Preparing Machinery for Winter

We spent a few hours getting the petrol engined tools which we use in the orchard, ready for winter. I was quite surprised when I realised we now have six such tools. Most of the work was following the maintenance schedule such as oil changes and cleaning air filters. However one item was dealing with fuel (petrol) for the motors. I hadn't realised fuel from the forecourt can go off in as little as 30 days. Using stale fuel can damage a motor, particularly the small high revving 2-strokes.
The usual advice is to drain the fuel systems over Winter and to fill with fresh fuel in the Spring when you start to use the tools again. After some investigation we decided to empty the tanks and refuel them with fresh petrol treated with "Fuel Fit" petrol additive from Briggs and Stratton. This keeps fuel fresh for up to three years. An alternative would be to swap over to Aspen alkylated fuels, they contain fewer impurities and last for a couple of years. Aspen is about three times more expensive than forecourt petrol. Fuel Fit costs about £8 to treat 25 litres of fuel.

None of this equipment is stored on site.
