Oil burning engines suffer the same fate as coal fired engines. The sulfur in
petroleum soot turns to sulfuric acid when exposed to moisture.

Greetings, When the smokebox was opened on 3006 here in the burg, we found

the ash was shoveled out and a plate tack welded over the stack. I don't
know how oil burners fare in the long term but coal burners stand some
concern........Bill----- Original Message -----
