Have you converted your car's engine to use waste vegetable oil from restaurants?

In the UK you’re still obliged to pay the fuel duty which is most if the price over here. Also I thought if the car had a diseal engine it didn’t need converting to run on vegtable oil?

You should check out this blog posting about the Gaza Strip. Forgetting the politics for a moment, it makes you wonder whether you want your car smelling of french fries, all the time.

I wish I could, but the conversion assumes you already have a diesel engine car, which I, unfortunately, do not. Otherwise I’d do it in a heartbeat.

No I’m not green, I’m white.

My friend does that. He’s got an older mercedes sedan (obviously it’s diesel).

He gets all his grease for free from McDonald’s and then purifies it in his back yard.

Susanc mentioned, a long time ago, that she had a car that ran on grease for a while. The aroma was that of McDonald’s. I will never be able to find the question.

I thought about it for awhile but I don’t have a car :/
@ LightlySeared, you have to do it with a diesel engine , it can’t really be done with a normal gas engine because of the way they work. The diesel stills needs small modifications because grease solidifies in cold temperatures (i.e. winter) so you have to preheat it, and other things.

@seVen In your avatar picture you look green to me…...hmmmm

no I get good gas mileage in my manual Honda

I wouldn’t under any conditions convert my beemer to smell like McDonalds…..that stinks!!

In my state, to do such a thing is illegal. So no, I haven’t tried nor am I likely to give it a go. Although, historically, the original diesel engine was created to run on cooking type oils.

To all: Dont even think about putting spent cooking oil in a modern Diesel engine.

It sounds good initially. But In the long run, the supply vs demand becomes a problem. Right now most restaurants are thrilled to have somebody haul the stuff away. But if an interest developed, they might start selling to highest bidder. I may be biased though, I live in ethanol country-the Midwest.
