Diesels have the advantages you qouted but have two large disadvantages. They are very messy (much more so that glow) and the fuel is not readily, avialable although not hard to mix. Also the fuel contains ether which is not very nice to smell. Just my opinion but I would stay with glow. I did run deisels about 35 yrs ago when I was looking for more torque (wish the spell check worked). I'm not sure of relative cost for the fuel.
