if you have a mate or yourself with oil central heating stick it in the bottom of the tank and fill it up with heating oil and you will be grand.
Same goes with Jet A as well.
You might clog up the burners though with the lead but never heard of anyone having any problems.
On a note i killed the CAT on my car with avgas and fished all the bits out with a coat hangar. Passed the next 3 emissions test during the MOT only issue was if it didn't start first go it flooded and you had to pull the fuse on the fuel pump to get it going which wasnt an issue to be honest until an auld granny collapsed in tesco car park when she back fired like an engineer on sprouts.
