Just pump in rm10 when your tank empty. It would mix with some of your remaining ron97. Then when finish pump rm10 ron 92 again. Keep doing until you feel that all your old ron97 gone. Then pump till full tank or normally what you pump lah. If you pump rm10 and got problem or on the way to full ron92 got problem just stop pumping ron92 lor. It wont kill your engine. Just not that smooth and slightly noisy.
