I keep some SAE 140 in an oilcan, as this is the best way I have found to get it into the rear diff. However, the fact that it is in an oilcan means I use it for topping up the steering box ( seems to stop unsightly grease marks on your trousers!) and for general oiling duties underneath. I reckon that the thicker the oil, the more likely it is to stay put.
