I always find it funny to read the DIY bio-d posts and they say it turned out "perfect." What is perfect and how did you quantify it? That is my question.
I am by no means against bio-d, I like the idea, but there is an awful lot of misunderstanding and or misinformation about it. One thing for sure is if you run crappy fuel whether it is bio or dino, you will have problems.
You may have misunderstood what the term means. Same problem applies to ethanol, the ethanol can plasticise the pump and injectors. What that means is that the ethanol will cause the plastics to deteriorate, and then damage the copper windings. It does not mean the fuel solidifying...
