Why is it important to empty fuel tanks in power equipment during off-season storage?

Emptying fuel tanks in power equipment during off-season storage is essential because it helps prevent fuel from degrading and clogging the fuel system. Over time, gasoline can break down and form varnish and sediment, which can lead to complications in the engine. This degradation can occur from exposure to air and moisture, particularly in a tank that is partially full, where the fuel is more susceptible to oxidation and evaporation.

When the fuel degrades, it can clog fuel lines, filters, and carburetors, causing starting issues or poor performance when the equipment is used again. By emptying the tank, the risk of these problems is significantly minimized, ensuring that the equipment is in good working condition when it is taken out of storage.

While avoiding spillage, reducing weight, and improving fuel floatation might seem relevant, they do not address the critical issue of fuel integrity, which directly impacts the operation of the equipment.
