It still pings on BP98. I use Repco 7.0 stuff. As I say 1/3 (or less) per tank o/wise it produces a lot of soot in the exhaust which can't be good. Seems to work. Southern BM said they start with the plugs when diagnosing and certainly indicated to me all M3's do it to some degree. I guess it would need to be detuned to the local fuel but no one is taking that on.
