The following is taken from an email circular released by Tachopak:
From 1 April 2022 you must not put rebated fuel into the tank of a vehicle, vessel, machine or appliance that is not allowed to use it.
If you’re no longer able to use rebated fuel, you should plan to run down the fuel you have to as close to nil as reasonably practicable before 1 April 2022.
You may only use up rebated fuel after 1 April 2022, if the fuel was legally put into your vehicle or machine before 1 April 2022.
You can read the full email online at this [link].
