[This review was collected as part of a promotion.] I used this on my car and the difference can be felt immediately. My car is showing better performance now. I love that it enhances wear protection and less oil change is required too. Awesome one for my old car with old engine.

[This review was collected as part of a promotion.] I prefer using a full synthetic oil in my cars. This Pennzoil 5W-30 has worked well and I have had no issues with it. The bigger jugs make it easy to pour in and cuts down on plastic with the smaller bottles. I recommend this full synthetic oil.

[This review was collected as part of a promotion.] I got this Pennzoil full synthetic to use in my f150. I usually take it to the dealer and they use a synthetic blend. Well my warranty is up so I figured I'll start changing my own oil and at the same time this will give me a chance to keep an eye on what's going on under the truck. (leaks and such) I've used pennzoil in the past on other vehicles with good results so this was pretty much a no brainer. Time will tell but with a company that's been around this long they must be doing something right!

[This review was collected as part of a promotion.] Cleaner pistons, better fuel economy, made from natural gas not crude - what's not to love? The 5 quart bottle is convenient to both use and store in my shed for future use. This is the only synthetic oil I will use for my portable generator in Florida to help keep it ready for emergencies.

[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 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.] Pennzoil is a brand that I have always admired. I use it with the confidence because quality is in it's name. There are many brands to chose from but you will never go wrong using Pennzoil Synthetic. It's a name that's been around a long time and you can trust that.
