Okay, but it seems the people having a problem in this thread are those that are NOT from California. It seems you have no business being in this thread anyway, it is for those in California only. =-)slab42 said:yes, yes we know that, he is saying not to start another thread about octane levels and which one to use... there are enough of them on this site already. If your RR is stock, no need to use anything but the cheap stuff... if you have pinging from cheap stuff it is either bad gas, or you have aftermarket mods to your bike that require you bump up to a higher octane. The bike is designed to run on 86, where as your A4 was modded, and therefore "designed" to use higher octane.
Please everyone, lets stay on topic here, the title of the thread is "question about OCTANE rating here in cali...not a debate thread! lol "
don't offer opinions/facts about which octane rating to use, the thread is about the differences in rating methods.
pure isooctane is 100 RON, fyi. just thought i'd throw that in there =)madbrown75 said:It is possible for a fuel to have a RON greater than 100, because isooctane is not the most knock-resistant substance available.
