Can I over treat my vehicle with Enviro-Save?
When you treat your engine with Enviro-Save the first time, the Enviro-Save resin is forced into the asperity structure of the metal. When the Enviro-Save product has formed and no more resin can be squeezed into the surface of the metal, the rest of the Enviro-Save resin will hang in suspension until your next oil change when it goes out with the waste oil. Additional treatments will not form a better surface than the first one, so continually re-treating an engine is a waste of your money.
