By the way I also want to let you know that since using the Lucas Fuel additive in my 2001 Volvo that the car is running great and the fuel mileage has increased, the car presently has 191,000 miles on it and runs like a new car, so thank you for the additives. I also have been using the product in my wife's Mitsubishi Eclipse GT and again the mileage is better and the car runs smoother. I have recommended it to numerous other people and have gotten the same response on mileage and smooth running.
