sticking to Caltex since I get my new cx5 until now.
ron 97 smoother ride
ron 95 less responsive compare to ron 97 (ofcoz la)

previously use esso, however since I realize its related to dr.m, I force myself to switch to Caltex, never regret since then.

haven't got a chance to try on bhp petrol. mayb 1 day I ll.

actually its the same la.
more power = more fc, that's the nature.
