but OP noted this is about multi-fuel old engines. All those 2400 new truck engines better be able to run perfect on the new mandated fuel as they are mandated engines controls and design. OK back to the old engines.
To clarify.. I think with all agree with you about crap fuel both gas and diesel, so you dont need to keep saying "there I said it". Second I was referring to someone who had an issue with a new dura max destroying its injectors. I am positive it did just what he said, however..We used to have around 100 dura-maxs, mostly in C5500's.. We did put some injectors in but none that I can rememeber destroyed a whole set. 3rd, all our fleet is not new. By new i meant not as old as our multi fueled engines. Some are 20 years old, but of course none as old as my 1971 M35

I do have a question, So you run new motor oil, at around what $8-11 per gallon at best, mixed with 50% fuel??? That some pricey fuel your using unless you get the "new" oil for free.
