Semi trucks on SVO?
One thing i'm aware from reading elsewhere is that indirect injection engines are usually more suited to running straight vegetable oil than direct injection engines are, due to viscosity issues which become more important on for instance common rail modern diesels running 25k-30kpsi pressures. Heating the SVO makes it flow easier but i'd still question whether it would run on absolutely anything well.
I'm seeking opinions from anyone who might know about older semi truck engines - since they were direct injection before most others - about their potential suitability for SVO, whether anyone has ever heard of others running SVO, and similar. My guess is that the Detroit Diesel -53, -71,-92 type engines/the 2 strokes with their unit injectors would probably be the most resilent (I HAVE heard of SVO being run on them without issue) however they are not the most efficient - i'm curious whether anything newer might be able to run it without trouble.
