Oil does impact tensioner rattle.. This is in part to the way oils will retain pressure in their tensors, as well as how well the boundary layer protection is able to buffer the sound of the chains.

Oils high in Moly love tensioners. The best oil to quieten tensioners has always been redline. Our latest generation of DT40 is the best its ever been for this, as well.
