Thermo Top E and Z/C
Propellant for Thermo Top Z/C (Fuel):
The proper fuel is the fuel specified by the vehicle
manufacturer
Propellant for Thermo Top Z/C (Diesel):
The proper Diesel fuel is the one specified by the vehicle
manufacturer. When switching to low temperature
propellants the heater must be operated for at least
15 minutes to prime the fuel pipe and pump with the new
type of fuel.
A persistent influence by additives is not known.
