A lot of people have passed that sign over the years :-)
I am running on Bio Diesel now (about B80 due to having D2 remaining).
I do wish that I was not transitioning to Bio-Fuel just as it is getting cool here; I'd like to have some Data, but it is what it is.
I do have a spare fuel filter in the trunk allong with tools in case the filter plugs up. I want to get a fuel filter minder;
Automobile Parts, Fuel Filter, Air, Monitor, Car Accessories, Engineered Products but I guess that's going to have to wait.
What I'm working on now is having things more streamlined and efficient; because at this point I'm still doing a lot of fluid movement by using 5 gallon buckets, and my wash / settle capacity is low.
