T-4MXR is a blend of specially selected synthetic and petroleum base oils for off road four stroke racing engines. Provides the highest degree of protection under extreme temperatures, severe shock loads, and peak RPMs. T-4MXR improves ring seal, protects valve train, eliminates deposits, controls foam, resists high shock loads, and provides smooth, positive clutch activation.

GP-7 is a 100% synthetic oil specifically designed for high output two-stroke racing engines. GP-7 utilizes Torco's advanced smokeless technology to increase power efficiency, improve throttle response, and provide "ultra-clean" performance. A combination of synthetic fortifiers and additive systems provide protection under extreme temperatures, high rpm, and load conditions. GP-7 is blended for maximum performance and will prevent fouling, pre-ignition, ring sticking, and power valve deposists. Premix only.
