My youngest son just got a 2005 Focus ZX5 with only 112K km (65K miles) and he says there is a slight whine when speeding up or on coasting down....cruise is fine . I suggested he try a synthetic lube in it , one in part to maybe help the noise but the 2nd reason he is in the northern part of Ontario and they will be getting some cold temps in the winter so it should make shifting better .
Any suggestions on what might help the noise and be a suitable gear oil for that tranny ?
