I have my own feelings on oils and ATF and all ... But one thing know one ever brings up is "foam" ...As in oil putting off or turning into "foam" ... Air in oil is a killer <img src="/forums/images/graemlins/zombie.gif" alt="" />...

Montys do to the gearing and the auto trans work and are made can really get oil to foam .. You guys using Mobil 1 look at the stick and see if theres 'foam' or 'air' drops on the stick ...
