David McOwen uses Lucas Transmission Fix in 1998 Dodge

It took 5 months for my wife Debi and I to leave New Orleans after Hurricane Katrina but we finally sold the house and bought a house in Oklahoma. In January when I was pulling a 3,000 lb trailer with my 1998 Dodge Caravan I couldn't get past 55 miles per hour and I was burning gas up like crazy, motor running hot and noisy. At one station I noticed the Lucas Oil and Transmission treatment. First I put the Oil in and the Engine quieted right up (no more clicking valves) and the temp came down. Then I put the Transmission treatment in and got back on the road. It passed 55 easily and was able to cruise along at 70 without straining, stayed cool, quiet and decent gas mileage. Just this month I had a gas sensor problem where it would keep dropping to empty, low fuel light would come on and it would ding like crazy. I put the Lucas Fuel treatment in and the sensor straightened right out and hasn't given me a problem since. Like I said I am a walking Lucas commericial. Great stuff.
