My son is a vegetable

Note the filters and stuff it runs great and no more fuel costs. We have a Co-op with a neighbor and we collect vegetable oil from the Chinese resturant twice a week and he filters it. 25 mpg and its all free baby, no pollution.

A camping buddy of mine does the same. Mercedes Diesel plus a duece and a half. The Duece is his camping vehicle. He picks up grease all over town. He saves the restaurants money and saves himself money. Seems like a good all around................

Matt, do you add ethanol to the mix or just add it to the diesel in the tank. Try doing that over here and the Govt. wants 47c a litre (about $1.80/gal) as you are deemed to be a producer and they need their tax.

Paul,
You guys need a talk with your government. You are saving the environment twice, they should pay you.

Does it smell like french fries when you follow it? I know waste oil burners do when you use that stuff!!

We just had a diesel fuel change about 2 months ago which makes the fuel very "dry" as far as lubrication goes. The West coast has had it for over a year and now it is standard throughout the country. The sulfur content is now at or below 15 parts per million and is called ULSD15. What makes it so dry is the process by which the sulfur is extracted. Hydrgen gas is bubbled through the diesel until the sulfur content is down to the standards. The hydrogen not only takes the sulfur out but takes the lubrication out also. The higher the sulfur content in the crude the more treatment it needs = drier fuel. Fuel system engineers design the injection system for a minimum lubrication content to make the parts last. They leave the guy pumping the nozzle in the tank to make sure that there is enough lubricity in the fuel. There is no government standard for lubrication........... yet.

Be careful using old cooking oil for fuel. If animal meat is cooked in it, the acids can cause damage to aluminum parts of the injection pump. It may eat up the savings in fuel to repair the injection pump. Adding ethanol to diesel will only make things worse. To me, using Biodiesel is the way to go. I've seen problems with running 100% soy oil but the only problem with a 15%-20% blend is some filter clogging issues because it seems to knock off some crud buildup out of the tank for awhile. Kind of like a decongestant for us.

We are running 100% soy, our neighbor has been going for 8 months with no problems, the guy who installed it said we would be degunking the lines for about three tank fulls, We are very excited about this. even if we can't find used oil, 5 gallons at costco is cheaper than deisel and yes it smells like a chinese resturant.

Matt, I think it's fantastic!! I have been wanting to get a diesel vehicle to run biodiesel in it, but it seems that since they put the new fuel standard in place (which isn't a bad thing) the vehicle manufacturers have pulled a lot of their diesels until they can put in an engine that can deal with the new fuel. I had been looking at the Jeep Liberty diesel and the Passat TDI stationwagen, but now neither of them is available for 2007. It looks like Jeep is going to offer the Grand Cherokee with the Mercedes Bluetec diesel engine in 2007, but that one is a bit out of my price range. Looks like I'll be waiting a while for more diesels to hit the market again. As for the lubricity issue with the new fuel, there is a really easy solution....add at least 5% biodiesel to the mix. Better yet....use 100% biodiesel. Now if only the vehicle manufacturers would cover that under their warranties.

I would really like to see a compact diesel pickup.

Here's a NYTimes articlethat runs through the mechanics of how grease cars work, it mentions that there is a $2750 fine for violating the Clean Air Act.

Not that they are going to nab you though.

There's a companion article about why it's illegal
