[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.] Pennzoil Full Synthetic is their top of the line oil. I have used it for years and it keeps the engine clean and running great. Meets Chrysler and Ford specs along with many others. 5000 miles between oil changes is no issue!

[This review was collected as part of a promotion.] I have always used Pennzoil in all of my vehicles. This is another great great product that they make! It makes my motor run smooth while offering great protection for it. If you haven't tried Pennzoil, you definitely don't know what your missing out on!

[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.] Its exactly as expected. Its a brand I trust and use quite often. It comes in convenient bottles that is easily poured. Just the amount needed to change my oil. Its great. It keeps my car running properly. I would definitely recommend this brand.

[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 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.] The Pennzoil Full Synthetic Oil is high quality and long lasting. It has the highest protection for my internal engine parts and will be a constant in the my oil changes moving forward. It has made my engine and car run smoothly which is fantastic.

[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.] I did an at home oil change on my wife's RAV - 4 over the weekend. I tried the Pennzoil Full Synthetic 5W - 20 over my other synthetic choice. I honestly prefer Pennzoil, the weight, color and lack of oil smell was nice so my wife didn't complain. She just drives the car so hasn't noticed any change in the ride or power.
