Mon, 13 June 2005 05:40 Hi, Matt-itude wrote on Mon, 13 June 2005 04:40 If your car runs perfectly fine with no detonation on 91 RON, then putting a tank full of higher octane fuel will not do anything for performance. IF NO OTHER MODIFICATIONS ARE DONE So i stand by my statement: Matt-itude wrote on Sun, 12 June 2005 19:11 Better performance from BP ultimate? All things staying the same, i don't think so. Technically, your statement is not correct. As evidenced by the posts in this thread there are those among us who do get improved performance in running 98RON (ie Ultimate, etc) in our engines. Your statement would be more accurate if it was "98RON has the same power potential (or words to that affect) as 95 or 91RON" Or, better still... "98RON fuel won't give you anymore power in your engine if your engine is designed and tuned to run 91RON" Even then, I'm sure there are people who have 91RON-tuned engines and have found their motors running better on 98RON. But a blanket statement such as "Better performance from BP ultimate? All things staying the same, i don't think so." is simply wrong. Unless you add the disclaimer that this statement is only applicable to lower compression 91RON-tuned engines. As I mentioned earlier, my car pings it's butt off on 91RON. It pings less on 95RON, and it sings sweetly on 98RON. So, all things being equal (ie same engine, no or tune-ups between refills, etc), 98RON (Ultimate) does offer me better performance. You said that 98RON has the same "potential energy" as 91RON, however it's the "kinetic energy" that actually provides the power to drive your engine, and in this regard the 98RON is superior to 91RON, specifically in a higher compression engine. seeyuzz river [Report message to a moderator]
