For those using their own vehicle the following mileage allowance payments apply.
For fully diesel cars generally add a 4% supplement (unless the car is registered on or after 1 September 2017 and meets the Euro 6d emissions standard) but the maximum is still 37%. For emissions over 75g/km if the CO2figure does not end in a 5 or a 0 round down to the nearest 5 or 0.
