Thread: StraightCooking Oil into the Tank

From memory it is something to do with the mechanical strength/design of some pump components.

By coincidence, this afternoon I came across a warning label attached when new to a S3 diesel that I have. I think it is worth quoting in full:-

WARNING

This engine must not, repeat not, be started if the prevailing temperature is at or below freezing point, or the injection pump may seize up.

Inhibiting fuel, Fusus A or a mixture thereof, is used in this system, and freezes at between 22F and 30F.

The whole engine must be raised above the critical temperature before starting and normal diesel fuel used to replace the above mentioned fuel, after which the vehicle can be safely started in prevailing conditions. The engine may be considered as satisfactory for starting when, upon undoing the vent screw on the distributor pump, liquid fuel may be pumped from the tank by operating the fuel pump hand priming lever.


This certainly suggests that you will get problems if you use fuel with too high a viscosity, but also tells you how to tell whether you have got too high a viscosity.

Me too Capstan! I thought it would be a hoot to run my series 1 on charcoal and go to the local show. The gas producer along with the fuel could be in a trailer. Let me know if you find any plans, I will do likewise,
