Sounds like you had better get some 3in one oil in the bushings before it seizes up. lc
In general, yes. But they've put big taxes on diesel. I have also converted an #2 oil furnace to reliably burn the motor oil from our van fleet
lack of oil
If you are talking about standard #2 diesel fuel oil and not motor oil and you have a #2 oil fired furnace or boiler in the home the answer is yes .
To add the sae 10 non detergent oil to your furnace blower motor you will have to open the motor section.
Furnace oil is the source of fuel used by the heating system to create a consistent warmth when required.
The oil that is burned by furnaces is mostly #1 or #2 fuel oil
It would depend on the type of burner in your oil furnace and the type of jet fuel. I recommend that you contact the manufacturer of your furnace first.
Fuel oil and diesel fuel are similar, but they are not the same thing. Each has its own ASTM standards. Check with your heating oil supplier. If you don't trust his opinion, check with the manufacturer of your furnace. Those are the two groups of experts.
If the motor has oil ports you can put in a few drops of oil. If the motor has sealed bearings you will need to replace it.To fix a squeaky furnace, you need to add oil to the motor bearings. In some cases it could also be due to the fan, which would then need to be replaced.
No you cannot. Old motor oil contains harmful additives that can be released back into the atmosphere and can make you sick. Don't do it.
Petroleum Is a fossil fuel
The kerosene is a lighter oil. I think you would get more BTUs out of the heating oil. Just make sure that you are using the right fuel for the furnace that you have. Most now days would take heating oil.
