That's what I expect. But will it work anyway like he says?
I mean, regular WVO works fine(in the 7.3 IDI, anyway), if you can heat it up. If you lower the viscosity to the point that it doesn't need to be heated, then that solves the main problem, as well as(I think) creating less wear on the pump.
If the heavy fats fall out, then they aren't there to create carbon deposits and such, right?
