Running out of heating oil in the dead of winter is a nightmare scenario for any homeowner. While waiting for a heating oil delivery is the ideal solution, sometimes emergencies require alternative solutions. This leads many to wonder, “Can I Put Diesel Fuel In My Oil Tank?” This comprehensive guide will answer that question and provide essential information on using diesel as an emergency heating fuel.

Confirming Your Heating Oil Level
Before resorting to diesel, it’s crucial to confirm that your heating oil tank is truly empty or below critical levels. Don’t rush into using an alternative fuel unnecessarily.
Checking the Oil Gauge
Most heating oil tanks have a floating gauge that indicates the oil level. To ensure it’s working correctly, remove the plastic cover and gently push the gauge down. If it returns to its original position, there’s still oil in the tank. If it stays down, you’re likely out of oil.
Manual Oil Level Check
Alternatively, use a yardstick to manually measure the oil level. Insert the yardstick into the tank’s fill tube. Each tank has a specific critical level indicating when to refill, usually around one-quarter to one-third full. Consult your tank’s manufacturer for precise guidelines.
Using Diesel in an Emergency
If your tank is empty or critically low, diesel can serve as a temporary heating fuel alternative. However, it’s essential to understand the implications and safety precautions.

Diesel vs. Heating Oil
Diesel fuel burns hotter than heating oil. While acceptable for short-term use, prolonged use can damage your heating system. Limit diesel use to 5-10 gallons per day and only for as long as necessary until your heating oil delivery arrives.
Safe Handling and Storage
Always store diesel in approved, properly labeled yellow containers. While diesel can be stored safely for up to six months, it’s best to use it as soon as possible. Dispose of any unused diesel through your local hazardous waste collection center.
How to Use Diesel in Your Heating Oil Tank
If you must use diesel, follow these steps:
- Turn Off the System: Completely shut down your heating system using the thermostat control.
- Add the Diesel: Carefully pour up to 10 gallons of diesel into the tank. Mixing diesel with residual heating oil is preferable as it avoids the need to bleed air from the lines.
- Allow Sediment to Settle: Let the tank sit for a few minutes after adding diesel to allow any sediment to settle.
- Restart the System: Turn your heating system back on.
Dangers of Low Oil Levels
Running your heating system with low oil levels risks a complete system shutdown. Sediment buildup at the bottom of the tank can clog the fuel line, leading to a sudden shutdown even before the tank is entirely empty.
Emergency Heating Oil Delivery
The best solution to avoid using diesel is to schedule a heating oil delivery as soon as possible. Contact a reputable heating oil company for emergency delivery services to minimize reliance on alternative fuels.
Preventing Future Emergencies
Consider enrolling in an automatic oil delivery service to prevent future fuel shortages. This service ensures your tank remains adequately filled, minimizing the risk of running out of oil during cold weather.
Conclusion
While diesel can be used as a temporary fix in a heating oil emergency, it’s not a long-term solution. Understanding the risks and limitations of using diesel is crucial. Prioritize scheduling an emergency heating oil delivery and consider automatic fill services to avoid future crises. Contact a qualified HVAC technician if you have concerns or require assistance with your heating system.
