hello all.... what a great site. i have read some but not really sure what to use so i need a pro's help, my question is this. i looked for the amsoil but to no avail someone told me sta-bul for diesel was better than anything. because i am new to the tractor thing i was just wondering what to use. i have the bx25 and i also have the summer mixture from my local station ultra low sulfer. any help thanks.
