I am confused! =-/ I put in the best that they have at the pump. My baby only takes a few gal. to fill, why be a cheap ass?! I'm use to the prices, I've always had to use premium fuel in my modded Audi A4. I have custom mapping that requires high octane.

James, you might have just sparked the debate.. do your research and come back..

Why should I research? I have to use 91 in my car because my Eprom requires that octane and the manufacturer suggests it for advanced timing. If you use lower in my car it pings. The software designer of my chip states specifically to use 91 or higher at the pump. Higher octane fuel has only one beneficial feature - it allows an engine to run at higher temperatures with more advanced ignition timing under higher levels of compression witout detonating / knocking. Also, I found that in my cars over the past 20 years lower octane gas causes a build up of crud around the injectors. Although I hear that the newer gas today, in lower octanes, no longer causes that crud. I use 91 in the 600RR because that is what I have always put in my bikes, but this is the first newer generation bike I have owned. I do know that 91 seems to run good in my bike, no problems that I have noticed. It also is a good idea to use a gas with an addative, like Chevron w/Techron. I have read and heard from people who say that a low octane fuel causes their RR to ping or knock. I also get excelent mileage using 91, but I'm not saying I wouldn't with 87...I don't know.

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.

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. =-)

If you are going to use low grade, buy "good gas". Meaning, at least get it at Chevron, Mobil, Shell, etc. NEVER use Thrifty gas or the like. It does show on a sticker under the pass seat that we have a MIN 91 RON sticker. That is we are to use 87 at minumum but certainly can use higher grade if we so choose. Remember friends from outside California, we have crappy gas here that is oxygenated and extra refined due to our California clean air act. We are known for crappy gas, so I choose to put in the best of the crap. =-)
