How to Oil an Electric Motor
Expert advice: When oiling an electric motor, be sure to use oil that's specifically designed for motors.
When oiling an electric motor be sure to use special oil for lubricating electric motors. Other oils could cause excess wear and premature failure.
Buy special electric motor oil
Whenever you have to lubricate an electric pump, bench grinder or other electric motor, don’t pull just any oil off the shelf. Instead, pick up electric motor oil, like 3-In-One electric motor oil (about $3 at amazon).
Don’t use automotive motor oil! It’s too “thin” for electric motors. Plus, it contains detergent. If the excess oil seeps onto the motor windings, it might dissolve the insulation and fry the motor.
