Why do diesel buses and truck engines require additional product?
The Enviro-Save resin is driven deeper into the asperity structure of the metal by the higher compression found in diesel engines. Since the benefits of the Enviro-Save resin comes from Enviro-Save-to-Enviro-Save contact inside of the engine, more product is required to adequately form the surface. It is the Enviro-Save resin on the surface of the metal that protects the engine from wear. Turbo-charged and Super turbo-charged diesel engines have even higher than normal compression and require more Enviro-Save liquid than an average diesel engine. Buses require more fuel additive because of the complexity of service from the time they leave the garage until they return many hours later.
