Mine is about 105k now.. Did 100k service recently, change spark plugs and EO (Motul 300v). Change tires as well, Kumho KH31, original rim size.
I also on Esso but is 95. Tried 98 once, feel pick up more powerful.. but negligible, and did not not improve FC. So switch back to 95.
My rpm usually hover around 2rpm.. cause already 60-70km/h after holding it there for a while. Sometimes moving off from red light will go about 2.5rpm if see beside lorry/bus overtakes me....
