Tractor Vaporising Oil (TVO) can be mixed using petrol and heating oil. FOFH give some good guidance on mixing TVO.
This is the method and ingredients they recommend….
There must only ever be 2 ingredients in TVO1. Petrol (unleaded is absolutely fine for a Ferguson tractor) 98 Octane.
2. 28 Second Heating Oil 20 Octane.
Aim for an Octane value between 55 and 70.
55 if doing very hard work
70 if doing topping and the like
To give you some idea of the sums:-
1 part petrol and 1 part heating oil comes out at 59 Octane.
2 parts petrol and 1 part heating oil comes out at 72 Octane.
1 part petrol and 2 parts heating oil comes out at 46 Octane.
Petrol on its own is suitable for road runs (with the heat shield removed).
Octane is not the only factor, but it provides a good guide.
Diesel fuel is designed to cause ignition by compression and will encourage pinking. It is not designed to burn in TVO tractors, and no upper cylinder lubricant is required in these tractors, so do not use anything other than petrol and heating oil.
Using fuel which does not burn completely will destroy the lubricating properties of the oil and that (in a Ferguson TE tractor) will result in wear to the cam shaft bushes and then loss of oil pressure from cam shaft bushes. Loss of oil pressure will, then result in damage to the crank shaft. Lubricating oil in a TVO tractor’s engine should be changed according to the Tractor Instruction book.

With regard to your TVO mixture this seems to differ widely from that employed by friends of mine. The most common mix seems to be 20 litres of kerosene, five litres of petrol and 1/2 litre of two stroke oil. Some use diesel instead of two stroke oil but this seems a pointless excercise while a few even use straight kerosene on Case tractors with very good vaporisers, temperature guages and efficient rad blinds.

Hi I have a 1950 TEA TVO 20 litres heating oil. 5 litres of petrol . I use it for potato growing and ploughing, also pulling a trailer. Runs a treat .
I have a 1950 TED Massey and we unfortunately cannot get Power paraffin / heating oil easily in South Africa. Can anyone give a recipe using illuminating paraffin ? Even avgas (aviation fuel) is becoming more difficult to get in Africa nowadays. any ideas?
heating oil in this sense is standard grade kerosene,also known as 28 second oil.diesel is different and known as 35 second oil when used for heating.for over 20 years i have used a mix of 8 parts kero to one of petrol.this mix i got from an oil company who used to sell it.they had it tested and it came up to 50 octane which is what the tvo fergy was designed to run on.if you look on a fergy sales leaflet it refers to the tvo tank as ‘tank for 50 octane fuel’have also used in tvo david brown cropmaster and stationary engines.i know of people who plough with standard fordsons who use straight kerosene without problem
In Portugal he have diesel Heating,it must be the same as heating oil or not?
i assume the heating oil is Kerosene oil? i have just aquired an old ferguson 20 tvo, i intend working it a little, cleaning yards, moving stuff etc. this mix sounds good, i hear of people mixing in engine oil etc, dont see how that would burn, those little tvo tractors run hot!
Please can you tell me what is these so called heating oil,is it paraffin or what.
And What is the fireing order of the Ferguson on my tractor’s name plate is this number TED 385065
Hi, the TVO recipie listed above by Bob Callaby is very nearly identical to what i have been using for 16 years now in my 1947 ferguson, never had any problems and it used for driving powerwasher, pulling boat to and from beach, and driving to vintage rallies. Since its worked so well for the 16 years I have owned it im inclined to say its a good recipie.
