It is OK if some of us disagree as that is the American way. I run Bio D and I am in the process of setting up a 2 tank for my bus with a 6V92 Detroit. If all goes well I will have the last of the work done on the Detroit tonight. The first valves I tried on it dod not allow enough oil flow to feed that beast. I bought some SV200 valves from GReasecar and I will have them hooked up by 6 PM tonight. We shall see!!
