After not so lasting effect of lubegard Biotech and my oil just been used for 1.5k, I dumped the Suprotec Active Plus without draining.
The reason being is the website mentioned the suprotec supposed not to change oil property. First 150km, the effect like dumping LM MOS, seems the engine has a bit oil starvation, but after that suprotec cause louder noise when engine is cold. So now i need to be more patient on cold idling the engine before start moving off. However once it reach temperature, engine is very peppy and silent again. Let see how long the effect will last but i have no long distance high speed trip coming, so hopefully it can last the whole 10k oci like the combo zddp+mos2
