I'm sure there is a farm foods around here somewhere. Tesco are still doing their offer, but most the time, they seem to have run out.
I've just mixed a jamjar of half solid oil, and half diesel. It was clear thin liquid this morning. I also put 10% RUG in a sample, and that had gone solid.
They are forcasting -3 later in the week, so I will see what the 50/50 mix looks like then.
For me, its cheaper to do the mix, than buy new oil, if it will stay liquid.
Now running on a 50/50 of reasonably liquid oil and diesel. Got about 50 litres of it, so hopefully will last me till it warms a bit again. It will last me if this snow keeps up, coz I wont be going anywhere..........
