5Fill Your Oil / LPG Tank
If you live on the grid, this is very important, and you avoid the problem of running out of oil if it snows for days or weeks. If possible, avoid buying oil during the coldest months when increased demand will drive up prices; set a date in your calendar for summer or any unseasonably warm period when suppliers usually sell oil at lower prices to reduce the surplus. Remember, you can store oil for up to two years.
