Just wanted to compliment you on a fine product called Enviro-Save. I recently purchased a kit from Mr. Bill Kern. Your representative here in Wamego, for my trash hauling truck. We treated the engine, a 671 Detroit, and have noticed more pep and higher top end RPM's.
The most amazing part of the treatment came from our transmission. I had called several repair shops because the noise and vibration from my transmission was telling me I was in for a $1500.00 repair job. We added the recommended bottle of treatment and almost immediately felt a difference. Within 100 miles the noise and vibration in the gearshift were virtually gone. I believe the treatment has saved me $1500.00 already. I am very satisfied and am planning to treat my Dodge 4WD pickup with the 5.9L Cummin diesel engine in it as soon as possible.
