Reducing Mower Emissions

Emissions from Briggs & Stratton engines manufactured today average 75% less than 1995 models. In addition, up to half of emissions from outdoor power equipment is preventable.


Here are some ways homeowners can join Briggs & Stratton's efforts to reduce outdoor power equipment emissions even further:

Fuel Tips

  • Mower MaintenanceUse fresh, clean, lead-free gasoline.
  • Fill the fuel tank only three-quarters full, allowing room for expansion without overflowing.
  • Reduce fuel evaporation by closing the fuel container's vent and keeping it out of direct sunlight.
  • When storing your unit, Fresh Start® Fuel Stabilizer is recommended.

Tune-Up Tips

  • Clean or replace the air filter every three months or after 25 hours of use.
  • Keep the engine tuned, which can add years to a mower and help reduce a mower's emissions up to 50 percent.
  • Change the engine oil after 20–25 hours of use, and recycle the old oil according to your community's guidelines.
  • Use 30W or 10W30 oil to help reduce emissions. Oil should be at the add mark; do not overfill.
  • Keep the mower blade sharp, the underside of the deck clean and engine-running time to a minimum.

Other Ways to Help

  • Mulch or compost your grass clippings, rather than sending them to a landfill.
  • Plant more grass and trees to absorb carbon dioxide.
  • Mow later in the day when the temperature is lower.
