Only with diesels... and it eats `em up, along with everything else.
Don't waste your time with methanol.

Most brass injectors fare better than one might expect with alcohols,
but methanol still causes big problems, if only because there's
virtually no lubricity in the fuel--it eats injectors, pumps and engine
internal parts and who knows what else. The problem is not just the
injectors.  It's the whole system. We put steel-geared transfer pumps on
buses running methanol and they were gone in a matter of days--finally
helped the problem by installing glass-filled nylon gears in the pumps. 
Alcohols cut oil's lubricity, so you get top-end and ring wear at an
accelerated rate. A better possibility is ethanol--there are lubricating
additives for that fuel which are proven to work, and the corrosion
problems are fewer with ethanol.  Further, it's easier to get than
methanol (in denatured form), and in terms of price/BTU value, far
cheaper.  
Cheers.

My other Triumph doesn't run, either....
