How Much Oil Do You Burn In A Typical Winter Season??

[BigFish]

I consider myself fortunate that over the past 3 winters I have not had to pay a penny for oil to heat the house as I got enough from my former business to keep me warm....but those days are over and after this winter I will be paying for it as that business is over! However I feel fortunate that my house only burns about 1 1/4 to 1 1/2 tanks (325-350 gallons) of oil in a typical winter season by my calculations! Thats not too bad! Just curious how much others typically go thru in a winter???
