Can I use biodiesel in a bluetec diesel engine? Will it harm the engine, the after-treatment, or the PM fltr?

Question

I own a 2006 Jetta TDI and want to upgrade to a bigger passenger diesel and want the BMW X5 bluetec diesel when it comes out. I only want it if I can run biodiesel B20 or B99 in it without harming the vehicle. I'm not interested in the manufacturer's lame, conservative position and warranty statements. I want to know if it will actually cause probelms with the bluetec technology. Thank you in advance.

Answer 1

well you can be a test subject and post your results on them web for the rest of us?

Answer 2

its hard to say after making my own bio diesel and having it actually clean up my engine i would say no

I did actually think that all new cars do have to be able to use biodiesel

however if the engine uses parts that can corrode by using biofuel that may cause serious probems

If not and the warranty is an issue especially for an expensive new car when it has to go in for a service just run low on the biodiesel and then fill up with regular a week before you get serviced and no one will know

Answer 3

Some folks say bluetec engines will and others say they won't:

It does:

It doesn't:

Ask the dealer and see if it will affect the engine warranty.

There is a difference in the characteristics of biofuels and petroleum fuels that can affect engines and the seals if they are not engineered for both fuels.
