That's a load of crud. Any good synthetic of the proper weight will be just fine. I run Mobil 1 and get my oil changed at the dealership. Knock is from premature detonation -- got nothing to do with the oil.
Only thing they really claim is superior about the Ester oil is for quieting valve chatter and I'm not sure I believe that.
