Husqvarna normally recommends 2 % two-stroke oil (1:50) for its chainsaws. This equals 20 ml of oil per litre of petrol, or 100 ml for 5 litres. Use the calculator to work out the oil quantity and always follow the mixing ratio in your machine’s operator’s manual.

Enter an amount greater than zero, for example 5 or 2.5 litres.

Select 2.5 % or 3 % only if specified for your machine. The quantity refers to petrol before adding oil. Ratios above are shown as oil:petrol. The calculator is for petrol to be mixed with two-stroke oil, not premixed fuel.
