Shooters Choice puts up a red grease in a white syringe dispenser. I like this handy form of dispenser and can refill it with good quality grease. I think cleaning the mating surfaces after each outing and applying clean grease just before each use is most important to prevent carbon and other grits from damaging the gun - more so than a specific grease. Oil is a bit too thin for the heavy wear surfaces and runs away from where it is needed in hot weather.
