Welcome to the forum! Lot's of people seem to be using veg-oil conversion kits or run WMO. I run biodiesel myself and have made about 1500 gallons so far without much issue. Running bio you just pour in the tank & go, no separate fuel system or any of that stuff. Only issues: cleans the crap out of your fuel system / keep extra filters. slight loss of power / I only really notice towing the boat up steep hills. Lose about 1 or 2 mpg on the highway, but at less than $1.25 a gallon, I'll deal with it... It also smells funny and runs quieter...
