Five x 250ml Bottles Briggs & Stratton Fuel Fit Stabiliser 992381 Use Briggs & Stratton Fuel Fit™ fuel stabilizer products to help keep your fuel fit for up to 3 years, promote quick starting, & clean the fuel system. Briggs & Stratton’s new & enhanced Fuel Fit® keeps fuel fresh & protects engines more than ever before. Fuel Fit not only keeps the carburettor clean for easy starting but now also protects against the corrosive effects of ethanol & maintains fuel stability for up to 3 years. Currently in the UK; unleaded fuel can contain up to 15% ethanol. Ethanol is Hydroscopic (meaning that it attracts & readily bonds with atmospheric moisture). If ethanol & water are mixed together it becomes corrosive to rubber & metal components. Petrol also begins to degrade, forming varnishes & gums, clogging fuel lines, sticking valves & blocking carburettors, resulting in difficult starting, overheating & poor performance. Fuel Fit’s newly developed advanced ‘triple antioxidant’ formulation with additional ingredients protects your engines through its latest technology: Corrosion inhibitor that forms a protective barrier on metal parts against harmful effects of ethanol-water mix Detergent ingredients to prevent gum & varnish build-up on engine parts Metal de-activators which stop chemical reactions caused by dissolved metals in fuel 250ml Fuel Fit treats up to 25 Litres of Unleaded Fuel
