How to Choose the Right Thread Size for Your Car Oil Filter

When it comes to changing the oil filter on your car, one of the most important things to consider is the thread size of the filter. If you choose the wrong thread size, the filter may not fit properly, which could lead to leaks and other problems. In this article, we will discuss how to choose the right thread size for your car oil filter.

Step 1: Check Your Car Owner's Manual

The first thing you should do when choosing an oil filter is check your car owner's manual. The manual will tell you what type of filter your car needs, including the thread size. If you don't have the manual, you can usually find the information online. Just make sure you know the make, model, and year of your car.

Step 2: Measure the Old Filter

If you don't have the owner's manual or if you want to double-check the information, you can measure the old filter. Use a measuring tape or ruler to measure the diameter of the filter and the length of the threads. Make sure to measure from the base of the filter to the top of the threads. This will give you an accurate measurement of the thread size.

Step 3: Choose the Right Thread Pitch

In addition to the thread size, you also need to choose the right thread pitch. Thread pitch refers to the distance between each thread on the filter. Most car oil filters have a pitch of either 1.5 or 1. The pitch is usually stamped on the filter or listed in the owner's manual.

Step 4: Consider Your Driving Conditions

When choosing an oil filter for your car, you also need to consider your driving conditions. If you drive in extreme temperatures or harsh conditions, you may need a filter that can withstand these conditions. Look for filters that are rated for extreme temperatures or that have a high-efficiency rating.

Step 5: Choose a Reputable Brand

Finally, when choosing an oil filter, it's important to choose a reputable brand. Don't just go with the cheapest option or the first one you find online. Look for brands that are known for their quality and reliability. Some of the top brands include Fram, Bosch, and Mobil 1.


Choosing the right thread size for your car oil filter is essential for proper function and performance. By following these steps, you can ensure that you choose the right filter for your car. Remember to check your owner's manual, measure the old filter, choose the right thread pitch, consider your driving conditions, and choose a reputable brand. With the right filter, you can keep your car running smoothly and efficiently for years to come.
