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.
