#2 Diesel is the same thing as Home Heating Oil. HHO is not tested for a Cetane rating and #2 Diesel is, but beyond that there is little difference.

Right now everyone is filling up on HHO and throughout the Midwest farmers are loading up on Diesel to finish up in the fields before winter.

This does not take place every winter, but over the past 35 years I have seen it do it several times.
