Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline will
cause hard starting, and it leaves gum deposits that clog the fuel
system. If
the gasoline in your engine deteriorates during storage, you
may need to. have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems
will vary with such
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air
in a partially filled fuel
tank promotes fuel deterioration. Very warm storage/temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
within
a few months, or even less if the gasoline was not fresh when
you filled the fuel tank.
The
Distributor’s Limited Warranty does not cover fuel system
damage or engine performance problems resulting from neglected
storage preparation.
You can extend fuel storage life by adding
a fuel stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
