[This review was collected as part of a promotion.] Have been running this in my 2014 Wrangler (145k+ miles) since we reached 75k+ and couldn't be happier. Long lifespan and has been great in preventing other engine issues and usually get at least 4,000 miles per oil change

[This review was collected as part of a promotion.] Pennzoil full synthetic oil is top quality. took the oil to my mechanic to do an oil change for me. He said that I got the "right stuff" and that Pennzoil is what he recommends. My car is running great and I am very happy with everything.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is entry level synthetic oil for people changing from regular oil or blend to full synthetic oil. Pennzoil is great and I always depend on it to keep my vehicle running smoothly

[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've only recently made the switch to using Full Synthetic oil on my SUV and chose Pennzoil. I change my engine oil every 5,000 miles and extremely happy with the performance of my engine after the first oil change to Pennzoil synthetic. The SUV runs smoother and quieter than before. Engine runs smoothly after

[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 was sent a case of six bottles of Penzoil Full Synthetic oil to try. First off I was shocked that I ended up getting a case of this oil. This oil works great for my car. Sometimes I tend to buy cheaper oil and I think that that oil does not work as well. Using Penzoil I know that it is better for my car and lasts longer. Having six separate bottles is more convenient than having to store a big bottle. This oil has just the right amount of thickness, meaning its not watery like some other brands.

[This review was collected as part of a promotion.] Pennzoil is by far the best engine oil I’ve used so far. I feel much better putting this oil in my car. I’ve gotten great performance from my car. The engine sounds great and runs smoothly. This is a great oil for my car.

[This review was collected as part of a promotion.] I have been using Pennzoil motor oil for many years and have come to trust the brand. I recently added this full synthetic oil to my vehicle and am very confident with the quality. The bottle was easy to pour with no mess.

[This review was collected as part of a promotion.] I often find myself helping family out with oil changes at my place. I always like to have some on hand and went for this. Absolutely great quality for the price. I now keep this available in my garage all the Time. I do recommend
