Jeff D. from Illinois has an older car, an '89 Volvo station wagon. He purchased both Ethanol Defense and Engine Flush and wrote us, very happy with his results: "Improved my gas mileage by 9% AND my engine runs quieter, much smoother and acceleration improved noticeably. I have a '89 Volvo 740 station wagon with a 4 cyl. engine and 235,000 miles on it. When I have the car restored including re-built engine and new fuel system, I am confident I will get another 10% improvement in gas mileage."
