Gas Engine Oil Additive Package
Gas engine oil additive package formulated for stationary and mobile natural gas, CNG, LNG and LPG engines. Provides controlled sulfated ash content (low/medium-ash variants) to balance valve seat protection against ash-induced spark plug fouling. Delivers oxidation resistance for the high-NOx, dry combustion environment characteristic of gas engines. Richful RF6208 (medium-ash mobile long-mileage variant) is a typical grade for CNG truck and bus engines.
