The ultimate fully synthetic 2-stroke off road racing engine oil! Formulated using Electrosyntec Technology to provide exceptional anti-seize properties, usually only associated with castor-based oils. Grand Prix track experience has proven that PRO 2 SX provides the latest racing engines with outstanding load-carrying and cleanliness necessary for full power output, even at high fuel to oil ratios. Combats varnish and carbon deposits and is resistant to ring-sticking and plug fouling, helping to maintain full output for the track life of an engine. Contains special additives to prevent the throttle sticking in wet conditions, a problem experienced with some types of racing carburettors. Forms a highly effective seal between cylinder, piston and ring, enabling the engine to produce optimum power throughout the rev range. Extends engine life and can double crank life in certain applications.
