Tom W. From Boston, MA. Declares Lucas Oil Products have never let him down!

I usually don't contact manufacturers to tell them how great their products are but this is an exception. I have been driving a 1997 Dodge Caravan that just won't quit. Recently it began stalling out at idle, at stop lights and while cornering. I really don't want to put a lot of money into this car and decided to try an additive. Against my better judgement I tried a competing brand that was on sale and it did absolutely nothing. I then bought a 5.25 bottle of Lucas Upper Cylinder and Injector Cleaner. I emptied it into a 1/4 full tank and drove about 5 miles to a gas station. I filled the tank, left for home (about ten miles) and by the time I got home the problem was solved. Four weeks later it's still running strong and has not stalled once. I should have bought Lucas in the first place and will continue to do so. Lucas products have never let me down.

Thanks for all of your great products.
