The Volkswagen Group does not authorize the use of B30 biodiesel in any of its vehicles. B30 Biodiesel is a blend of 70% fossil fuel and 30% biofuel derived from Fatty Acid Methyl Ester (FAME). The use of this fuel in Volkswagen Group vehicles may void the engine and exhaust system warranty.
Biodiesel and conventional diesel vehicles are one and the same. Although light, medium and heavy diesel vehicles are not technically alternative fuel vehicles, almost all are capable of running on biodiesel blends.
One of the biggest problems we biodiesel manufacturers have seen recently has nothing to do with the conversion process – it has to do with diesel engines. Up until two years ago, all diesel engines were B100 capable (biodiesel cannot run in gasoline engines as it needs an engine that uses compression ignition).
Although most diesel engines (at least in mild weather conditions) can be started and run for a few hours on biodiesel fuel, engine manufacturers restrict the use of biodiesel in many engine models to ensure there are no adverse effects over the life of the engine< /b>.
Diesel engines designed to burn standard diesel fuel must be modified to burn pure vegetable oil: The vegetable oil must be heated to around 160°F before it is pumped through the injectors – this is to reduce its viscosity to about the same as standard diesel fuel.
To date, available test data shows that biodiesel can actually help reduce deposit formation in some older engine designs that use indirect injection systems with lower temperatures and pressures.
If you have access to biodiesel, running a moderate blend of biodiesel in your diesel engine can provide slightly better fuel economy and acceleration than conventional diesel, at around the same price.
B20 with 20% biodiesel has 1% to 2% less energy per gallon than petroleum diesel, but many B20 users report no noticeable difference in performance or fuel economy. Biodiesel also has some emissions benefits, particularly for engines manufactured before 2010.
“The raw materials you need to make biodiesel are more expensive than petroleum,” said Jones Prather. “In addition, the processes for manufacturing the fuel are not yet efficient enough to produce it very cheaply.”
Vegetable oils such as palm, soybean, sunflower, peanut and olive oil can be used as alternative fuels for diesel engines. As an alternative fuel, vegetable oil is one of the renewable fuels.
Firstly, you can only use vegetable oil in a diesel engine, not in a petrol engine. However, it is important to note that oil should not be poured into a car straight from the bottle. Because the oil is so thick and sticky, it doesn’t flow properly through the engine and doesn’t burn efficiently.
It turns out that the simple design of diesel engines allows virtually anything oil-based to be used as fuel. The engine’s inventor, Rudolph Diesel, used peanut oil in his original design.
Biodiesel significantly increases the potential for injector deposits. In particular, the sodium used as a catalyst in the manufacturing process contributes to the formation of metal carboxylate deposits in the injector, which can reduce engine performance and performance and contribute to injector failure.
Biodiesel is rarely used in its pure form. It is usually blended with diesel and is identified by the amount of diesel it is blended with. In fact, some biodiesel is typically found in almost all “regular” diesels sold at gas stations in the US, in blends up to B5, says Edmunds.
And now I’m discovering you can drink it. Randall von Wedel, a biochemist who has become one of the staunch supporters of biodiesel, points out that it is just vegetable oil with some molecules removed. It smells a bit like old olive oil and might give you a tummy ache, but it won’t kill you.
Yes, you can use biodiesel and diesel fuel interchangeably and mixed.
