I just posted a link to a blow torch warming up where one can see the difference between a fuel burning as a liquid and as a gas.
The same trick was used on old tractors that started on petrol, then changed over to paraffin once warmed up.
NB: that these engines had a very low compression ratio, so the octane rating of the fuel was of no consequence...
In today's engines one would have to use Diesel ignition.
ie:
Spray in the fuel at the right time to auto ignite, rather than a spark at the right time.
My point being that:
No; you don't have to use petrol or diesel in the steam reformation process.
Any old oil/s etc should work to some useful degree.

But it does seem that methanol works best at the temperatures attainable from waste exhaust heat.
