[This review was collected as part of a promotion.] I had an oil change using the Pennzoil full synthetic oil and my car seems to run very well. The 5w -20 oil is working to keep my engine clean and protect against friction. I had my mechanic use it and my car runs great.

[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 love this brand of oil, especially the full synthetic type. Use this in my 14 Edge and go for 10,000 miles. I've used many different brands over the years, but always go back to Penzoil for it's quality and availability.

[This review was collected as part of a promotion.] Pennzoil Full Synthetic oil is the way to go when you want high quality and a reliable product to keep your vehicle in great shape. It is the best oil out there. It is easy to use. The container itself is made where I have no problems with the oil leaking out of the bottle or anything.

[This review was collected as part of a promotion.] I recently purchased some Pennzoil Full Synthetic Motor Oil. This oil is very reliable to use since it is manufactured by Pennzoil. This company has been around for many years, I know because I used it when I was a kid and that's been a long time ago. The use of this oil allows you to go many more miles between oil changes. The full synthetic oil is manufactured from natural gas which is very good for emissions and is readily available. It meets all gasoline engine manufacture's requirements. I thoroughly recommend this motor oil.

[This review was collected as part of a promotion.] I used this to change the oil at home in my car and had no problems using it. The jug has two areas you can use as handles which is nice so you can tilt it all the way to get it all poured out. It has my car running great just like it should.

[This review was collected as part of a promotion.] This Pennzoil Full Synthetic oil was super easy to use it made for great performance in my vehicle. It was easy to distribute with the shape of the bottle. I absolutely stand behind this brand. I would not turn to anything else.
