Additionally, we’ll explore how mixing oil and fuel for small engines works, and I’ll share some useful tips for storing fuel for these engines.

Tips for Fuel Storage

  1. Use the Right Container: Always store fuel in a container designed for gasoline. These are typically made of high-density polyethylene (HDPE) and are red in color for easy identification. Avoid using old food or drink containers, as they can cause chemical reactions or are not designed to prevent fumes from escaping.
  2. Label Containers: Clearly label each container with the type of fuel and the date of purchase. This helps in identifying the fuel type and avoiding the use of stale fuel.
  3. Limit Quantity: Store only as much fuel as you will use within a short period (ideally within 30 days). This is because gasoline can degrade over time, especially if it contains ethanol.
  4. Keep It Cool and Dry: Store fuel in a cool, dry place away from direct sunlight. Sunlight can increase the temperature and cause the fuel to expand, potentially leading to leaks or spills.
  5. Avoid Heat Sources: Store fuel away from any sources of heat or sparks, such as furnaces, water heaters, or power tools. This reduces the risk of fire.
  6. Use Fuel Stabilizers: If you need to store fuel for an extended period, add a fuel stabilizer to prolong its shelf life. This is particularly important for ethanol-blended fuels, which can absorb moisture and degrade faster.
  7. Regularly Check for Leaks: Inspect your fuel containers regularly for any signs of leaks or damage. Replace containers that show signs of wear, such as cracks or fading.
  8. Ventilation: Ensure that the storage area is well-ventilated. Fumes from gasoline can accumulate and pose a health and fire hazard.
  9. Child and Pet Safety: Keep fuel out of reach of children and pets. Store it in a locked cabinet or shed if possible.
  10. Dispose of Old Fuel Properly: Never pour old or contaminated fuel down the drain or on the ground. Check with your local waste management facility for proper disposal methods.

Examples of Fuel Storage

  • Portable Fuel Containers: These are ideal for small amounts of fuel. Look for containers with a spill-proof system and a vent for smooth pouring.
  • Safety Cans: These are designed for safe storage and easy pouring. They often have features like flame arrestors and pressure relief.
  • Above-Ground Tanks: For larger quantities, above-ground tanks can be used. They should be placed on a stable, flat surface and equipped with proper venting and spill containment measures.
  • Underground Tanks: Used for very large quantities, these tanks are less common for individual use and more for commercial purposes. They require professional installation and regular inspections.

Real-World Example

  • A gardener stores gasoline for their lawn equipment in a 5-gallon HDPE container. They add a fuel stabilizer since they use the fuel intermittently over a few months. The container is kept in a cool, dry corner of their garden shed, away from direct sunlight and any electrical equipment. They check the container monthly for any signs of wear or leaks.

Fuel Recommendation for High Altitude Climates

As a mower owner, you’ll find that high altitude climates can significantly affect your Bad Boy mower’s fuel efficiency and performance. The fuel recommendation for high altitude climates is slightly different than at sea level.

  1. Octane Needs: Higher altitude means less oxygen, which may affect the combustion process in your mower’s engine. Using gas with a higher octane rating can help maintain performance.
  2. Fuel Stability: At high altitudes, fuel can evaporate more quickly. A fuel stabilizer can counteract this and keep your gas fresher for longer.
  3. Ethanol Content: High-altitude areas tend to be drier, and ethanol fuels can attract moisture, leading to potential engine issues. Opt for lower ethanol fuels, if possible.

Mixing Oil Fuel for Small Engines
