[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.] As usual great product. I’ve been using Pennzoil for years and this is my first time trying the full synthetic I was hesitant at first because I didn’t know much about synthetic oil. After some research at homework I found out the Pennzoil is one of the top oils in full synthetic. I am completely impressed and amazed by the quality that Pennzoil is presented in this product I highly recommend anyone looking for a full synthetic oil.

[This review was collected as part of a promotion.] Great product. Works great in my car. No issues. Lasts long time. Only product I use in my cars. Cara always run great with it. Never had any issues with either vehicle using this product. My wide won't use anything else.

[This review was collected as part of a promotion.] After using this motor oil, I’m extremely impressed! The first thing I love about this oil is how well it maintains my engine’s performance. Ever since I put this oil into my vehicle, I’ve noticed improved gas mileage and have experienced nothing but smooth rides. My engine has also been able to maintain a consistent level of power during “intense activity” (such as driving up hills or mountains). Additionally, I really appreciate how smoothly the oil flows out of the container. It’s easy to fill my vehicle with the oil using this container’s convenient design. The size of the bottle is also perfect for occasionally topping off my oil levels. Overall, I’m extremely impressed with this oil and would recommend it to anyone in search of a high-performance oil that is sure to help your car live a long 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.] I love this brand of oil, especially the full synthetic type. Use this in my 14 Edge and go for 10,000 miles. I've used many different brands over the years, but always go back to Penzoil for it's quality and availability.

[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 recently tried Pennzoil full synthetic 5w20. After I changed my oil and filter I noticed more power during acceleration and less delay in my engine. I highly recommend Pennzoil products to bring your vehicle to life.

[This review was collected as part of a promotion.] Got this about a week ago to change the oil in my mom's car. Figured I had a little time, so why not do it myself? Use to do it all the time. Well, cars have changed since then, and it wasn't such an easy job anymore. Had to get some help...called in a mechanic friend to finish the job, and he and I both noticed the Pennzoil Full Synthetic has received excellent marks for durability and protection. It might be wishful thinking, but mom's car seems to be running better, just with the Pennzoil oil change added. Think I'll be changing all my cars to this product soon!!!

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!
