Everything You Need to Know About Oil Crush Washers

When performing an oil change, many car owners overlook one small but crucial component: the oil crush washer. Whether you are changing the oil in your car yourself or working with a mechanic, understanding the role of the crush washer is essential for a successful oil change. In this article, we'll discuss the significance of the 12mm crush washer, the drain plug washer, and other related types, ensuring your oil change is leak-free and smooth.

What is a Crush Washer and Why Do You Need It?

A crush washer is a small, round washer made of soft metal (usually copper or aluminum) that is placed between the oil drain plug and the oil pan during an oil change. Its primary purpose is to create a tight seal to prevent oil leaks. The washer compresses when the drain plug is tightened, forming a secure seal that stops oil from seeping out after the change is complete.

The Importance of the 12mm Oil Plug Crush Washer

One of the most common sizes for oil drain plugs is 12mm, which is why the 12mm crush washer is frequently used. This washer fits snugly around the oil drain plug, ensuring a proper seal. Over time, crush washers can wear down or become deformed, which may lead to leaks if not replaced during each oil change. Always replace the oil plug crush washer with a new one to maintain the integrity of the seal and avoid oil leakage.

Where to Buy Crush Washers for Oil Changes

If you need a drain plug crush washer, the good news is they are widely available. Many auto parts stores, such as AutoZone, stock these washers. You can find crush washers in various sizes to match different drain plugs, including the 12mm size. It's recommended to purchase high-quality washers, such as those made from aluminum or copper, to ensure a reliable seal. Most washers are inexpensive, but they are essential for preventing costly leaks or engine damage.

Replacing the oil plug crush washer is a small but important part of routine car maintenance. Whether you're using a 12mm crush washer or a different size, it's crucial to ensure a secure fit to avoid oil leaks. Don’t forget to pick up your new drain plug washer at your local AutoZone or auto parts store the next time you change your oil. Keeping this small but essential component in mind will ensure your oil change goes smoothly and your engine stays protected.
