Diesel is still cheaper than jet fuel. Or isn't it? I've been too
afraid to go to the pump the past few days

One thing I have to ask, is if that engine is rated to use Jet A? From what
I have read, many are not, because some injector pumps need the lubrication
that diesel provides, that Jet A does not have. If the pump is not able to
handle the Jet A, it will quit in fairly short order.
