Jet A1 is a little bit cheaper, but it need oil addition (2 strokes oil is

Have you heard of anyone cutting Jet A like your describing? I would
expect those engines are quite sensative. I'd be really nervous about
fuel/oil ratios doing that!

I recognize that they don't fly, but trucks have mixed kerosene
(sometimes called #1 fuel oil) and diesel (sometimes called #2 fuel
oil) in cold weather.

One of the company's that my father dealt with had a small kerosene
tank which they used before shutdown and to start.

It is interesting that #2 has more BTU/gallon than #1, so mileage is
slightly better on #2.

The lubricity issue is one that I asked a buddy of mine aobut when
Thielert said their "auto based" engine would run JetA ...

Enquiring minds would like to know more.

I have a picture somewhere of a Twin Otter in a small arctic community being
fueled from a truck clearly marked "Furnace Oil". Apparently these areas get one
boatload of fuel each summer to last the year, and it is Arctic Diesel or "P-50",
suitable for aircraft, diesel generators, stoves and just about anything else.
Normal diesel is definitely not used in aircraft because it can get cold at
altitude and the fuel jells.
