This is a genuine 1-litre fuel mixing bottle designed for accurately mixing petrol and 2-stroke engine oil. Its translucent, fuel-resistant construction features clear measurement markings on both the bottle and cap, making it easy to prepare the correct fuel ratio for STIHL and other 2-stroke outdoor power equipment. The narrow spout of the STIHL mixing bottle helps professionals and domestic users to decant the fuel mixture precisely into the tank.
