“ . . there were people complaining about gas prices. I think we should talk about ways around it. I think Bio diesel Is the way to go.
Reason 1: We pay between 2.80 and 3.20 a gallon
Reason 3: Bio diesel is fairly cheap and can be bought in most states.
Reason 4: You can actually make this stuff yourself.
Reason 6: The materials that are used to make this can be found in most restaurants, auto parts stores, and kitchens.
Reason 7: Best of all The price for making this Bio diesel is around 50 cents to 1 buck a gallon. Materials for Bio diesel - Cooking oil, Methanol, and Lye.
People who have Bio diesel exp step up and help spread on how cool this is.
From what I understand you can use any diesel engine all you have to do in some cases is convert the carburetor. Lets hear you about this . . In a good way.

I know a friend in the bio-diesel business. The process can be done at home - but less hassle if you buy it from a business.
Basically:
1. The company sells vegetable oil to a company - it is recollected by the sales company for nothing.
2. It is then taken back and refined to make is fuel worthy
The only side effect of the process is your car will smell like anything the restaurant has been cooking
AND
I have heard several reports of diesel engines failing for some unknown reason when using bio diesel.
It is basically a win win business. You sell to the company, collect their waste for free and then sell the 'waste' on for extra profit. [Edited by Don W]

Or better yet, brew your own and drive for about $1.00 a gallon.
I've been running B100 for quite some time, and I dread having to go somewhere where I'm not at least a B20 blend.

But you said 2 or 3 things that I want to re-visit or re-emphasize. 1) The “refining” process for turning used cooking oil into combustible bio-diesel fuel is nothing more complicated than running it through a fine filter to remove the injector blocking solids.
I expect poor filtering is the root cause of the engine failures you mentioned. You cannot “play” with the injector system of a modern diesel. If you reduce the amount of fuel spayed into a cylinder but keep the engine running, you will raise the heat level in that cylinder to piston burring amounts - and quick!
2) Every restaurant produces fair quantities of used cooking oil. For many years the used oil has been collected by a few companies. It was then filtered and re-packaged and sold in Mexico and other (poor) countries where used cooking oil is not a cultural no-no as it is here. It would be a simple matter to divert this into bio-diesel to sell at the pump.
If you can find the number of gallons of cooking oil used by US restaurants, I think you will find the amount is too small to make this a useful alternative source of fuel for motor vehicles.

“ . . the process of cooking oil into biodiesel is more complex than simple filtering. There is actually a conversion process (transesterification) where the the hydrocarbon chains are broken, and subsequent bonding with the methanol. [Edited by Don W]
Particulate matter in fuel won't be an issue with biodiesel, Any diesel engine will have from good to excellent fuel filtration depending on manufacturer. Finally, too little fuel won't hurt pistons in a diesel, unless you causing thermal shock, and crack a piston... No fuel... No EGT... Burnt pistons are always a result of too much fuel.
[biodiesel] is already a viable alternative energy source, and only a small percentage of used cooking oil is being reclaimed, on top of that, there's virgin biodiesel that is being commercially refined across the country.

There was a post you made a while ago to show how cool Biodiesel was compared to a gas engine.
You shows 3 links of a truck blowing the crap out of a 68 camaro and a few others cars in a drag race. Can you slap them links here for I didn't save them I just looked thru the post I believe.

That guy is running #2. The reason I posted those videos, the information regarding the Audi TDI LeMans and Sebring victories is to lay to rest the common misconception about diesels and performance. Nothing produces torque like a diesel. [Edited by Don W]

Q1. Was that a 1/8th mile drag strip?
Q2. In the first two videos, did the truck get a head start?
Q3. What engine class was the gasoline car in Video #3?

Buddy on there demo'd making a batch of the biodiesel with the equipment that can be picked up from sites like this: www.homebiodieselkits.com... and then put it into that truck..... Lets just say, it got rid of the treads reall fast

“ . . after high performance modifications, alternative fuels was next on the hierarchy of discussion . . the BTU rating of vegetable oil is too low compared to #2, or even B100 (BTU's means horsepower) in my constant quest of vehicular power-age. [Well] maintained diesel engines can easily hit the million mile mark. Biodiesel is definitely the way to go. [Edited by Don W]

The Cummins 329 hp N series engine is an in-line 6, displacing 14 lifters, or 850 cubic inches. I have looked on Google to find the weight of this engine but no where is it to be found. My guess would be well over 2,000 lbs. A Dodge pickup called the Sidewinder was clocked at 222 mph which may be using the new Cummins 610 version. I would guess the 610 would weigh in at 900-1100 pounds. The extra weight in diesels is used to strengthen the block, especially the lower end, the crankshaft, con rods, pistons and head. All due to the very high compression ratios for compression ignition engines. Customers use these engines to the max day in, day out. At 50 mph for the allowed 10 hours a day, the truck can easily run 3000 miles a week, and who knows how many more if the driver has two or three log books?

"There is just no energy benefit to using plant biomass for liquid fuel," says David Pimentel, professor of ecology and agriculture at Cornell. "These strategies are not sustainable."
In terms of energy output compared with energy input for ethanol production, the study found that:
A) corn requires 29 percent more fossil energy than the fuel produced;
B) switch grass requires 45 percent more fossil energy than the fuel produced; and
C) wood biomass requires 57 percent more fossil energy than the fuel produced.
In terms of energy output compared with the energy input for biodiesel production, the study found that:
A) soybean plants requires 27 percent more fossil energy than the fuel produced, and
B) sunflower plants requires 118 percent more fossil energy than the fuel produced.
Prof. Pimentel advocates the use of burning biomass to produce thermal energy to heat homes, for example; he deplores the use of biomass for liquid fuel. "The government spends more than $3 billion a year to subsidize ethanol production." Ethanol production in the United States does not benefit the nation's energy security, its agriculture, economy or the environment," said Pimentel. "Ethanol production requires large fossil energy input, and therefore, it is contributing to oil and natural gas imports and U.S. deficits." The report is in “Natural Resources Research” Vol. 14:1; p. 65-76.
