Danny Long now has 264K Miles on His Truck and Uses Lucas Oil Stabilizer With Remarkable Results

I have used your gasoline treatment and your engine oil stabilizer with remarkable results. I now have 264000 miles on my truck and it still doesn't use a drop of oil between oil changes. I try to change my oil around 3000 mile but realisticly I don't get it changed until It has around 5000 miles on each change. I also use the gasoline  treatment and I'm totally impressed with it. My thoughts before I actually used this product were \ I bet this stuff is a joke I can't see how one little bottle of this stuff could do anything,\ Well I was way off base this product really works my truck engine runs so much smoother with this product in the tank and it also boost my miles per gallon.

Mr. Lucas these are two great products!
