Gas Engine Oil Additive Package
CAS Number: N/A (formulated 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.

| kinematic viscosity (100°C) | ~135 mm²/s (RF6208) |
Applications
- Stationary natural gas power generation engines (Caterpillar G3500/G3600, Jenbacher Type 4/6, Waukesha)
- CNG / LNG fueled commercial vehicles (transit buses, refuse trucks, long-haul tractors)
- LPG and propane-fueled industrial engines
- Biogas / landfill gas / sewage gas combined heat and power (CHP) plants
- Dual-fuel engines (diesel-gas) requiring controlled ash for both fuels
Key Features
- Controlled ash content prevents spark plug fouling and pre-ignition while protecting valve seats
- Strong antioxidant package for the high-NOx, dry combustion environment of gas engines
- Nitration and oxidation resistance for extended drain intervals (>1000 h stationary)
- Compatible with all major OEM gas engine approval specs (Caterpillar, Jenbacher, Waukesha, Cummins ISX-G)
