91 or 93 octane is fine. i run it on my h22a's all the time and never have they pinged...nor have they failed emissions either.
And it was a JDM H22 engine?
Anyone with other info would help.........I've searched my ass off and came up with really not much......
I will be getting smogged tested in a month and then not for 2 years.........I also will be moving an a year to a no emissions state...(or they don't test the car annualy)
Thanks
