Diesel formula STA-BIL Fuel stabiliser keeps diesel fresh whether you're storing diesel in a tank or drum, parking farm equipment until the next harvest or putting the boat to bed for the winter.
As you head back into the winter off-season protect your boat and small petrol fuelled equipment by topping up the fuel tank and adding STA-BIL Storage to the fuel tank.
Degraded petrol is significantly less combustible than fresh fuel and is often the cause of engines that are hard starting and have poor performance. Leave it sitting for long enough and it's likely the engine won't start at all.
