Burning BioDiesel that meets the ASTM D-6751 specification in your vehicle is safe. There have been well over 45 million miles of real-world driving with B20 blends in a wide variety of engines, climates, and applications. Our belief is if you are careful & follow the common sense guidelines spelled out in our book, you can make BioDiesel which can meet or come very close to the ASTM D-6751 specification.

Any diesel engine can operate on Biodiesel with no modification to the engine. Older vehicles often must have their fuel lines changed from natural rubber to synthetic rubber hoses. Using B20 (a blend of 20% biodiesel and 80% petroleum diesel) requires no precautions before use. If you want to use a blend higher than B20, such as B99.9, you will need to be aware of a few precautions before proceding. B100 is compatible will ALL diesel engines as long a few precautions are taken. See similar questions...

First, the quality of the biodiesel/glycerine separation. Second, doing a simple "miscibility" test your biodiesel with an equal amount of water in a jar. Thirdly by testing the pH of the fuel. See similar questions...

Biodiesel can be used in any diesel engine, typically with no modifications to the engine necessary. It performs comparably to diesel, with similar BTU content and higher cetane. It offers excellent lubricity and lower emissions compared to petroleum diesel. See similar questions...

Most major diesel vehicle manufacturers have already acknowledged that biodiesel will not void your warranty. Check with your dealer or diesel mechanic for further details. In the UK a 5% blend will not effect any diesel warranties. See similar questions...

Nothing. Simply fill your diesel fuel tank with biodiesel and drive away. If you plan on switching over to pure biodiesel it is important to understand its solvency properties. See similar questions...

Retard the injection timing by 2-3 degrees — this overcomes the effect of biodiesel's higher cetane number. It also causes the fuel to burn cooler, thus reducing NOx emissions. Petroleum diesel leaves a lot of dirt in the tank and the fuel system. Biodiesel is a good solvent — it tends to free the dirt and clean it out. Be sure to check the fuel filters regularly at first. Start off with a new fuel filter. Check there are no natural rubber parts in the fuel system. See similar questions...

Yes, possibly more due to its superior cetane rating. Biodiesel does contain 5% fewer BTUs per gallon than petroleum diesel, but burns more completely than petroleum diesel. Therefore, you get more energy from the fuel with less pollution. Partially burned fuel creates waste and more air pollution. See similar questions...

Many major engine manufacturers have made formal statements that the use of biodiesel blends under 20 percent will not void their warranty. For biodiesel blends over 20 percent, it is necessary to check with the manufacturer to see if there are any issues regarding their warranty. See similar questions...

In most cases you can start using biodiesel immediately without any modification. The only exception is older (pre-1990 diesels) may have natural rubber fuel lines which are susceptible to slow degradation with biodiesel. Just replace these with current synthetic fuel lines and you're done. See similar questions...

Biodiesel can be safely used in ANY device which can use #2 diesel fuel or home heating oil, including cars, trucks, tractors, generators, pumps, heaters and home furnaces. See similar questions...

Studies vary. Some laboratory research indicates slight increases in NOx by running biodiesel. Others find NOx neutral. Some claim that in "real-world driving conditions," NOx is decreased. Read more about our take on the NOx issue. Possibly. Anything in concentration can damage the environment. It is non-toxic and biodiegradable and it will generally degrade in the soil within 30 days from the time its spill, but the bottom line is: Don't spill it. See similar questions...

Scientific research confirms that biodiesel exhaust is less harmful on human health than petroleum diesel. Biodiesel emissions have decreased levels of polycyclic aromatic hydrocarbons (PAH) and nitrited PAH compounds that have been identified as potential cancer causing compounds. Test results indicate PAH compounds were reduced by 75 to 85 percent, with the exception of benzo(a)anthracene, which was reduced by roughly 50 percent. See similar questions...

We have seen a few occurrences where Biodiesel has actually been cheaper and the prices are continuing to get closer and closer together. That being said unless specific governmental regulation prohibiting petrol-diesel sales, or requiring Biodiesel sales is enacted Biodiesel will always stay slightly more expensive that petrol-diesel. Biodiesel is a direct substitute that is a higher quality product. It is a higher quality product because it produces significantly less environmental impacts. See similar questions...
