I'm wondering about how much it would cost and what conversions I would need to make to run it in a 99 7.3l SD. Is it even worth the money??
Are you going to brew your own or buy it retail? If the later, it all depends on how you look at it. When I can find it...and it's not 50 cents more a gallon...I burn B20 through my '04; that's 20% less foreign oil that I'm burning. Someday I'd like to homebrew...but it's not a safe option for me right now. As far if your truck will burn it...or be ok. It will burn it all day & night long. The only problem you might have is when the biodiesel cleans your fuel lines out. You might clog a couple of filters at first, but after that...all will be well. That, and cold weather gelling...depending on where you live.
