Good to know, thanks,

OK, but this is not 100% gasoline, the gasoline in diesel is also
used for operation at low temperatures to prevent flaking of the diesel?

I heard about diesels running on their engine oil when they get real hot...
so the only way to stop it is to block the airinlet... we have a phrase
for this but i can't translate it very well, we call it the same as a horse
that's out of control and takes off...
