Mastering Oil Changes: Choosing the Right Oil Drain Plug Washer and Gasket

Performing a routine oil change involves more than just draining old oil and swapping out the filter. A small but vital component—the oil drain bolt washer or oil drain plug gasket—is essential for creating a proper seal and preventing leaks. Whether you're a DIYer or visiting an auto parts store like Canadian Tire, understanding the role of the oil bolt washer and how to choose the correct size (like the M14 oil drain plug gasket) can help protect your engine and avoid costly repairs.

Why Oil Drain Plug Washers and Gaskets Matter

An oil drain bolt washer (also known as a drain plug gasket or seal) is the small ring or gasket that sits between the oil pan and the drain plug. It ensures that once the plug is tightened, the connection remains leak-proof. While it might seem minor, skipping or reusing a worn washer can lead to slow oil leaks, gradual oil loss, and potential engine damage.

A properly installed washer:

Maintains a tight seal during high-pressure operation

Prevents oil leaks around the drain plug

Distributes torque evenly to avoid cracking the oil pan

The washer or gasket may be made of materials such as copper, aluminum, nylon, or rubber-coated metal, each suited to specific engine temperatures and materials.

Choosing the Right Oil Drain Plug Washer at Canadian Tire

Canadian Tire offers a wide range of oil change supplies, including oil drain plug washers and gaskets for various vehicles. Shopping in-store or online, you'll find options tailored to common sizes and material types, including copper and nylon.

If you're unsure of the exact size you need, check your vehicle’s manual or remove the old washer and measure the oil bolt washer diameter. Canadian Tire’s staff or website vehicle lookup tool can help guide your selection.

Here are a few examples of what you might find:

Understanding the Oil Drain Plug Gasket M14

The M14 oil drain plug gasket fits drain bolts with a 14mm thread diameter—one of the most widely used sizes in modern vehicles. These gaskets are typically available in several material types:

Copper: Offers strong sealing and heat resistance; ideal for high-performance or older engines.

Aluminum: Lightweight and corrosion-resistant; commonly used in OEM applications.

Nylon or rubber-coated: Ideal for low-heat applications and easy installation.

When replacing an oil drain plug gasket M14, make sure to:

Confirm the thread pitch (e.g., M14x1.5) if you're replacing the bolt as well.

Inspect the mating surfaces for damage before installation.

Always torque the plug to factory specs to avoid damaging the new gasket.

Tips for a Leak-Free Oil Change

Here are best practices for using an oil drain plug washer correctly:

Always replace the washer or gasket during each oil change. Reusing them increases the risk of leaks.

Clean the plug and oil pan surface before reinstalling to ensure a clean seal.

Use the correct size—using an undersized or oversized gasket may cause improper sealing.

Don’t overtighten—this can crush the gasket unevenly or strip threads.

In most cases, a new oil bolt washer costs less than $2 and can save hundreds in repairs if it prevents a leak.

Replacing the oil drain bolt washer or oil drain plug gasket is a small but crucial step in maintaining your vehicle. Whether you're using a M14 gasket for your sedan or looking for a universal fit at Canadian Tire, ensuring a good seal will help you avoid oil leaks and engine wear. Always match the correct washer size to your oil drain bolt and follow proper torque specs for the best results.
