Hi guys, Quick question about fuel for an 09 1125 CR. I'm from South Africa so hopefully this all makes sense. I've hunted round the forums a bit but it seems we have a different naming conventions for our fuel. Our choices here are 95 LRP (lead replacement) and 97 unleaded. A mechanic here recently suggested running on the 95 LRP, stating the bike will have a lot more punch and run better overall. I just feel a bit apprehensive about this. I have very little experience in this area. Any help/suggestions are greatly appreciated. | ||

Lead and O2 sensors typically don't play well together, so if you run it, plan on changing them out regularly. | ||

You'd want the higher octane 97 anyway (if that's what 95 and 97 are referring to). | ||

I would run the '97....there are no vehicles in the 'states that run on leaded anymore, I can't imagine fuel for leaded vehicles (lead or no) would be food for it. Mine doesn't even like "regular" low octane gas. | ||

I wish we could buy 97 octane at normal gas stations in the states. I wonder if it's the same thing and the rating system is just different... There are two methods of determining the octane (I'd assume one by volume and one by weight) and the octane listed at the pump in the US is the average of the two. That's why the sticker always says (R+M)/2 method... I wonder if the gas in SA is only rated with one method or the other and that's why the number seems higher. | ||

According to this wikipedia article, South Africa uses RON (Research Octane Number) for rating octane. In the US. we use R+M/2 (also called anti-knock index- AKI) which is the average of the RON and the MON (Motor Octane Number). The RON number will typically be 4-5 points higher than the R+M/2, so 95 octane in South Africa should be about the same as 91 octane in the U.S., and the 97 octane should be about the same as 93 octane in the U.S. Based on octane rating, either of those should be OK for an 1125. http://en.wikipedia.org/wiki/Octane_rating I'm guessing that LRP has something other than lead in it to replace the lead, but it would still be worth doing some research to make sure it's not something that will screw up the oxygen sensors. |
