Can cars run on pure biodiesel?
Older injection pump diesel engines can typically use pure biodiesel without modification, whilst newer common-rail diesel engines can accept biodiesel blends of up to B5 (some can also accept B20) without issue. Be sure to check with your manufacturer as to the proportion of biodiesel that your vehicle can accept.
What are the problems with biodiesel?
The most common problems with fuel quality are (1) the biodiesel may contain some “unconverted”vegetable oil (incomplete processing), (2) traces of chemicals from the making of the biodiesel (e.g., methanol, lye) can remain in the biodiesel, (3) products of the reaction (e.g., glycerin, soaps) may not be completely …

Why is biodiesel not used?
The unaccounted for environmental problems that indirectly arise from biofuel use are significant: 1) direct conflicts between land for fuels and land for food, 2) other land-use changes, 3) water scarcity, 4) loss of biodiversity, and 4) nitrogen pollution through the excessive use of fertilizers.
Does biodiesel increase mpg?
If you have access to biodiesel, running a moderate biodiesel blend in your diesel engine may provide slightly better fuel economy and acceleration than conventional diesel, while costing about the same.
Can a diesel engine be used for biodiesel?
Also, newer diesel vehicle models of Volkswagen, BMW and Mercedes (2007 or later) have a fuel system that utilizes a Diesel Particulate Filter (DPF) that can create a fuel/oil dilution in the diesel engine, whether diesel or biodiesel fuel is used. Over time the engine oil could be diluted by the fuel if certain precautions are not taken.
What happens when you use 100% biodiesel?
The lower energy content of biodiesel translates into slightly reduced performance when biodiesel is used in 100% form, although users typically report little noticeable change in mileage or performance.
What does B20 stand for in biodiesel blend?
Blends are indicated by B##, which correspond to the percentage of biodiesel in the blended fuel. For example, a 20% blend of biodiesel with 80% diesel fuel is called B20. When biodiesel is first used in a vehicle, it may release fuel tank deposits which can lead to fuel filter plugging.
