Costumers often wonder how much oil to order to take advantage of our discount pricing. We have placed this helpful chart on our website for your convenience. A standard residential oil tank holds 275 gallons. To order 150 gallons or more, please call us when your tank reads 3/8 full or below.
The standard tank appears to have been 26 gallons, although there's a bit of confusion between US and British sites about whether that was 26 US gallons (which would seem logical, coming from a US manufacturer) or 26 Imperial gallons (which would equal 31.2 US gallons).
