robm Posted February 23, 2012 Share Posted February 23, 2012 But what is "octane" in this case? Research, Motor, or the standard at the pump, (R+M)/2? My bet it is Research, because I can't see why a low compression engine like an EA81 (8.5:1) would need (R+M)/2 = 90, which is a midgrade or even premium, depending on the market.
