I can tell you one thing, I will NEVER put bio-diesel in either my car or truck’s tanks.
That stuff is junk ... pure and simple.
Very bad for the fuel system.
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......
