i have a bunch of biostations around here and i would love to take advantage of them but i dont want to put it in my truck if i gonna screw it up so my question is what blends can i put in my 95 with 225xxx miles, however i was told that i need to upgrade my fuel hoses, is this true as well?

 

You do need to upgrade your fuel lines. Ford started using the "bio friendly" fuel lines in 97.

 

Ditton on the fuel line upgrades.

But beyond that, the 7.3 is a super friendly engine for a lot of different blends, including straight VO.

Those big, low pressure injectors will spray some pretty thick stuff that would clog the 6.0's.
