Can you make your own fuel? Biodiesel?

Lard isn't worth messing with.

If you get a good supply of WVO and plan to use it as a percentage istead of making bio, be sure to test it to titrates. If the WVO is too acidic, you may want to pass on it.

 

Tolerances are so tight in the newer fuel systems that the repair alone of biofuel will by far put you in the hole. Even cleaned and dewatered it just won't cut it in 99 percent of common rail tier III and IV fuel systems. Call a diesel injection repair shop that does pumps and injectors and ask what their most common failure cause is contaminated fuel will be the answer. My old B model would probably get along ok with it but I wouldn't chance it. I can buy biodiesel right at the future fuels plant 30 miles from home, 60 cents a gallon cheaper. Lots of us used to we all learned a lesson. If it can't be done in a multimillion dollar facility it can't be done in your garage either. Cost 6 injectors on our C16 we got off light. I gave several guys a bill for 5 to 6 grand needless to say there is never a line at future fuels anymore.

 

You do mean titrate a sample to know what the acid level is so you can adjust the lye solution?

 

I understand your question and I thought I answered it but this is a good discussion about the opinions of using WO. To me it isn't simple enough to just use it straight in a truck or everyone would do it. At one time I processed it for my own use, it was easy to get and process. This was before it was a fad with ready made processors or "kits" from these pop up companies or long before those grease car people even heard of it. Now it is nearly impossible to get the waste to process it so I just went back to dino fuel and sold off all my stuff. Even now there are issues with waste oil recyclers threatening places if they give it away and so on.
