Will shandy of unleaded mixed with 20% diesel be usable in Series I

It should be fine.

These engines were produced around the same time in England when petrol was becoming more heavily taxed, which led to the creation of tractor vapourising oil, or "power kerosene" as we knew it. I have run a Ferguson 20 series on homemade "power kerosene" of 50-50 diesel and petrol and it ran without any problems.

Be aware though that in order for the Diesel to vaporise correctly the engine needs to be hot. TVO that was up to 80% diesel had trouble working in a petrol engine unless the tractor was ploughing or pulling hard.

OK - looks like I'll give it a go and see what happens. If I have to drain it all out again it won't be the end of the world, I was just confirming that it wouldn't do any damage to the engine (a la glazed bores etc).

Thanks for all the info.

Add more ULP to dilute it and just use it in a your other vehicles (if they don't have O2 sensors and cats.)

I remember an old Hillman at the Hillman Club where a bloke added diesel by mistake (he owned a diesel LR). It smoked a lot but it didn't harm it. It burned and didn't end up in the sump.

What sort of ratio do you guys think a 3.9 V8 would handle?

In case I have to know one day..

the hydrogen in H2O is already oxidised and has no potential as a fuel.

It will however convert thermal energy to pressure very effectively in the combustion chamber (google: water injection)

When running in hot conditions (summer sand dunes and other hard work) I frequently put 30% diesel into my 2.25L. This reduces the vapour locking problems as it raises the boiling point. If it starts to knock, I retard it a little bit. Any higher than 30% and it becomes hard to start when cold. The higher the compression ratio, the less diesel you can run, or the more that you must retard the ignition. If you were to run straight diesel (like in a power kero tractor) then this is when it dilutes the oil in the sump. Instead of doing oil changes at 250 hours you do them at 150 hours. I have a friend who runs a "petrol" truck on 90% diesel when off the road, but warms it up on petrol first.
