My father came to my house with a 5 ltr drum off Dipetane and told me to put in oil tank. Is this good advice? My boiler seems to be running efficiently .4 days a week it's on thermostat at 19 degrees three days it's set to away as we come in different times. Usually when it hits 19 i turn on boost to 20 after it creeps up to say 19.6 and my oil tank is only dropping an inch a week although this week has been a bit colder so I expect its dropped a little bit more. will the Dipetane affect the amount the boiler burns?
