Heat with Diesel If You Run Out Of Heating Oil In Your Tank

Diesel fuel used in diesel powered vehicles and other engines, is basically No. 2 home heating oil. The only difference is that home heating oil has a dye added to it that distinguishes it from untaxed or lower-taxed fuels. The higher-taxed diesel fuels are used for over-the-road vehicles. However, if an emergency were to arise such as the home running out of heating oil, diesel fuel could be purchased at the local service station. Homeowners can substitute diesel fuel for home heating oil in any quantity necessary while awaiting delivery of home heating oil.

Step 1: Call Love Energy Fuel

Understandably, the first thing to do when you have no more heating oil is call Love Energy Fuel for a delivery. Keep in mind that this will take time, mainly when snow has blocked many roads leading to your home, you will have to use an substitute fuel, such as diesel.

Step 2: Go to your Local Gas Station and BUY DIESEL” ***NOT GASOLINE**

Look for a gas container  or buy one at your local hardware store. The ideal container should hold at least five+ gallons of fuel. Since you do not know how long the heating oil company will take to deliver the fuel, you should buy as much diesel as possible. 


Step 3: Fill Up Your Oil Tank

Preferably, you should try to add the diesel fuel to your tank prior to your furnace running completely out of oil. If you do run out all the way, you will have to be able to bleed all of the air out of the oil line to get it back up and to run again. This will usually entail making sure that the filter, nozzle and the oil pump are all clear and taking the time to ensure that no sludge makes its way through that could cause any blockage. When you get back home, turn the home thermostat that controls the oil furnace to the “off” position, fill up your oil tank with the diesel and give it 10 minutes to settle in the tank. This will allow any sediments and impurities to settle at the bottom of the tank, thereby giving the fuel intake line access to clean fuel.

Step 4: Restart The Furnace

Restarting the furnace can be as simple as pushing the red reset button on your furnace. You may need to press the reset button several times to bleed the fuel line and restart your furnace. Once the heater has turned on, your home will be heated normally. The fuel should be enough to last you until the heating oil company delivers the heating oil you ordered.

In some cases, the fuel supply system of the furnace may need manual bleeding. To perform this procedure, you will need to have a pipe wrench a quarter-inch nylon tubing and a clean container.

Start by shutting off the furnace through the toggle switch on the unit. The next step is to locate the bleeder valve on the furnace’s oil pump. This component looks like a grease fitting and can be opened or tightened using a 1 cm wrench. Once you have located the bleeder valve, insert the 1/4 inch nylon tubing. The tube should lead into the clean empty container.

Next, turn on the furnace and loosen the bleeder valve using the wrench. Be sure to hold the nylon tubing inside the container to ensure  diesel does not spill. At first, the fuel is going to gurgle out of the tube due to the presence of air. After a couple of seconds, however, only oil will stream out of the nylon tubing. When you notice this, use the wrench to tighten the bleeder valve before restart the furnace and cleaning up the work area.


How To Locate and Read An Oil Tank Gauge


Chances are your oil tank is in the basement or outside somewhere close to the house. It’s a big metal tank.


Sticking up on top of the oil tank is a clear tube with a float inside. On the outside, it is marked: F, ¾, ½, ¼, (from top to bottom).Those numbers tell you how much of the tank is full. The float goes up and down according to how much fuel is in the tank. So, if the float is aligned with the ½ mark, the tank is half full. If the float is at the bottom of the tube or not visible, then the tank is empty or close to empty.



A standard residential oil tank holds 275 gallons. Based on that size, the following readings indicate that your tank contains approximately this many gallons:

  • 1/8 = 40 gals
  • 1/4 = 70 gals
  • 3/8 = 100 gals
  • 1/2 = 130 gals
  • 5/8 = 160 gals
  • 3/4 = 200 gals
  • 7/8 = 240 gals
  • “full” = 265 gals


Most houses have a 275-gallon tank. When full that tank holds close to 225 gallons. If the gauge reads ½ you have about 110 gallons of fuel. At ¼ you have about 55 gallons and at ¾ about 170 gallons. It is recommended to call for a refill when you're around the 1/2 and 1/4 mark in the clear tube.


At an outside air temperature of 32° (average over a 24-hour period) the typical 2500 sq.ft house will burn about 6.5 gallons per day. So if you have half a tank (110 gallons) and it’s cold out you’ll use up that fuel in about 17 days. If you’re not on automatic delivery you need to give us 5-days’ notice so you wouldn’t want to wait more than about 10 days to call for a delivery.


Home Heating Oil Additive?

Heating Oil Additive Promotes Fuel Efficiency

When should you use a Home Heating Oil Additive?

The answer… before a problem arises and definitely when you see the first signs of a problem.
If you use oil heat then you are most likely familiar with problems such as water and/or sludge build up in the bottom of your oil tank. The problem then extends from your tank to your furnace producing clogged nozzles.

Sludge also causes dirty filters and strainers which cause more soot that produce more smoke. This all makes the furnace less fuel efficient. With years of neglect these conditions will shorten the life of parts for the furnace and ultimately the furnace itself.

You need a home heating oil additive product that does these 4 things:

  1. Disperses water so that any amount that collects in the oil tank, will be changed into a substance that is combustible.
  2. Gets rid of sludge by dissolving sludge into a substance that will not clog nozzles and filters.
  3. Eliminates sludge so that fuel oil reaching the nozzle is clean reducing soot output and smoke.
  4. Prevents waxing and gelling that can occur in very cold weather. These conditions clog the fuel lines and fuel filters so that fuel oil from the tank can’t get through.

Which product does all that?

There are many options on the market but we use the most effective“Hot 4 in 1” Home Heating Oil Additive.

It’s a very popular product because it eliminates water and sludge build up which causes clogged nozzles, filters and strainers, and makes furnace burn fuel more efficiently.
