Why is this amazing? They are simply setting a standard. If all fuels clog injectors to some extent, then why not specify an acceptable limit on clogging?

I'm not sure RON has anything to do with detergency or vice versa.
I wasn't saying it does, but that in some places the gas doesn't even meet the octane standard, much less anything else.
