So I've got my big 275 gallon tank of heating oil, which currently has about 270 gallons in it, thanks overpriced off season fill up.
But i also have about 8 gallons of used cooking oil.
If I run the cooking oil through say cheesecloth, would it dilute enough in the 275 gallon tank to burn?
I did do some searching and just kept getting ads for waste oil burners and 15 year old forum posts where people wanted to run entirely on cooking oil.
I'm just looking for a more convenient than bonfire method of getting rid of my used cooking oil, since I don't generate nearly enough for any of the waste oil/bio diesel guys to be interested in.
That is a good question. I hope that someone has a good answer for you.

Curious to see the responses here. My gut would tell me it is all about the comparative smoke and flame temps of the oils. Fuel oil - from memory is close to Jet A and has a fairly high flame / smoke point. would assume considerably higher. I can't imagine 8 gal into 270 beng an issue but curious now.
As long as it doesn't settle to the bottom and congeal, blocking the filter, it should work fine. How cold does your oil tank get?
As far as burning, no problem, I should think.
Maybe try a mix of cooking oil and fuel oil in a quart glass jar to to see if it settles, or doesn't play nice in the cold etc..
Ive poured cooking oil into the following things with no adverse affects:
- Heating oil tanks (along with old gasoline and drain oil, as long as its reasonably dilluted and clean)
- The fuel tanks of my 6.5 Diesel and my Cummins and my 7.3 Powerstroke
- A hole I dug in the ground behind the garage
Of the three options I would do the first two.
In reply to Streetwiseguy :
About 50 degrees in the winter. Tanks pretty close to the furnace and even opening the garage door to let the kids on the bus, it stays t shirt weather along that wall.
in reply to fasted58:
that's a good idea, I'll have to give it a shot over the weekend.
I don't think #2 fuel oil is as processed as diesel. But it's better that your furnace taking a sip of water.
