Here's what someone else said:
That comment was not specific to Powerstrokes. I don't mean to sound argumentative, it's just that all these comments have all but scared me away from using Biodiesel, and if you can refute them, then I don't have to be scared anymore.
Bulk modulus is too little...it is less springy than petroleum diesel. In lower pressure systems, this isn't an issue. Distributor systems have plenty of spring in the lines. But in unit injectors, it is damaging to most components as the pressure spike is sharper.
In electronic distributor systems, it can cause accelerated corrosion in the control collar position sensor, fuel temperature sensor or timing circuit. There, fuel pressure inside the case is regulated to set the timing dynamically. These pumps have a good bit of electrical wiring going into the pump, the bulkhead connector may NOT tolerate it either. It likes to destroy wire insulation, leading to a trashed IP. Meaning YOU PAY CORE CHARGE, $400 in most cases or more.
I've seen plenty of pumps running commercial bio which were coated with varnish. If you run 100%, always flush the system with petro diesel before stopping.
