Simple refill planning formula
Track how many gallons you used between two fills, then divide by days elapsed to get your average gallons per day. As temperatures drop, increase your safety margin and reorder earlier.
How to avoid run-outs
- Reorder before the tank drops below about 1/4 in colder months.
- Set a recurring reminder once per week during peak winter.
- Keep your fill pipe and driveway clear for delivery access.
Tudor Tip
Drafty windows and doors can account for up to 15% of your home's heat loss. Installing simple weatherstripping is an inexpensive, weekend-friendly way to lock in the warmth and extend the life of your heating oil tank between refills.
