Since I may soon by aquaring a 7.3 IDI F350 I was thinking about starting up using WMO (after i get all the basic upkeep done) to help on fuel costs however around here you have to pass emissions (every 2 years for gassers at least think the same for diesels) so was wondering if running WMO affects your emissions negativly or if I could still run it come emissions time (vs running a tank of straight diesel long enough to do emissions). Semi unrelated but any diffrence in using Diesel vs Kerosane to delute your WMO since we have this thing called winter up here?
