A newbie here. I just bought a WVO conversion of a '59 190D, and am enjoying and learning and driving.

I have noticed that running pump diesel, when climbing a sustained grade at highway speed, the car will sputter and miss and "lose power".

Switching to veggie and looping around to tackle the hill again, there isn't even a hint of a miss or power loss.

Question - could the mechanical injection timing have been previously optimized for WVO, and that timing is not best for diesel when running at high engine speed?

Thanks -
