275-gallon oil tank: cost to fill

225 usable gallons at $5.54/gal = $1247 national average fill. EIA

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
