drained, start engine and let it idle until all fuel is
consumed and engine stops. Repeat the starting
procedure two more times to ensure all gas is
removed from the engine. If gasoline is not drained,
gum-like varnish deposits will form and cause poor
engine operation, even starting problems.
Fuel can be left in gas tank only if a fuel additive,
such as Toro's Stabilizer/Conditioner, is added to
gasoline before storing. Toro's Stabilizer/Conditioner
is a petroleum distillate based conditioner/stabilizer.

base, such as ethanol, methanol or isopropyl. Use fuel
additive in recommended quantities as specified on
container.
