[This review was collected as part of a promotion.] One of the best oils I have used in my vehicle. I’ve had no issues at all while using this oil. My vehicle runs great. I haven’t had any engine issues. My vehicle runs smoother and it doesn’t skip or anything. This is just one of those brands you can trust. I definitely will recommend this oil and always use it I’m very satisfied.

[This review was collected as part of a promotion.] This is my first time using full synthetic oil and I wouldn’t do it with any other company than Pennzoil. My buddy has been trying to get me to do this for several years but I have been stubborn. I finally decided to give it a shot and put the Pennzoil Full Synthetic in my truck. I have seen a difference already in the way my engine runs. I took it on a 4 hour drive and it was smooth as it was the day I bought it. I am looking to get an extended period on the full synthetic. I will continue to monitor this over the mileage. This oil was packaged in nice quart size individual packaging. Easy to pour and easy to grip. I am currently satisfied and would recommend this oil to anyone looking for a full synthetic oil.,

[This review was collected as part of a promotion.] I received this product for a honest review. This is really good oil. I used it in my car and I noticed how much better it runs for me. I change my oil regularly and will continue to use this oil. Easy to use and pour. Works great!

[This review was collected as part of a promotion.] I usually take my F-150 in to have the oil changed but decided to do it myself. This is some quality motor oil. With the Pennzoil name you know it will be good. I have never tried full synthetic in my truck but with it's higher mileage I think this will work well. I have used Pennzoil products for years in my boats so I have no reason to believe this will be anything but excellent.

[This review was collected as part of a promotion.] Have used Pennzoil products over the years. No issues with them and they have worked in all my vehicles. There has not been any instance where they have caused any mechanical issues and vehicles have run well when they are used.

[This review was collected as part of a promotion.] I use this oil in my lawnmower and it works great. I have not had any issues with using this oil in my equipment. I use the same brand but different weight in my vehicle. I like the synthetic oil due to its longer lubricating capabilities.

[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.] I have switched from regular oil to synthetic one last year and I will never come back. It saves so much time, money and labor work. I use the Pennzoil oil for both my truck and my wife SUV. I do all the oil change so it's great to experience the big difference this oil can make. The cars run smoothly and nicely. But the most important is it takes less time to change oil for each car. Before I used to change at least every 3 months, now I can wait till 9 months or a year depending how much I drive. Like I said earlier, after using synthetic oil, i will never go back to the the regular one anymore.

[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 exclusively use Pennzoil for my car, and it hasn't let me down yet. The engine performs the same or better in this than with the oil recommended by the manufacturer; the Pennzoil almost makes the engine "purr" softly when idle. From what I've read in studies of different oil manufacturers by independent third parties, Pennzoil is in the top 3-4 overall oils when it comes to engine wear, how clean it keeps the engine, and resistance to breakdown. In other words, it appears to be exceptional value for the quality of the oil.
