Hey guys, thanks for the responses.

So what will it take $$ wise to realistically get going with this?? I have a free source for veg oil, my brother owns a restaurant and says its all mine if I want it. Also he uses canola oil mostly due to all of the hub-bub over trans-fats, will that make a difference?

What is the breakdown? as in how many gallons of cooking oil makes how amny gallons of fuel??

Do most of you guys run two tanks like willbd? How and who or where could I get another tank installed? sounds like to big a job for me!!

And I guess what I really need to know is if it's worth all of the time and effort?? I have people telling me thats its not worth it and it messes up your engine and voids any warrenty.

thanks in advance for the info guys.
