Fuel-Efficient Mowers: Save Money as Gas Prices Rise

The Fuel Cost Squeeze

Rising fuel prices hit lawn care too. Fuel-efficient mowers are gaining traction, saving owners significant money over the season.

Why Small Engines Are Efficient

• Two-stroke cycle (vs. four-stroke in cars) = half the rotations per power stroke.
• Air-cooled (no liquid cooling system).
• Less heat, simpler maintenance.

Alternative Fuels and Technologies

• Diesel: Higher energy content than gasoline, generally cheaper. Powers many commercial mowers.
• Biodiesel: From vegetable oil/animal fat. Runs in diesel engines, cleaner, renewable, cheap to produce.
• Propane: Cheaper than gasoline, widely available, low emissions. Manufacturers now offer propane-powered models.
• Electronic Fuel Injection (EFI): Kohler's EFI on gasoline engines saves ~$0.75 per $3.00 gallon (25% efficiency gain). Major brands adopting it.

The Future

As fuel costs climb, manufacturers innovate. These alternatives may permanently reshape small-engine economics—even if gas prices drop.
