Choosing the Right Crush Washer for Your Oil Drain Plug

When it comes to changing your car’s oil, one small but essential component is often overlooked—the drain plug washer. This tiny part plays a crucial role in preventing oil leaks and maintaining proper pressure within the oil system. Whether you’re using an aluminum drain plug washer, a crush washer M12, or looking for a crush washer at Advance Auto Parts, knowing which one fits your vehicle can make all the difference.

What Does a Car Drain Plug Washer Do?

A car drain plug washer is a sealing ring placed between the oil pan and the drain plug bolt. Its job is simple but important: to create a tight seal and prevent oil from leaking once the bolt is tightened. Without a proper seal, engine oil can seep out slowly, leading to low oil levels and, over time, potential engine damage.

These washers come in different materials, with metal options like copper or aluminum being the most popular. The aluminum drain plug washer, for instance, is known for its durability and excellent sealing properties under high heat and pressure.

Choosing Between a Crush Washer M12 and a Crush Washer M14

Not all crush washers are created equal. Two of the most common sizes are the crush washer M12 and crush washer M14, which correspond to 12mm and 14mm drain plug diameters, respectively. Using the correct size is crucial—too small, and it won’t fit; too large, and it won’t seal properly.

A crush washer M12 is typically used in smaller engines or compact cars, while a crush washer M14 fits larger vehicles or those with bigger oil pans. Always refer to your vehicle's manual or consult with a professional if you're unsure about the correct size.
