275-gallon oil tank: cost to fill

Nameplate vs usable

The 275-gallon nameplate is the tank's water capacity. Heating oil fills to ~80% safe-fill (~225 usable gallons), leaving room for thermal expansion and the vent-whistle margin. Dealers deliver to the 95% shut-off (~260 gallons) only on empty calls, and that's measured from the truck meter, not the tank gauge.DOE

How often does a 275 refill in a typical winter?

A 1,500 to 2,000 sqft Northeast home burning 700 to 900 gal/season refills a 275 three to four times between October and March. Auto-delivery dealers schedule based on degree-day burn rate, typically every 4 to 6 weeks in deep winter.
