Anybody have an informed answer as to why diesel is is more costly than gas lately ? far as I know it requires less refineing Is in lower demand, at least in the U.S. Is it the new low sulfur requirements ? temporary refinery problems or what ? Im in Ohio and it is up to about 2.50/gal right now. It was historicaly cheaper than gas but not for the last year or two. Getting a little expensive to feed the old 7.3 lately. Not to mention the tractor.
