Hi can anybody help, I have a late 2007 A4 2.0 TDI and was considering switching to Biodiesel but wasn't sure if my car would run ok on this???

 

It depends upon the source of the biodiesel; as a general rule I'd say take a pass and run on regular diesel.

 

go to a car shop. you must have a diesel motor in your car first. after that you go to a shop and ask them. Following that you must have enough vegetable oil. Once you have that new diesel filter installed your car automatically cleans the oil that you put in. keep in mind that this does cost money.

 

Out of curiosity, can biodiesel be used in engines requiring ultra low sulphur fuel? If so, in what maximum concentration?

Thanks in advance.

 

First things first; I believe biodiesel is by definition, completely sulfur free. The bigger issue here is the lubricity; too low (a metric that varies by engine) and you shouldn't use it.

 

Thanks. That's what my gut told me.
