I've tried that and the noise gone, what caused that noise you reckon? I am thinking it is to do with the preload in the transaxle and driveshafts as you stop (the resulting torque could affect the engine mount / isolator performance). Stopping whilst in neutral, then shifting to drive is also good, per the above neutral trick. The rpm before and after shifting to neutral is exactly the same, so nothing to do with that. The vibration does not return for me. I have been using BP Ultimate 98 since new, so no difference there either.
