⚠️ Important Disclaimer
This calculator provides estimates only and should not be relied upon as exact measurements of your tank capacity or current oil levels.
Actual tank capacity and gauge readings may vary based on:
- Tank installation angle and positioning
- Gauge accuracy and calibration
- Tank age, shape, and manufacturer specifications
- Sediment or sludge buildup in the tank
- Temperature affecting oil volume
Limitation of Liability: TryCODFuel.com is not liable for overfills, tank damage, or delivery issues resulting from use of this calculator. Always verify gauge readings and consult with your oil delivery professional. Never fill tanks beyond 90% capacity to allow for oil expansion.
Safety Recommendation: If unsure about your tank capacity or gauge reading, contact a licensed heating oil professional for an in-person inspection.

Tank Capacity Tips
- Never fill your tank to 100% - leave 10% space for oil expansion in warm weather
- Check your gauge regularly during heating season (at least weekly)
- If your gauge seems stuck or inaccurate, it may need replacement
- Order oil when your tank reaches 1/4 full to avoid emergency deliveries
- Know your tank size - it's usually on a label or stamped on the tank
- Schedule annual tank inspections to check for leaks and corrosion
