Does STM-3 replace existing oil or grease volume?
No! Unlike additives, STM-3 does not change the lubricant base, because STM-3 is a metal treatment. Most anti-friction additives change the oil, thereby altering the delicate formulation of the oil or lubricant. When a petroleum based oil additives replace or alter the oil with which the engine is designed to operate, the additive package pH and suspension agent of the oil may be altered. When the pH is wrong, the “additive package” is out of balance and can cause acidic buildup and corrosiveness. STM-3 does not change the properties of your lubricants .
