I know Ford says no more than 5% Biomass in fuel used in the 7.3. Then they recommend replacing filters sooner if you do use the bio fuel. Well, here in Illinois you can hardly find a station not selling B-20 Bio Fuel, and my 7.3 does not like that stuff. Runs like crap, no power and poor mileage. So, my question is, Anyone know how to convert a 7.3 to except B-20 like the new 6.7's that are B-20 ready?

Thanks for reading.:bowfast:

Put it in your tank and run it...

I've run B5, B20, B99 and B100... No changes what so ever.

The B99 for a few months caused me no end to issues because it ate the fuel lines I used in my fuel system.

I noticed slightly less mileage, but a much quieter running motor.

Been running B20 pretty frequently in our 6.0 & 7.3, the 6.0 definitely likes the stuff & the 7.3 is quieter, seems a bit friskier but could be my imagination. So far no probs.... yet?

you should be fine with the B-20, it just sucks if your towing on it, less power and worse mpg's
