You can put normal in if no choice but only to get to a garage with super,the main issue is if you have normal in dont go over 4000 rpm as the ecu detects normal fuel and pulls the timing back a little but the damage can be caused over 4000 due to causing a knock due to timing and no anti knock protection over this there is a thread some where explains it better but below 4000 will be oki to get you to some super or you can get it remaped to run on normal with not problems as timming changed to acount for this
