Ok, I got legit plans from guy I know who makes fuel from waste veggie oil. He runs it in a 2001 Ford Excursion with a 7.3 and it runs good, he's got 40,000 miles on it with the veggie oil. I tried to make it with his same plans, but it didnt run so good in my truck, which is an 86' F-250 with a turbo 6.9L. Here is how I make it...I get oil from a local resteraunt, that I work at, about 40 gallon a week, I have a filter setup in my garage that i run it through next. It is 2 pumps that forces the oil through a 20 micron hydrolic filter then a 5 micron carbon filter, I filter the oil twice. The mix calls for 10% Kerosene and 5% gasoline and a certain amount of 2 different additives. Now I ran this same mix in my truck for about 500 miles, now it wont run on it. I understand that my truck is older and has less fuel heaters and such, but I think if I double the amount of the ingredients it calls for each batch, and filter it more, I can run it succesfully. What do you guys think, try that, or actually make bio-diesel with the methanol and the lye?

 

Make BioDiesel

 

replace your filters and then make biodiesel

 

Make Biodiesel!

 

If you don't want to make Biodiesel you need to convert to a heated WVO system. It will cost you between $1000 if you do it your self or $4000 if you have some one make and install it for you.

WVO works if done right..... If you do it wrong in about 500 hrs of running you will need a new motor.

Or you can do what some very smart people have already said and make Biodiesel.
