If that the case, I am driving ML320..I will approve for it. That the way all business conducting now a day...either you have connection from ML so Mobil will have a easy approve ( Mobil same way) otherwise time will tell. or when they can smell more profit...it will have an approve from either side as an eye blink

I had been work very close with German company and do know how they worked. Did couple research on the new oil ...."Mobil 1 Extended performance" the result very impressive.
One question...about AMSOIL...it seem very good but it is not at the regular store such as pepboy, autozone, etc...Don't know why? if you do please give me some light here. ( not Budlight).

Thank you for all good and execelent feedback. Do learn new stuff.
