TVO is neither fish nor fowl....this from the Friends of Ferguson Heritage...
RECIPE FOR TRACTOR VAPORISING OIL
There must only ever be 2 ingredients in TVO
- Petrol (unleaded is absolutely fine for a Ferguson tractor) 98 Octane
- 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 petrol and 1 heating oil comes out at 59 Octane
- 2 petrol and 1 heating oil comes out at 72 Octane
- 1 petrol and 2 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 is provides a good guide line
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.
