i don't really get it. how can you get 180 on 3rd gear and 4k RPM. fuel change doesnt do a thing to the gear ratio. my car, 120 on 5th and already 4k RPM. i get around 10km/lI think it the fuel in Malaysia making this knocking problem. With 95, I had to very2 slowly open the throttle to minimize the knocking. With 97, I can open hard, but if too hard, then the knocking will start....
But with 100 and 1++, I can do anything without any knocking at all. Plus, I can get 180km/h in third at only 4,000rpm and still get 14km/l. 20v not lagi best, but best giler.....
