Anybody know anything about Dee-Zol diesel fuel treatment from Bell Additives in Florida? I talked to a couple people today that have been using it for years and swear it's the best thing ever made. One guy, who is a high performance diesel sled puller/mechanic, has over 400,000 miles on a 5.9 Cummins and has never missed adding this stuff to a tank (he's also never used anything but Schaeffer Oil.) He tore the engine down thinking it was time for an overhaul and it looked brand new. Just curious is this was a fluke or if Dee-Zol is the real deal? Or, could the oil be doing more for the engine than the fuel additive?
