Oil

Oil Recommendations

• We recommend the use of our Warranty Certified oils for best performance. Other high-quality detergent oils are acceptable if classified for service SF, SG, SH. SJ or higher.
• Do not use special additives.
• Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to select the best viscosity for the outdoor temperature range expected.

Note

• Below 40 F ( 4 C ) the use of SAE 30 will result in hard starting.
• Above 80 F (27 C °) t he use of 10W-30 may cause increased oil consumption. Check oil level more frequently.

Before adding or checking the oil

• Place engine level.
• Clean the oil fill area of any debris.

How to Check/Add Oil

1. Remove the dipstick (O) and swipe with a clean cloth (Figure 1).
2. Insert the dipstick into the filler neck without screwing it in.
3. Remove the dipstick and check the oil level. Make sure the oil is at the FULL mark (B) on the dipstick.
4. To add oil, pour the oil slowly into the engine oil fill (A). Do not overfill. After adding oil, wait one minute and then recheck the oil level.
5. Replace and tighten the dipstick.

Fuel Recommendations

Fuel must meet these requirements

• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.
  CAUTION: Do not use unapproved Gasoline, such as E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. This will damage the engine components and void the engine warranty. To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See Storage. All fuel is not the same. This engine is certified to operate on gasoline. The emissions control system for this engine is EM (Engine Modifications).

High Atitude Operation

Your engine is configured for operation below 2,000 feet altitude at the factory. Your engine must be reconfigured for operation above 2,000 feet altitude. Operating the engine with the wrong engine configuration at a given altitude may increase its emissions, decrease fuel efficiency, degrade per- formance, and cause irreversible damage. Engines configured for high altitude operation cannot be operated in standard altitude conditions. A qualified service center should ensure that your engine is properly configured for your location.

How to Add Fuel

• WARNING
• Gasoline and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death.
• When Adding Fuel
  • Turn engine off and let engine cool at least 2 minutes before removing the fuel cap.
  • Fill fuel tank outdoors or in well-ventilated area.
  • Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of neck to allow for fuel expansion.
  • Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition sources.
  • Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
  • If fuel spill, wait until it evaporates before starting engine.
• Clean the fuel cap area of dirt and debris. Remove the fuel cap.
• Fill the fuel tank with gasoline. To allow for expansion of the gasoline, do not fill above the bottom of the fuel tank neck.
• Reinstall the fuel cap.
