TVO

Post by cobbadog » Thu Feb 13, 2020 5:15 am

TVO, tractor vaporising oil can be used in a few different make of tractors but I was just now reading in a UK based tractor maazine that you must mix your TVO when filling the dedicated tank.

Obviously by the sound of this it must be mixed with something but what?

For years I thought that TVO was the same as what we call kerosine but this must be wrong.

So exactly what is TVO and what do you mix it with please?

I have found the following informations: TVO is a blend between Kerosene and Leaded Petrol here in Australia it was called Power Kerosene which is no longer made.The ratio given too me by the Oil company to make my own Power Kerosene is:
2/3rd Leaded Petrol
1/3rd Kerosene

So, TVO is a mixture of Kerosene and Petrol and this mixture is not available anymore, you have to mix it yourself. You do not add anything to TVO, but you make TVO. There are different recipes for mixing the two components and some use a small amount of 2-stroke oil as a third component.

A license is required in Britain to legally use kerosene based fuel if the tractor is driven on public roads. This license is obtainable from The DBTC .
DB tractors with engines built for this type of fuel do not require additions but if petrol is added better performance is obtained.
The inlet manifold should be in good condition internally if kerosene is used.

Thank you both for the informative replies. I have no interests in using TVO as the kerosine prices here are almost dearer than the petrol as it is not sold in bulk any more.
In the Tractor Farming Heritage Magazine they described it as being 'mixed' before you add to the fuel tank and this is what prompted me to ask.
The term of Power Kerosine is something that was and can be used in some of the old stgationary engines which were mostly hot bulb engines like Tangye. Talking to woners of these engines they tend to purchase when ever possible out of date aviation fuel and mix diesel with it. There seems to be no rhyme or reason as to what the ratio is as some claim one ratio and others another to get their engines to run smoothly.
Thanks again for the information, I appreciate it.
