There's an article floating around somewhere about a mining company in Kansas I think that uses B100 in their underground equipment and they are just giddy over it. I'll post it if I can find it. Not really relevant to original topic tho.By the way, the lifts are 5,000 and 6,000# capacity and have a 3. 3L Tier II Cummins engine to which I am adding a catalytic exhaust (to make them even cleaner running). B20 is supposed to further reduce particulate and CO emissions. We have a demo unit there now and it is CLEAN running, even with just ULSD.
