What to Expect on Heating Oil Delivery Day

First delivery at a new house, or just never paid much attention to the process? Here's what happens from the moment the truck pulls up to the moment you verify your delivery ticket — and what to do if something seems off.

You Don't Need to Be Home

In most cases, you don't need to be present for a heating oil delivery. The driver will locate your fill pipe (typically a capped metal pipe on the outside of your house, often near the basement), connect the hose, and pump in the oil. They'll leave the delivery ticket at your door or in a standard spot they've established with your account.

If this is your first delivery at a new address, it's worth being home once to show the driver the fill pipe location, any access issues (locked side gate, low-hanging wires over the driveway), and where you prefer the ticket left.

What the Driver Does

1. Locates the fill pipe: The exterior fill pipe is usually labeled "OIL" and has a standard 2-inch female fitting. It connects via underground (or interior) pipe to your storage tank.
2. Checks the vent: Before filling, a driver should verify your vent pipe (a separate small pipe, often near the fill pipe) is unobstructed. The vent allows air to escape the tank as oil fills it. A blocked vent can cause a dangerous pressure buildup.
3. Connects and fills: The hose connects directly to the fill pipe. The pump meter runs continuously and measures gallons delivered to the hundredth of a gallon.
4. Listens for the whistle: The vent pipe has a small float device (whistle vent) that emits a sound as oil approaches the top. When the whistling stops, the tank is full. This is the standard way drivers know to stop — not the meter.
5. Disconnects and prints the ticket: The driver disconnects, caps the fill pipe, and prints your delivery ticket from a handheld device or truck terminal.

What to Check on Your Delivery Ticket

The delivery ticket is your receipt. It should show:

• Gallons delivered: This is the meter reading from the truck's calibrated flow meter. It's regulated by state weights and measures — the meter is tested annually.
• Price per gallon: Should match what was quoted when you scheduled the delivery. If you used a competitive bid service, verify this number.
• Total charge: Gallons × price per gallon. Some tickets also show a delivery fee if applicable.
• Date and delivery address
• Driver/truck ID number

How Gallons Are Measured — And Why You Can Trust It

Oil delivery trucks use flow meters that are tested and sealed by state weights and measures inspectors. In Connecticut, meters must be tested annually and any unsealed meter is illegal to use for commercial delivery. You can't easily verify the gallons yourself (you can't see inside the tank), but the regulatory framework means meter fraud is uncommon and dealers face serious penalties for it.

If you ever want to cross-check: note your tank gauge reading before and after a delivery. A 275-gallon tank at 1/4 full holds about 55 gallons. A fill adding 200 gallons should bring it from 1/4 to around 95% full. Tank gauges are approximate (±10%), but gross discrepancies are worth flagging.

Common Delivery Day Issues

• Driver can't access the fill pipe: Make sure nothing is blocking the fill pipe — parked cars, stored equipment, overgrown shrubs. In winter, keep the area around the pipe shoveled out.
• Wrong price on ticket: If your quoted price and delivery ticket price don't match, call immediately. Reputable dealers will correct billing errors. If you booked through a competitive bidding service, contact them directly — they often handle this on your behalf.
• Vent pipe issue: A driver who notes a blocked vent should not complete the fill. If they do fill anyway and your vent is blocked, you risk oil being forced back through the vent opening. Address vent issues before rescheduling.
• No ticket left: Most dealers leave a paper or digital ticket. If you don't receive one within 24 hours of your scheduled delivery, contact the dealer to get a copy — you need it for your records.
