REFUELING

Use unleaded gasoline with a pump octane rating of 86 or higher. This

produces fewer engine and spark plug deposits and extends exhaust
system life.

be burned or seriously injured when refueling.
• Stop engine and keep heat, sparks, and flame away.
• Refuel only outdoors.
• Wipe up spills immediately.
