I have a 2003 Mazda Astina 323 Shades, and i've been using E10 for a few yrs now. I've just found out from Mazda i should not have been using E10. I would like to know from you, is there anything I need to do before I start using unleaded, or shall I wait until the petrol in the tank goes down, and start using unleaded.
Your help would be appreciated.
Keep up the good work on 2UE.
