I converted my e-350 van to run on waste oil. Its been running on it for about two months. I filter the oil just to get the chunks out. The van is getting between 16 to 20 mpg's running on the oil at 55-60 mph. The van was a tired work horse when I bought it, it smokes some and has a engine tick that increased as rpm's rise. This was before the oil conversion. The van seems to eat the oil with ease. When I change to the oil tank from the diesel tank it feels and sounds seamless. Anyway if you'all have any questions feel free to ask. It is a great feeling to be running down the road nearly free. Driving has become my recreation. Windsurfing, camping and going places are done without the big fuel bill at the end of the trip. Take care, Dan

 

What was done to convert the van? Are you running pure waste motor oil, or mixed with diesel? How many miles do you have on WMO? I want to run mine on WMO, but am a little scared of what it might do to the fuel system or engine. What do you do to clean the motor oil?
Thanks for any info!

 

To 88 E-350. I built what I call a "Hotbox" and welded it to the bottom of the rear fuel tank. The "Hotbox" heats the 100% used restaurant oil. The "Hotbox has two 12 volt water heater elements and a heat sensor built into it. The cost to build the "Hotbox" was aprox 120$, it has already paid for itself. I did it myself. If you want to see detailded pics and a log of the build you can go to (mypowerblock.com), in (search) type in (waste oil). This is not spam. I made this log to help other folks learn how to use restaurant oil in there diesel and save money. Check it out and tell me what you think 88 E-350, Dan. P.S. I have not used waste motor oil just used restaurant oil. Thanks for your post.

 

Pretty cool. If you're still having leakage issues and welding is proving tough, just epoxy it. I would clean it completely and run some JB weld over the entire weld area, it'll surely stop the leaks. Can you give me a basic rundown of what your filtering process is? Thanks.

 

Good idea with the epoxy and JB weld. The leaks are now just weaps with no dripping so I just wipe it down every now and then. My filtering process is very simple. I buy some material at the local as is store. Not cotton, like ladies hose or something that things don't stick to. I put chicken wire over a open 10 gallon bucket to support the material and then start pouring. If I see the white stuff or other junk that usually accumulates at the bottom of the waste oil containers then I stop. It comes out looking like maple syrup. Its all very low tech but saves so much in fuel cost. Take care, Dan.
