No. Cerma STM-3 Engine Treatments do not affect warranties because they do not affect the pH, nor do they blend with any lubrication fluid into which it is introduced. Cerma STM-3 Engine Treatments do NOT treat the oil or the fluid into which it is introduced. Cerma STM-3 Engine Treatments treat the metal only by using the lubricant as a carrier. In addition, Cerma STM-3 Engine Treatments do not affect, in a positive or negative way, any type of seal material.
