How much oil is consumed in the United States? Only a small amount of crude oil is directly consumed in the United States. Nearly all of the crude oil that is produced in or imported into the United States is refined into petroleum products such as gasoline, diesel fuel, heating oil, and jet fuel, which are then consumed. Winter time, using the heating, hot water and cooking for about 3-4 hours per day, I use 1000 litres in 3 months. My boiler is supposed to be very efficient for it's type. I guess 10 -12 litres a day would not be unusual. Pants is'nt espeically with oil over 40p a litre. Approximate Daily Heating Oil Usage vs Temperature F For example, if the outdoor temperature is 15F you can expect to use about 7.8 gallons of heating oil in 24 hours; if it’s 20F outside, you can expect to use about 7 gallons in 24 hours.
