OK all, I have six diesel trucks running for my work crew plus eight gas trucks. I am contemplating looking into making bio diesel and running it in the trucks. Is it more hassle than its worth? I know there are a multitude of sites with info on bio fuels. I guess I am just looking to see if any of you guys have gone through the trials and tribulations so I can make an educated decision. the used wvo is not scarce to me either. SO let me know what you all think
