My husband and I just returned from a trip from Florida to Indiana and back. Our 2001 Buick Century has over 203,000 miles on the odometer. Just before the trip I changed the oil and replaced on quart with Lucas Heavy Duty Oil Stabilizer. With each tank of fuel I added Lucas Fuel Treatment. My gas consumption ran between 30-33 mpg. Needless to say, I am convinced your products work and will continue using them in all my vehicles.
