revvant Blue Flame GEO 8™ is designed specifically for use in gas fueled medium and high speed (rpm) engines within the transportation industry. Blue Flame GEO 8™ extends engine life through use of its HardBase TBN of eight (8) coming from an exclusive detergent/dispersant additive system that provides a new level of deposit control for low ash oils while also effectively neutralizing the corrosive by-products of combustion.

revvant Blue Flame GEO 8™ is formulated with thermally stable, high VI base oils that are naturally resistant to oxidation. These base oils are combined with a unique additive system that further extends oil oxidation life. Special valve cushioning additive components help reduce exhaust valve seat and face wear during severe service. The medium ash, low phosphorus composition is compatible with exhaust gas catalytic converters and promotes longer spark plug life for minimized maintenance costs.


SAE 15W-40

Viscosity profiles meet the full requirements for protection and performance. Always consult your owner’s manual for proper oil viscosity and quality selection guidance.
