You can buy small quantities of heating oil from local fuel suppliers, online retailers like Home Heating Oil, or through services like FuelSnap that connect you with providers in your area.
Finding heating oil in small quantities can be challenging since most suppliers prefer delivering 100+ gallons. However, several practical solutions exist for homeowners needing 20-100 gallons to top off tanks or fulfill lease requirements.
Best Places to Buy Small Amounts of Heating Oil
1. Local Fuel Suppliers & Depots
Many oil companies will sell 50-gallon drums if you pick them up directly from their depot. Call suppliers in your area and ask about:
- Minimum delivery quantities (some offer 75-gallon deliveries)
- Will-call pickup options for 55-gallon drums
- Seasonal promotions for small deliveries
2. Diesel Fuel as Alternative
#2 diesel fuel is chemically similar to heating oil. During winter months, diesel often contains kerosene additives to prevent gelling. Key considerations:
| Factor | Heating Oil | Diesel Fuel |
|---|---|---|
| BTU Content | 138,500 BTU/gal | 137,500 BTU/gal |
| Winter Additives | Varies | Kerosene blend common |
| Price | Lower (no road tax) | Higher (taxed) |
For small top-offs, you can safely use diesel from gas stations in 5-gallon containers. Add two-stroke oil (1 oz per 5 gallons) to maintain lubricity if concerned about pump wear.
3. Online Fuel Marketplaces
Services like Fuelster and BoilerJuice sometimes offer smaller delivery options during off-peak seasons. These platforms aggregate multiple suppliers to find the best small-quantity deals.
Practical Delivery & Storage Solutions
Transporting Small Quantities
When handling fuel yourself:
- Use approved 5-gallon fuel cans (Scepter or Eagle brands recommended)
- Place containers in a well-ventilated vehicle trunk or truck bed
- Bring a funnel with a fine mesh filter to prevent debris entry
Landlord Negotiation Strategies
If replacing oil due to lease requirements:
- Photograph the tank gauge as move-in/move-out proof
- Propose paying the cash equivalent for missing gallons
- Offer to split the cost of a minimum delivery
Equipment Considerations
For Oil-Fired Systems
Small quantity top-offs work best with modern burner systems that can handle slight fuel variations. Older boilers may be more sensitive to winter diesel blends.
Alternative Heating Options
For supplemental heat during oil shortages, consider ventless propane heaters or electric options. These can reduce dependence on oil deliveries.
Safety Precautions
When handling fuel:
- Never mix gasoline or alcohol with heating oil
- Store containers away from living spaces
- Use spill mats when transferring fuel
- Keep fire extinguishers accessible
Most importantly, check with your specific oil burner manufacturer about fuel requirements, as some high-efficiency systems have strict fuel specifications that may not tolerate diesel blends well.
