MYTHBUSTERS BUMP.

OTOH, they did confirm on the same program that filtered, used cooling oil can be used directly (without having to refine/distill in a reactor) in a diesel car - looks like an older Merz. 300 Diesel was used. I wonder if that's REALLY true. If so, I could be riding around for a lot cheaper on my TDI than I am now.

Absoloutely that is true. Diesel engines were originally designed to run on peanut oil. If I owned a diesel, I would be hunting up a buddy who owned a fish camp or something similar, and get myself a source for used grease. I would then make myself a filtering station that could pretty much be left up to gravity to handle the job. As a matter of fact, I'm leaving right now to go buy myself a diesel!

I actually saw a guy doing this 2 weeks ago. He goes around to all local restaurants who normally pay to get rid of the stuff and takes it off their hands for nothing. He puts it in barrels and told me that he uses it in his truck. He said he had to have conventional diesel to start the truck, and after it was started he could switch over to the home made fuel for driving it. Seems like a clever idea. It isn't a solution though because if everyone did that there wouldn't be enough of a supply of such oil because everyone and their brother would be looking for it.

Its true, I have a buddy burning used cooking oil in his ford pick-up truck.

Yes it is really true. I have a friend with a Dodge pickup that has a cummings diesel that runs on used cooking oil. You have to start it with diesel. When his truck warms up he switches to the cooking oil then switches back when he shuts it down.

Going to work one morning I began to smell intense french fries. Then I noticed a sticker in the window of the Merc 300D in front of me claiming it ran on cooking oil. I absolutely believe it. And it stinks to high heaven! If more cars ran on that stuff I could not leave the house without gagging. It was that bad!

As others have pointed out it does work. The only downside, well, other than your exhaust smelling like Taco Bell, is that if you live in a cold winter climate you'll probably have to switch back to diesel during winter as it's apparently a bear to start on cooking oil in cold weather.

Plus once this catches on used cooking oil won't be free and it might end up being the same price as diesel.
