I didnt have to do anything to run biodiesel...... except change my filters As far as I know it would be the same with any older diesel engine... mine is a 6v82t though...... It's just the svo (straight veggie oil) that rots steel and stuff over time that get into the injectors, or hardens up in cold. The biodiesel is svo that has been chemically altered to be very much like the old diesel that our engines were actually designed for

So far as bio diesel just pour it in and carry extra filters with you.  Bio diesel is derived mostly of used vegetable oil.  The end product acts as a solvent and will clean every piece of nasty out of the old tank and send it straight to the filters.  Thus you need to carry extra until the old stuff is gone.  Then replace filters as normal from then on.  Welcome to the movement!!!!!

they are not really making money!!!

right now you can sell just WVO for $ 3.60 per gallon to the large recycling companies.
so if you ad the cost for methanol and to process and wash it, there is no money earned.

the price for used oil went up like crazy in the last weeks, and if you dont use wvo straight, it almost makes no sense to do the work for bio diesel. the price change is also the reason that the oil war (how i call it under us collectors) is getting harder, and recycling companies or wannabes are showing up from everywhere to make some fast bucks.

These guys paying $3.60 a gallon for WVO must not be using it for fuel.  By the time you pay to haul the WVO and your overhead you're at close to $4 a gallon before processing the WVO for fuel use.

I can buy dino diesel For $4 a gallon here in Minnesota today.

If you include all the parts you have to buy to make Bio Diesel and your labor time (use $50.00/hour), and the fact that WVO will muck up the engine, it's just not worth it.  Now if we had to burn it because dino fuel wasn't available-that would be another story.  Good Luck, TomC

Ive heard of people making furniture polish out of it..... $3.60 a gallon?! $16.00 a gallon? Oh my!!!

edit: This must be a regional thing...... my brother in Idaho says he is still getting his oil for free. Of course, here in Cally, it is impossible unless you know someone and then it's illegal unless you pay fees and have $1 million insurance, a sign, the right zoning, etc., etc., etc.

Alright TomC  can you explain this "Fact that WVO will muck up your engine"?  I never knew this to be a fact.  What does muck up your engine and where are you getting that information from? 

And I'll be glad when I make $50 an hour.

I cant see how anyone could justify running it.  With the time and effort you have to put in to acquire the stuff, extra filtration, cold weather issues, etc.  I think it would be cheaper to just run dino diesel.

I've seen plenty of pictures of the residue from WVO making deposits on the engine, and the slobber goofing up the valves that within 100,000 miles have to take the engine apart to clean it and possibly do a valve job.

Most people that are self employed are making at least $50.00/hr.  When I was driving, is making an average of $1.10/mile (back in the 1990's when fuel was down below $1.50/gal).  Averaging 60mph that would put me at making $66.00/hr.  Most plumbers make around $90.00/hr.  What does your auto shop charge?  I know our truck shop charges $110.00/hr.  Believe me, if you were in business for yourself, anything less then $50.00/hr wouldn't be worth the time.  As an employee, that's a different story since you don't have the risk of being in business for yourself.  Good Luck, TomC
