I've contacted the frybrid guys and I guess they're very busy because i'm not getting the help i need from them. Here's my thread I've been updating for 2 months:

This install was actually performed by Chris, my car is the green E300 on his web site.

My WVO is professionally cleaned by the guys at Diesel Green Fuels. THey've been doing this for years so I trust that they know what they're doing. Besides, if I take VO out of the equation, if I don't even switch over to VO at all, the car will have the same startup symptoms:

Cold start: 3-6 seconds of cranking
Warm start: 6-9 seconds of cranking
HOT start: 60-90 seconds of cranking
