fresh, use fuel stabilizer.
If fuel stabilizer is added to fuel system,
prepare and run engine according to
Washer Start-Up. Run engine for 2 minutes to
circulate stabilizer throughout fuel system.
Adequately prepared fuel can be stored up to
24 months.
NOTE: If fuel has not been treated with fuel
stabilizer, it must be drained into an approved
container. Run engine until it stops from lack
of fuel. Use of fuel stabilizer in fuel storage
container is recommended to keep fuel fresh.
