TR-4 Oils
 TR-4 is specifically formulated for racing engines using alternative fuels, superchargers, turbo chargers or nitrous oxide systems. The unique blend of synthetic and hydro processed petroleum base stocks provide exceptional thermalstability and optimal ring sealing capabilities under the most severe conditions. TR-4 incorporates a unique combination of race specific additives and polymers designed to reduce wear, eliminate deposits and maintain optimum oil pressure. TR-4 also utilizes Torco’s MPZ chemistry which reduces frictional losses for increased horsepower and torque.
