Review of Gunk M7112 Diesel Sulfur Substitute - 12 fl. oz.

Customer Ratings:

Great price on the product. I use it every time I fill up my truck. I wish it was packed better one of the containers that I ordered must have been hit hard in shipping because it was leaking a small amount when I opened the box. Other than that happy about the deal I got on the gunk sulfur substitute. Will be buying more in the future.

This stuff really work for my 99 5.9 cummins. I had always bought it from auto part stores for about $7.00 bucks for 16 oz. This was a real bargin for me
