I don't blend, but I have 30k miles on straight WVO with two tank heated fuel system.

i am an svo person as well, but i have done some research on blending. It seems like the main concern with blending wvo and #2 is that not all #2 diesel is exactly the same, some have various additives like for winter use, and in these situations there can be some strange reactions between the wvo and diesel. Something about waxes settling out, but it does not happen with all diesel fuels. If you want i can send you a link to a very long thread on another forum posted by someone named Warhorse who had this happen to him and it cost him thousands.
One way to approach this is to blend the two fuels in a jar and let it sit for a while and see what happens; another is to blend wvo and kerosene instead, as this seems to work better. According to a study done at the university of idaho, K-1 only requires about 2% wvo to bring it's lubricity up to standards so once you start adding more than that you have a pretty good fuel.

I am too lazy to go get that link, but go to biodiesel.infopop.cc and do a search for blend nightmare. That is the title of the thread.

Sorry I didn't respond sooner, I'm not here very often. In any case, I pulled an injector after 10k miles and saw no coking, haven't checked since. Coking is an issue only when you have incomplete combustion, which is only an issue when you inject cold grease into a cold chamber. Let things warm up and you should be fine.
