Formulated to deliver maximum starting power for both diesel and gasoline engines. Pyroil Starting Fluid contains the optimum ratio of ether to petroleum-based distillates, found through extensive testing in sub-zero temperatures, to provide a quick, smooth start in any weather. Also effective on lawn mowers, trimmers, chain saws, motorcycles and more. Size: 11 Oz For gasoline and diesel engines Starts engine faster Starts engines quickly, reducing battery drain Starts diesel or gasoline engines Contains an upper cylinder lubricant Fits diesel injector systems Effective year-round, in all weather conditions. How To Use Use outdoors with adequate ventilation. Spray into air intake for 2-3 seconds (no more than 3 seconds). Then start the engine. FAQ's How does starting fluid work? The ether in starting fluid ignites at lower temperatures than gasoline, which allows for quicker combustion and easier starts, while also reducing wear on starters. Additional Info Pyroil Starting Fluid has been formulated to deliver maximum starting strength. Ether and petroleum distillates are blended together to produce a starting fluid which has a low freezing point, high vapor pressure (produces vapor at low temperatures which passes through air intake systems and air filters), low flash point (ignition), high BTU content (starting power) and an upper cylinder lubricant for protection. Extensive testing using a diesel engine in sub-zero temperatures has shown an optimum ether content range exists. Starting fluids containing too much or too little ether failed to start a diesel engine at cold temperatures. Pyroil Starting Fluid gives maximum starting strength by carefully controlling ether content.
