davidnormanuk - I let the car idle for bout 30-45 seconds when starting from cold.

Would letting it warm up change what oil to use ?


Not sure if another problem I've had relates to this (I've posted on multiple forums before about it), but sometimes when going uphill in a high gear at low revs there's a tappety sound, but also smoke appears from the exhaust (I've only noticed the smoke once, as each time I hear the noise I let off the gas)
