The injection system on my 03 6.0 liter is more critical of these fuels than the earlier 7.3s. They are higher pressure and therefor have to use cleaner fuel. My Vegistroke system heats the WVO to above 160 degrees f, bringing the viscosity to very near the same as diesel fuel. Boi-D will give you viscosity issues in the winter time if you travel north where it is cold so don't attempt to use it in January if you travel to cold country!
Youll love the bullet proof 7.3 PSD! A very good powerplant!
