This is a very simple formula just mix the listed ingredients at the ratio shown.
25 litre of Heating Oil (Kerosene) current price approx 31p per litre
1 litre of Duckhams Hyper grade (Diesel Oil Engine)
Heating Oil Burns at 29 seconds
Diesel Burns at 33 seconds
To slow the burning down, diesel engine oil is required, in the ratio listed above
Duckhams hyper grade diesel oil also has the green dye, which colours the kerosene, the same as the fuel from the pumps.
This does work very well, do not use in a road vehicle, if you get caught they will tke your vehicle away, I know this to be true. Will be fine in a TM.
For road vehicles, the biodiesel is best, if you declare and pay the duty, we are looking at 15k a year in savings.
