Emission from Briggs & Stratton engines manufactured today average 75% less than 1995 models. In addition, up to half of emission from outdoor power equipment is preventable. Below are some ways homeowners can join Briggs & Stratton's efforts to reduce outdoor power equipment emissions even further.

Fuel Tips

Using the correct fuel is very important when it comes to your mower. Old fuel, or fuel not meant for your mower, may cause problems with your mower in the short and long term. Here are a few tips from the engine experts at Briggs & Stratton that will help your mower run better and longer, all while reducing mower emissions.

  • Use 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, use a good quality fuel treatment like STA-BIL®, the official fuel additive of all Briggs & Stratton® engines.

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.
