There are 2 treatment applications –
The 1st, Initial Treatment, is designed for the very first oil flush of an engine. Typically the engine will have heavy sludge build up in many internal component areas throughout the entire engine. The Initial Treatment is a highly concentrated, heavy-duty application where the Flushing Oil Concentrate works hard to break down and suspend all contaminants, especially hard, baked-on carbon deposits.
The 2nd, Routine Maintenance Treatment, is designed to ensure the engine components are kept clean in subsequent, scheduled maintenance oil services, i.e. subsequent oil changes after the Initial Treatment application. This application is less concentrated because there will be much less sludge build up since the 1st Initial Treatment. It ensures all critical internal engine components remain clean, and engine destroying sludge and other contaminants are removed before they can cause serious problems.
