Who knows anything about Bio-Diesel???

n/a

We have a local supplier for Bio-Diesel and it's quite a bit cheaper than real Diesel. Is this stuff bad to use in a Cummings Engine? How does the gas mileage compare to the real stuff. I know nothing about it, other than it's made from soy beans. Thanks!

Us it! A little bit weaker up hill but just as good otherwise.

Lower sulfur and soot, and better lubricity than regular #1 and #2 diesel. I haven't seen it come in cheaper anywhere yet around here. Milage should be the same to slightly better. As long as the fuel meets the same spec as what you usually run, you should be fine. If it were offered in blends with a high proportion of bio in the blend, like an 80 bio/20 dino, you might see some extended oil life from it, but I doubt that you'll see a change in a 80 dino/20 bio blend.

there is a guy at work that makes his own out of restraunt cooking oil he said it works great

Lazerus...have you used this stuff. I'm seriously thinking about ordering some. Thanks!

I thought that you had to make some slight changes to the engine to run this stuff. Diesels are sensitive to impurites in the fuel. Would it not plug up the filter?

They had a TV sevies about a guy that does the conversion for the Jetta TDI to run on this stuff. He talked about some modifications that had to be made.

Cooking oils are not all soy based, you can get many different types of oil, I'm sure you know this. I would think you would have to run this oil through a filtering process several times to get the chicken wings and hot peppers out of the fuel.

Use in all our trucks. Works great.

Eric... do some research at this website - http://www.biodiesel.org/

If I could get Bio-Diesel locally, I would run nothing but it, and would not buy regular petro diesel... and I own a Cummins powered Dodge Ram. Bio-Diesel does not require a different fuel filter, and it is not made from regular cooking oil. It is made from soybeans.

As for the person who said "it is a bit weaker up hill...", he does not have his facts straight. Bio-Diesel has a higher cetane level and it produces more power per pound of fuel than regular petro diesel.

There is no way on earth I would ever use diesel fuel make from used cooking oil. The first issue with it, is that it will void your engine warranty. True Bio-Diesel will not void your warranty, and it is enorsed by all of the diesel engine manufacturers. The other issue with "home-made" diesel is that it is not clean, and it will clog your fuel filter.

Again, check out the website above, and then make your decision.

Keep in mind that all the websites talking about biodiesel are pro-that topic so the "facts" might be a little skewed. If you use it, just don't think you are doing the environment or the oil supply any bid favors. Our city busses run on the stuff and we did a study. It turns out that it takes more fuel to create the stuff than you get from it. Think about it when you see a farmer plowing, harrowing, harvesting, trucking, etc.

Have used a 15 % blend....power & milage both suffer alittle. This was in a semi-truck.[:)]

It is very important to understand that so called soy-diesel and bio-diesel are two different fuels, even if both contain soy bean oils. Running unesterized soy bean oils, animal oils or other types of plant oils in a diesel engine is going to lead to fouled injectors and worn internal engine parts, due mostly to the glycerin present in such oils and will no doubt void your warranty. Burning bio-diesel (also known as soy-diesel in some regions if processed from soybean oil) is an accepted practice that is consistent with most engine warranty agreements. Bio-diesel is an esterfied vegetable or animal oil that can blended with petroleum based diesel fuel. The steps to make bio-diesel from soybean oil (called transesterification) involves adding alcohol to the soy bean oil along with a catalyst and mixing it all together. The ester (the bio-diesel) will rise to the top and glycerol, along with the alcohol, will settle on the bottom and after several washings the bio-diesel can then go into your tank.

My fuel supplier now only handles 5% soydiesel road and ag and sells it for same price as everybody else is selling 100% dino stuff for.. I burn a lot of it and have no problems... i noticed improved mpg on my powerstoke by about 2 mpg and power is a little better also

Thanks "Kristov" and others for the information in the above posts. I did not understand the different kinds of so called Bio-diesel fuels available. There is used cooking oils, soy based oils, and true refined Bio-diesel. I have a better understanding now.

The bio-diesel website claims a 3.24 times energy recovery. Thats over 3 times the fuel used to produce that bio-diesel! If thats true its a much better source of energy than the ethanol idea.

What is the cost per gallon of the various blends of actual Bio-diesel? They talk about a 5%, 20& and 100% blends.

The home cooking oil blend looks to be very a very cheap per gallon cost once all the modifications to the car/truck are made and the filtering system is set up in your home or at the source.
