[This review was collected as part of a promotion.] I have been using Pennzoil for as long as I have been driving. I have never had any issues that were oil based. It works great, and has a great legacy behind it. I'll continue using Pennzoil in all my cars going forward.

[This review was collected as part of a promotion.] Lasted 5k miles without burning just as it should. I put in about 3k miles a month, and it lasted me the whole months and a half before i got the time to do the next oil change. Definitely gets the job done

[This review was collected as part of a promotion.] This is a great product from Pennzoil. The quality of the oil after 5,000 miles is great. It wasnt watery so the viscosity holds up great. Great synthetic oil you can trust. I'll keep using Pennzoil for all my vehicles.

[This review was collected as part of a promotion.] I picked this up to save a trip to the mechanic. I love the way this oil last longer than regular oil and it’s not that much more expensive. I highly recommend it to anyone wanting to change their own oil

[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.] I have used different brands of oil in my vehicles over the years but the brand I keep coming back to is Pennzoil. Their full synthetic oil keeps my engine running smooth and I seem to get better fuel economy with it. I'll keep using the brand I trust.

[This review was collected as part of a promotion.] I decided to spend the money on full synthetic oil and save money on the labor by doing the oil change myself. I had been taking it to the shop. Now that my son is old enough ,and wants to work on cars, I thought this would be a great start. I can only assume there are no problems since there are no problems. Right? Many miles to go, and then we will do it again.

[This review was collected as part of a promotion.] Since 1913 Pennzoil has been a true and trusted product for autos. And they've continued caring for our cars and trucks by coming up with a full synthetic oil that not only better protects our engines, it also outlasts regular oil allowing more miles between oil changes. It's a great product for my car which has over 200,000 miles, and is still going strong.

[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.] 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.
