[This review was collected as part of a promotion.] I used the Pennzoil Full Synthetic 5W-30 in my Chevrolet 6.0 after verifying it is Dexos approved. My mechanic commented that it is excellent oil. It functions well, holds good oil pressure and the engine ran cool and quiet.

[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 am a huge supporter of the fully synthetic oil. Runs great in my jeep and I have never had an issue with it. I do all my oil changes myself and have been a pennzoil man through and through. Superior product at a superior price!!

[This review was collected as part of a promotion.] This oil works great! Car runs well. Pennzoil has always been a good quality company and one I can count on for knowing I’ll have a good quality oil in my car. It works great and car runs well. Easy to change.

[This review was collected as part of a promotion.] My vehicle takes synthetic oil but it's a big cost to get it changed so I invested into doing it myself. Normally I would get my oil change done at places, with a high cost, and a lower level oil but today...today! I will commit to changing it myself. No more stripped out bolts, no more leaks, today I get to batten down all my hatches and create an oil change I know won't go wrong.

[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

[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 have always used Pennzoil products in all of my engines. When I recently purchased a newer car, I had the chance to run the full synthetic. Now I have changed over to the full synthetic in every application possible. This stuff is the good stuff! Great bottles with easy to open/pour packaging.

[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.] This is my favorite oil. It out preforms all the other oil brands in my book. If you don’t get your oil changed every 3,000 miles this oil will help keep your car moving. It’s just the best in my book.
