CJ,
I was reading a research document (some university) today that detailed how multiple manufacturers had studied both WVO and WVO/#2 mixed and found serious problems with injectors fouling when used in direct injection systems (like ours).
It would help a lot of us (and you I'd think) if you could periodically pull an injector or two for inspection.
The failure mechanism seems to be related to the higher viscosity (thicker) oil and how it affects the injector's spray pattern - the poorer pattern causing unburned fuel and therefore soot buildup in and around the nozzles.
If yours remain clean, it would really vindicate DSE's claims to improve the fuel's ability to be sprayed into the cylinder with a reasonably good pattern. And give you (and those considering following in your footsteps) some peace of mind when considering the cost of engine repairs...
?Thanks!
Mark
