Can I store rebated oil in auxiliary (belly) tanks on a vehicle or trailer?
Yes, but only in fuel tanks not capable of connection to the engine used to propel the vehicle (unless it is an excepted vehicle). The standard running tank(s), whether connected or disconnected, must contain only fully duty paid fuel. Rebated gas oil must not be taken into the standard running tanks or auxiliary tanks fitted to vehicles or trailers except where these tanks are solely and permanently connected to the auxiliary machinery (for example, refrigeration motors). All other tanks on a vehicle, trailer or bulk carrier whether directly connected to the propelling engine or not, will be considered to be part of the road fuel system. Dual fuel systems are not permitted, even where they can connect to a power take off to switch the tanks.
