[This review was collected as part of a promotion.] I have never tried the synthetic oil previous to this. I heard rumors to stay away from synthetics in the past. My son in law is a farmer,( they use a lot ) and he is the one that convinced me to try it. I have it in my riding mower and truck. I guess I had some bad information.

[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.] The Pennzoil Full Synthetic is my oil of choice when it comes to all my lawn and garden equipment. I truly trust this oil and know that it will perform at its best and keep my equipment running at peek performance. The full synthetic is what I prefer to use and I know the Pennzoil brand is a name I can trust for ongoing performance. Highly recommend

[This review was collected as part of a promotion.] I really think that Pennzoil Full Synthetic motor oil is the most reliable, best quality motor oil a car owner can buy for their automobile, I have been a loyal user for years and have only seen great results. I would not use any other brand. I would definitely recommend Pennzoil Full Synthetic to anyone wanting a wonderful product for their vehicle.

[This review was collected as part of a promotion.] I got the Pennzoil Full Synthetic 5w-20. If you change your own oil this is the oil for you. Pennzoil Full Synthetic motor oil is made from natural gas which makes it much more pure than oil made from crude. It is proven to provide better protection and lasts longer than oil made from crude. Compared to other oil Pennzoil works great on my 2008 Dodge Ram pickup with high mileage .I would definitely recommend.

[This review was collected as part of a promotion.] I have been a valvoline user for years but then I happened to try this Pennzoil Full Synthetic and I am I happy I did. I can just feel my Jeep running smoother. It starts with ease and runs like a champ and I will be sticking with Pennzoil Full Synthetic.

[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.] Great product. Works great in my car. No issues. Lasts long time. Only product I use in my cars. Cara always run great with it. Never had any issues with either vehicle using this product. My wide won't use anything else.

[This review was collected as part of a promotion.] I got this to try in a vehicle we have with high milage. We have only used synthetic oil in our vehicles for about the last 25 years. This Penzoil product seems to perform well compared to my regular brand. Even though it's the summer and it has not been in the vehicle very long it does seem to be doing an adequate job. I would like to reevaluate in the winter and at the end of this oil's life cycle, but not sure I know how to reaccess the review site.

[This review was collected as part of a promotion.] I bought this to try the Pennzoil brand on the full Synthetic oil and seems to be good quality, used it on my 2015 jeep renegade, will see after 1000 miles how is the color and texture, the kit is convenient and had enough oil for the change
