Gulf Competition 10W-40/15W-50 plus Polytron MTC additiv in Mini R56 JCW GP2

Please compare with the other video from me about "Gulf Competition 10W-40/15W-50 with WS2-E Engine-Oil-Upgrade additive in Mini R56 JCW GP2". If you listen with a headphone or loudspeaker, you will hear a difference. The MTC additive from Polytron sounds a little bit deeper, maybe calmer.
