Funny oil bill

[BDG]

Heating oil generally (you can get different grades) is pretty poor at lubricating, and diesel is used as a lubricant in fuel pumps. I would not run a common rail engine on heating oil, but an older diesel should have no problems as long as you add a lubricant to the heating oil, heard veg oil at 20:1 does the trick (the veg oil being the 1).

I can get fresh veg at around 88p/l - what is heating oil costing these days?

As for tanks being tested, your fuel will only be analysed if you fail a dip test and they see the dye I am informed.

If you are running on anything other than pump fuel, contact HMRC and tell them and ask what arrangements you need to make for paying duty.

Post SHTF, run on what you like. If you have a good diesel engine it will run on a lot of things. Look into making fuel too - you can clean and refine many things, from the well known used chip oil to sump, gearbox and diff oil and it is not difficult if you know what you are going. Easy backyard chemistry.
