I never, ever use any cheap gas! BP Ultimate or Shell V-power is all I EVER put in my tank. I am sure however, that there are some E46s on the road that have enough ring and valve/valve seat wear that dropping down to a GOOD (read; NOT CHEAP) mid-grade fuel, would not cause any pre-ignition due to lower compression that the worn rings and valves cause.
Feeling a difference means<nothing, placebo effect! Higher octane has been proven to provide NO increase in hp/tq in numerous dyno tests!
