Bio-diesel, as it’s commonly made today is not suitable for modern piezoelectric injector systems. They operate at thousands of PSI and their orifices are not large enough to accommodate the thicker biodiesel.It will clog and ultimately destroy the injector systems.
Just ping FReeper Squantos, it happened to him.
Most manufacturers will void the warranty of any new vehicle that has had biodiesel damage. The manuals usually state emphatically THAT ANYTHING OTHER THAN REFINED DIESEL IS FORBIDDEN.
Older cars and trucks with MECHANICAL INJECTORS can use biodiesel just fine......
Yep...... 75 cent a gallon home brew was a $$$$ lesson in Scientific Wild Ass Guesses (SWAG) on that subject.
Buddy has a 300D mercedes, 82 I think that has two tanks. primary is refined pump diesel and aftermarket is “bio diesel and veggie oil system he bought. He runs it up for a few miles on pump fuel then switches over to his “blend” he says runs him a buck or less after all is said or done per gallon.
Then on his shutdown he switches over from his witches brew back to pump a few miles from home to purge the lines so it doesn’t crisco up on him while parked overnight or at work etc ....
As RB states........
Mechanical injectors and bio diesel ....good.
Piezo injectors and bio diesel IMO and bank account ....bad !!
