[This review was collected as part of a promotion.] I've been using Pennzoil oil for a very long time. And now that our Honda is getting a bit up there in age and wear, I decided I wanted to transition to synthetic oil. Since I e made the transition, I've noticed a slight increase in fuel efficiency and how the engine runs. I'm excited to see how well it performs as the year goes on, but I know I can always trust Pennzoil, so I'm expecting solid results!

[This review was collected as part of a promotion.] This is a great oil. I have used it on foreign and domestic cars with over 100,000 miles. Always last long and a good choice overall. I will definitely continue using pennzoil products in the future..

[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.] 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.] Pennzoil full synthetic oil works great for my truck. I just did an oil change with it and my motor seems to run smoothly. It is greatly priced and it can be used in my boat, vehicle and my lawnmower which is amazing. It is a trusted repeatable company that I trust. It is alway good to keep an extra in the car. I used a different brand previously but I will be sticking to Pennzoil strictly!

[This review was collected as part of a promotion.] I love my Pennzoil Full Synthetic oil! I use it in all of my vehicles. I used the Pennzoil Full Synthetic 5w 20 in my 2010 Honda Accord and it continues to run like a champ! I change my oil as soon as the "Oil Life" reaches zero and I have not had any engine problems. I am a firm believer that if you change your oil on a regular bases with quality oil, your engine will last you a long time. I have been using Pennzoil in my 2003 SUV and it has 257,000 miles on it and still runs great! I highly recommend Pennzoil!

[This review was collected as part of a promotion.] I had an oil change using the Pennzoil full synthetic oil and my car seems to run very well. The 5w -20 oil is working to keep my engine clean and protect against friction. I had my mechanic use it and my car runs great.

[This review was collected as part of a promotion.] My car only takes full synthetic oil so this pennzoil is a great oil for my car. The bottles were easy to open and easy to pour. I am sure I will get the full mileage out of the oil. The bottles can be recycled which is a big plus.

[This review was collected as part of a promotion.] I have been using the Pennzoil full synthetic for my car and it is the absolute best It gives my car full protection for those critical engines’ parts. With Pennzoil full synthetic, you will need fewer oil changes that a conventional motor oil. It comes with enhanced wear protection for high and low temperate. I have noticed my engines runs more smoothly and the car feels like and drive new. The Pennzoil helps present sludge and deposit build up. I use this oil up to 10k miles and then do another change. I trust a name like Pennzoil for my engine and I never do an oil change without it.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic 5w30 case of 6 is very convenient and a bit cheaper to buy than buying 6 individual. We have several vehicles so need to buy a lot of oil. Best oil we've bought in a while its quality is superb
