Engine Maintenance

Periodic maintenance must be performed in order
to keep your engine in proper operating condition. After
each day of running, it’s critical to use high quality after-
run oil to protect the internals of the engine and guard
them against corrosion. The methanol used in the fuel
attracts moisture that can cause corrosion (particularly in
the ball bearings). We recommend Blue Thunder™ Final
Run (DYN2255) as it’s specifically formulated to protect
your engine between uses. Follow these steps after
running your engine:

1) Empty all fuel from the tank and fuel lines.

2) Use Final Run fuel following the instructions on

the container.

3) Clean and inspect the engine and fuel system.
