my husband put Caterpillar 40 oil in my car
Well tell him to take it out, its the wrong oil and do a complete oil change including a new filter and refill with 5W-20 Synthetic Motor Oil (ALMQT), DO NOT DRIVE THE CAR WITH THIS OIL IN IT !
Yes get it out, diesel oil is not for gas engines and you can damage the engine by driving it, complete oil and filter change ASAP.
