Will-call vs. automatic delivery

Every fuel customer in Ohio is on one of these two systems, whether they chose it or inherited it with the house. The difference sounds small — who makes the phone call — but it decides who is watching your tank in February, and who gets blamed when it runs dry.

Will-call: you watch the tank

On will-call, the company delivers when you call and not before. You (or someone in the house) have to physically check the gauge, judge what's left, and call with enough lead time — which in a cold snap can mean several days, because you're in line behind everyone else who waited for the same cold snap.

The upside: you control the timing, you can shop each fill if your tank setup allows it (much easier with heating oil than propane — see tank ownership), and you're never surprised by a delivery ticket.

The downside: the run-out risk is entirely yours. Gauges stick. Teenagers don't report gauges. A tank that "looked fine at Christmas" is empty by mid-January because January burns fuel at roughly twice December's rate in a cold year. When a will-call customer runs out, it's an emergency delivery at emergency prices, possibly with a prime-and-start service call on top.

Automatic delivery: the company watches the tank

On automatic (also called keep-full), the company's computer tracks your usage against the weather using degree-days — a running measure of how cold it's been — and your household's burn rate, learned from your delivery history. When the math says your tank is approaching the refill point, a ticket prints and the truck comes. Increasingly, companies skip the math and put a cellular monitor on the tank that reports the actual level.

The upside: you stop thinking about the tank. Deliveries land on efficient full routes, which is partly why automatic customers sometimes get better per-gallon treatment, and if the company's system genuinely fails and you run out, most reputable companies will treat the run-out as their mistake — emergency fuel and the service call on them. Ask yours whether that's their policy, in those words.

The downside: you give up timing control. A delivery arrives when the system says so, and you pay the price in effect that day. You also have to tell the company when your usage changes — a new baby, a wood stove, an empty-nester winter in Florida — or the degree-day math will be wrong in one direction or the other.

Which one fits?

• Automatic fits most full-time-occupied homes, anyone who has run out once and sworn "never again," and anyone whose tank is somewhere they don't naturally walk past.
• Will-call fits disciplined gauge-checkers, part-year residents, and oil customers who genuinely shop price per fill and have the tank access to do it.
• The hybrid that works: automatic delivery plus a tank monitor, if your company offers one. The monitor removes the guesswork from the company's side too.
