Drydene DRF­® A-Main Synthetic SAE 10W-40 Racing Oil

Part #D15301

DRF A-MAIN SYNTHETIC 10W-40 RACING OIL is built from the most chemically advanced synthetic base oils and proprietary additives that promote increased horsepower and torque while lowering oil and water temperatures when compared to competing brands. DRF A-MAIN SYNTHETIC OILS are highly shear stable and help unleash maximum power from competition racing engines where high lap counts or extreme temperatures may be a factor.

3/1 Gal Case, 6/1 Qt Case

Product Applications

DRF A-MAIN  SYNTHETIC 10W-40 RACING OIL is designed for small block and big block circle track racing engines that compete on dirt and asphalt. DRF is formulated for and compatible with gasoline, racing gasoline (leaded and unleaded) and methanol.

Features & Benefits

DRF A-MAIN SYNTHETIC 10W-40 RACING OIL reduces surface friction which helps lower engine temperatures and allows for maximum combustion and torque during acceleration and at full speed. The unique surface-active chemistry built on Competition-Grade ZDDP™ delivers bonds to and protects pistons, crankshafts, bearings and cams.

• Is blended with pure synthetic base oils to provide robust film strength and consistent viscosity to heavily loaded engine components
• Improves torque and horsepower while also lowering oil and water temperatures even at peak RPM over prolonged periods
• Provides exceptional shear stability and maintains correct viscosity lap after lap, even in extreme conditions
• Promotes rapid air bubble dissipation and minimizes foaming
• Helps reduce the effects of race fuel dilution and reduces oil consumption even in severe conditions
