I really have seen no difference in ither really. I can get 5 quarts and a good filter for like 25 bucks on sale..a little better that the 7.99 a quart +tx for royal purple. Anyone have a difference of opionion.
A motor capacitor, such as a start capacitor or run capacitor (including a dual run capacitor) is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field. 440 volt capacitor can be used in place of a 370 volt, but not a 370 in place of a 440 volt. The capacitance must stay the same within 5% of its original value. Round cylinder-shaped dual run capacitors are commonly used for air conditioning, to help in the starting of the compressor and the condenser fan motor.
Many electrical devices use some type of capacitor, including a furnace blower. A capacitor is a device that stores an electrical charge. A start capacitor is typically found on an air conditioning unit or heat pump where extra torque is needed to start the compressor.
