other brands I have used in the past. The oil pours smoothly and quickly unlike thicker weights of oil, and was just the right amount for my 04 acura.
