Castrol is a top name in lubrication and this is a product that I have used for many years. The latest form only seems to come in cartridges which is convenient if you have a grease gun to suit. It is not so handy if you want to just smear a little on sliding parts, fill a smaller grease gun or pack a bearing. The excellent friction reducing properties of the moly additive and cling characteristics make this the best choice for many applications.
