Electric motor oil
Pick up a can of electric motor oil. It's specifically designed for electric motor use.
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.
