Thanks for the info man!

I'm currently running 10%new sunflower oil and 90% dinodiesel in my om602 turbo. THe car runs the same as with diesel, if not better. I don't have problems with too loud clatering or smoke (touches wood) so vo didn't affect anything except what my exhaust smells.

I plan on increasing the vo/diesel ratio a lot during summer. I already bought resistance wire, so i'll heat the injector lines and spin on fuel filter. Fattywagon claims that his injector heaters are 100w, but today i tried with a bit lower than 50w heater and within 5s it was so hot that I burned my fingers when i touched it (had to try it somehow and didn't excpect it would be so hot so fast). But for the first time I was sort of happy that I burned my finger . This means that I can heat both my injector lines and spin on fule filter using around 100w.
