How do I know how much grease to inject into a fitting?
Over-greasing is as damaging as under-greasing, excess pressure blows the grease seal and expels the grease that was protecting the bearing. For most automotive and light-equipment zerks: inject until you see fresh grease appear at the seal lip. Count the number of pumps and record it for future reference, a wheel bearing might take 3 pumps, a U-joint 1 pump. For fittings with a grease nipple that vents: pump until the vent releases. Do not force grease against resistance, if a zerk feels blocked, switch to a needle coupler and check the fitting before continuing.
What type of grease should I use?
NLGI grade 2 multipurpose lithium grease handles most automotive chassis, wheel bearing, and general purpose applications. For high-temperature applications (brake components, oven conveyor bearings): use a high-temp red grease rated for the operating temperature. For marine or wet environments: a water-resistant marine grease. For food-processing equipment: NSF H1-rated food-grade grease. Do not mix grease types, different base oils and thickeners are chemically incompatible and can break down lubrication properties. If switching grease types: purge the old grease fully before switching.
