[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.

[This review was collected as part of a promotion.] I have for a very long time wanted to try a full synthetic motor oil in my vehicle, after using this product I will never go back to regular oil again. I notice o get better gas milage and the car runs much smoother.

[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.] I use this for a multitude of things that uses this oil. It works perfectly in my car. I don't think I have ever had my car run so well before. It seems like it runs smoothly as well. I went on a few trips already out of state and there hasn't been an issue.

[This review was collected as part of a promotion.] Pennzoil is the best oil out there. It has yet to let me down and everytime I've tried a different oil, whatever machine I'm using the other oil on doesn't seem to last as long. Pennzoil guy for life!

[This review was collected as part of a promotion.] If you are like me and do work on vehicles at home like changing oil, adding windshield washer fluids, etc than boy do I have the perfect oil to be used to change yours at home in the comfort of your garage, shop, or even in your driveway or grass. I'm always tinkering with mine and my family's vehicles and one thing I always remember to do is to change the oil as it approaches the mileage recommended. While I've used different brands in the past Pennzoil Full Synthetic is top notch in my book! I get the box containing 6, 1 QT bottles of Pennzoil Full Synthetic 5W-20 which gives your vehicle 40% better performance than conventional motor oil. Although this brand has many varieties this particular one offers not only better fuel economy but it will go longer between oil changes, protection in extreme temperatures, conditions older seals as well as protection against sludge & deposit build up. Those being my main concern with my wife and teenagers driving. It's an amazing feeling knowing this trusted company had any consumers worries to a minimum of not gone completely! I am a repeat Pennzoil purchaser but think I'll continue using this particular one for adding oil to doing the works with helping my family with complete oil changes.

[This review was collected as part of a promotion.] Just did my first oil change with the Pennzoil full synthetic. It was straight forward and easy to use. Excited to see how it performs down the road but it’s working as expected so far! No issues with over heating or oil pressure.

[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.] So glad I came across this! Since using my vehicle seems to even be running better. I’m happy to know there is a product like this that will help keep My vehicle on the road longer! Happy to use and I recommend this type of oil to anyone who can use it!
