Vauxhall

E10 petrol is cleared for use in all Vauxhall vehicles with petrol engines, excluding:

Models with the 2.2 litre direct injection petrol engine, motor code: Z22YH (Vectra, Signum, Zafira) which should continue to use E5 petrol.

I'm still not sure if my vehicle is E10 compatible

If you're not sure if you can use E10 in your vehicle:

check the vehicle owner's manual, the instructional booklet is specific to your vehicle
look inside of the fuel filler flap
ask the car, motorcycle or scooter manufacturer / local dealer

If you're still not sure, use E5 petrol. It will still be available in the super grade at many filling stations.
