GP-7 is a 100% synthetic oil specifically designed for high output 2-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 plug fouling, pre-ignition, ring sticking, and power valve deposits. Premix only.
