Posted Aug. 4, 2007 and written by Michael Pike himself: "The Veggie Voyager, an ’87 Ford F-250 four wheel drive ¾ ton pickup with
an 8’ cabover camper, is a multifuel vehicle, able to run on diesel
fuel, bio-diesel, or straight vegetable oil (SVO). Our fuel mileage
varies from 12-15mpg.
Diesel fuel has been cleaned up considerably in
the past year with the removal of most of the sulfur, but is still a
dirty fossil fuel when used in older vehicles like ours, so we only use
it for the first few miles while waiting for the SVO to warm up enough
Bio-d and SVO are both derived from vegetable oil, but Bio-d
requires a complex chemical process using methanol and lye to strip off
the sticky triglyceride part of the oil molecule. It would be difficult
to do while on the road.
SVO only needs to be cleaned or filtered
and have any water removed. In order to burn it as fuel we have to heat
it up to ideally 150-170 degrees F.
To heat up our veggie oil we have
a heater hose from the engine that heats up an oil pick up tube in our
veggie tank, then goes to a heated filter and finally to a small heat
exchanger box. The veggie line is sandwiched between the heater hoses,
so it gets warmed all the way to the fuel injector. A temperature gauge
tells me if its hot enough to burn. If its not, there is an electric
heater that kicks in.
There is no obvious difference in engine
performance when running on veggie. We do lose the nauseating diesel
smell, the black soot on hard acceleration, and we have the good feeling
of not burning fossil fuel. The gas mileage, unfortunately, is about
After years of using an Acme juicer centrifuge (seen in the first photo) Michael bought himself a "treat." It is a WVO Raw Power Centrifuge... this enables him to increase waste grease conversion to clean combustible veggie oil from 8 gallons per hour to up to 25 gallons per hour.
I just wanted to post this first veggie processing with the new centrifuge... so clean! His smile... so big! And, note... this monster centrifuge is made in America... Win, Win, Win!
