Waste Vegetable Oil for my Diesel Truck?

Question

Hi all, thanks for helping me with my question. I have a 1984 Chevy C-10 pickup with a 6.2L diesel. It gets 21 mpg on diesel. But at $4.50 per gallon, I need a little help to get it to burn WVO. It has two tanks so I figure that I can just filter the WVO a couple of times and put it in the tank. I will start it on diesel and shut it off on diesel and burn WVO in between. Any suggestions?

At least use fattywagons.com injection line heaters.

Answer 2

You'll have to install a heating element in the fuel tank taking the grease (which is what it is). I've seen conversions before that used copper pipe that was tied into the vehicle's cooling system to warm up the tank to liquefy the grease. You'll also have to change out all of the rubber hoses to stainless or copper/brass or they'll dissolve.

Answer 3

Filter the used vegetable oil down to 5 microns (you can get filter bags on ebay). Add 10% kerosene and 5% unleaded fuel to the oil and mix it together. This will thin out the vegetable oil to run great in your truck. I've used it for 3,000 miles so far in 99 vw jetta tdi.

Answer 4

Sounds like a good plan. Most diesel engines will actually burn lube oil.
