ULSD is already being used in Kalifornia and parts of Texas. Its not really a threat to oil lubed IP's like the MB's have, more of a problem for fuel lubed rotary style IP's like in older VW's, GM's, Fords, etc. Even this is not a big deal as it is simple to add a lubricity additive at every fillup even if its just a little motor oil. Sorta like the additives to keep unleaded fuel from causing valve resession on old gassers. As IP's are rebuilt the new ULSD compatible parts are used and slowly the issue will go away. RT
