[VAL] Dinosaur vs Bio vs Veggie oil fuels...

["Mark" <mark@xxxxxxxxxxxxx>]

Patti,

Bio-diesel is a refined and doctored product, which is interchangeable with
dino-diesel in many diesel engines.  Veggie oil (or used cooking oil) will run
a diesel engine just fine BUT, it's too thick to work without pre-heating.
All it needs to work, in addition to heating, is careful filtering to remove
the left over food particles, which could easily clog tiny holes in the
injectors.

Veggie diesel conversions require engine coolant lines Siamesed to the fuel
lines, all the way back to the required second fuel tank , which also has
heating coils to warm the veggie oil inside, in order to get it thin enough to
flow through the pump and injectors.

With veggie oil systems, one starts the engine on dino-diesel then, once the
veggie is hot enough to flow, you flip a switch which shuts off the dinosaur
juice, and turns on the veggie oil at the same time.  You also have to switch
back to dino for a few minutes before shut down, to purge the peanut from the
precious parts, so it won't thicken and clog up everything important.

Veggie conversions aren't practical for running down to the Quick Stop on the
corner for a six-pack, but for those who will be on the road all day long, you
just can't beat it, except for the mess and time involved to filter the
stuff.

The diesel engine was originally designed to run on vegetable oil, but the
petroleum industry decided to refine crude into diesel for the added
convenience of not having to worry about having to heat it to thin it out.
Many operators claim their diesel engines run better, and give better mpg, on
veggie, rather than dinosaur, diesel.

And, of course, the exhaust will smell like whatever was cooked in it.  If
your used cooking oil source is a fish'n'chips place, you might have to worry
about being chased by cats, instead of dogs...

Did that help?
