what are the differencese between a biodiesel engine and a petrol diesel engine. what are the importants of using a biodiesel engine compared to petrol diesel engine. what are the benefits if using a biodiesel engine.

We drive an 06 VW Jetta TDI an 99 Ford F250 w/Powerstroke diesel. We brew about 75% of the fuel we use from used restaurant oil. Americans collectively spend 0,000 a minute to buy foreign oil. It is great to reduce our personal petrodiesel consumption. Also, a diesel engine is app. 25-30% more effiecient than a gasoline engine..resulting in increased fuel economy.

So, here’s what I know:

There are cases online of "homebrewers" who make biodiesel to fuel their diesel-engine cars.

Farms in general a lot of diesel engines.

People commercially sell biodiesel, but many farms don’t make biodiesel themselves.

Gas prices are going up, and depending on the system, the costs of making biodiesel (initial setup, methanol, lye/potash) can be lower than the price at the pump.

If farms have some restaurants or food chains nearby, would it make sense for them to use the cooking grease and make biodiesel to fuel their equipment?

I have found a site that boasts no engine modifications needed as well as by using their additive, you can use restaurant grease to fuel any diesel engine. Is that possible or true?

If anyone saw the episode of Pimp My Ride with red muscle car that ran on biodiesel, what kind of engine was it? Does that fuel run on any regular diesel engine, is it a different engine, or do you need to modify the diesel engine?

I saw some guys doing this on TV, and they were fueling up out of their garage! Can anyone do that? (Anyone with a diesel engine vehicle, of course.)

Yes, has anybody taken a diesel engine and converted it to biodiesel? Could you please explain to me how you did it, what supplies were needed, and roughly how much it costs to maintain a biodiesel. I’m thinking of getting a diesel to put in my Jeep and doing this but don’t know where to start. thanks!

I am researching the mechanics of making biodiesel and contemplating buying a ready-to-assemble processor. It sounds like a great idea but I would like input from people who already have experience with this.( For example, is it easy to make or is it a hassel? Does it work well in your diesel engine? How much petrol diesel do you have to mix with it in the winter?) Any opinions would be greatly appreciated.

I’m turning 16 and getting my permit next month and want to drive using biodiesel, vegetable oil, or something similar. I’m driving a 1983 GMC S-15 Pickup with a regular non diesel engine. Is their any way for me to make this take biodiesel?

Biodiesel is a renewable fuel produced from animal and vegetable fats that can be used in diesel engines with little or no modification. Biodiesel is typically blended with petroleum diesel in formulations referred to as B2 (two percent biodiesel, 98 percent petroleum diesel), B5 (5 percent and 95 percent), B20 (20 percent and 80 percent), etc. Though biodiesel is most commonly used in these kinds of blends, it can also be used in its pure form (B100). Biodiesel can be used in virtually any diesel engine without modification. It can be used in its pure form (called B100) or as a blend with diesel fuel at any ratio. The most commonly used form of biodiesel is a 20% blend of biodiesel with 80% petroleum diesel, known as B20. This has become a common practice as a balancing of benefits with costs, cold weather and solvency considerations associated with biodiesel. More on these below.) Biodiesel provides similar horsepower and fuel economy as petroleum diesel with superior lubricity to reduce wear and tear on the engine.

Biodiesel runs in any unmodified diesel engine. There is no engine conversion typical of other alternative fuels. The diesel engine can run on biodiesel because it operates on the principle of compression ignition whereby air is compressed and then fuel is sprayed into the ultra-hot, ultra-pressured combustion chamber. Unlike gasoline engines, which use a spark to ignite the fuel/air mixture, diesel engines actually use fuel to ignite hot air. This simple process allows the diesel engine to run on thick fuels. Since biodiesel is chemically similar to petroleum diesel fuel, you can pour biodiesel right into the fuel tank of any diesel vehicle. Biodiesel has many advantages as a transport fuel. Biodiesel has lower emissions, it is made domestically (which increases national security), it does not affect engine performance and biodiesel is produced from plants.

Biodiesel is registered as a fuel and fuel additive with the Environmental Protection Agency. The Departments of Transportation and Energy recognize biodiesel as an alternative fuel. An ASTM standard, D6751, has been developed to ensure biodiesel quality. Diesel vehicles has driving more than fifty million miles on biodiesel fuel in the United States, even more in Europe.
