Bio Diesel

[Okie4570]

Filtered with dry fiber wound filters, like for water filtering. The warmer the oil, the faster it would pump. Pump was a $70 pump from Harbor Freight. Did all of this back when diesel was way over $4. As the price of diesel came back down, I lost motivation. A couple of guys I knew that were really in to it, and one guy still is I think, bought centrifuges and spun the solids and waste out of the WVO.

Anybody done it on 6.4L?

We were looking into it for the tractor back when diesel was over $4, but have let it go by the wayside. Spring plowing coming, getting a bit more interested again and thinking about putting it in the F350, too.

I can't answer about the 6.4. However, my buddy has found it tougher to get waste vegetable oil as of late. The restaurants must have somebody picking that oil up for free or are getting paid for it. I believe they used to have to pay for disposal, so if they could get rid of it free, they were glad to have somebody back up with 55 gallon barrels and a pump.

I have not been able to do this as I do not have a diesel vehicle or the space but have looked quite a bit up.

When you process WVO and run it mixed you should be highly filtering as well as have a heater on a storage tank to help remove excess water from the oil.

Making true bio diesel requires a setup to heat the oil after filtering do the mixing in etc., methanol, sodium hydroxide or potassium hydroxide (lye) and WVO. When you are done processing you have to separate the glycerine remove the excess methanol and then remove the soaps that form in the diesel. Removing the soap is oddly enough done with a simple water wash system in small setups and large companies use a centrifuge to separate, you can also buy a filter but they generally don't last a long time and will increase the cost of making. It is a multi step process but helps to ensure better compatibility with newer engines.

And for all the extra info http://en.wikipedia.org/wiki/Biodiesel


True biodiesel is a much better solvent than regular diesel so generally you have to change the rubber lines to synthetic as the rubber will slowly be dissolved and either leak or break apart causing debris to get into the pumps/injectors. If you want to watch the dirty jobs episode you can do so here http://www.youtube.com/watch?v=sEl0I0-kZW8 or look up Season two episode five on Netflix of Dirty Jobs http://en.wikipedia.org/wiki/List_of_Dirty_Jobs_episodes#Season_2_.282005.E2.80.9307.29

The restaurants do get paid for it ( pretty well too )

Years back, they paid for disposal and it wasn't cheap.
Was pretty easy to get the oil for free, as long as you were prompt on pickup and removal. some generate a lot a oil and have limited storage space. As the bio and WVO craze grew, more and more were asking for it for free and the trend has slowly turned to having to buy it. We have a source and have looked into it considerably, but remain hesitant about 'playing' with the fuel systems on a $$$$$$ vehicle.

Really like the concept, know enough about the chemistry involved for true bio, but leaning more to the WVO and diesel mix. (just my random thoughts)

It's not good for any of the new fuel systems. True bio diesel is a different story but you can't run it straight.

I have no clue if the info in this link is worth a hoot but here it is anyway :-)

I have a friend that uses straight used transmission fluid in an older non turbo Ford.
Drove many thousand miles without any issues..says the turbo Ford will not work with it like that.
He works at a Ford dealer. Not that it makes any difference.

Want to keep bugs from eating your pine fence and keep it from rotting..Paint it with used transmission fluid and a paint roller.
Get the runners also as the ants want to nest behind the 2x4's
I put one up 14 years ago and it looks great...paint every 3 years or so.
I built that fence from used dry pine from large pallets.

Have a wonderful cold day.
