Believe me, I have changed a few! |
The tolerances in the CR diesels are irrelevant, if the filters keep debris out of the fuel system, you are fine. Biodiesel is a liquid with smaller molecules than a set of diesel hydrocarbons.
I've been burning B100 and blends in my Jeep CRD for 80k miles with no fuel related issues so far, aside from a gelling incident in below zero conditions. Not to say nothing will eventually degrade as a result, but there are lots of dead ones run on straight petro-diesel.
I hate the smell of diesel smoke too, but I have grown quite tolerant of the smell of biodiesel, much less acrid, and less visible too.
