Finding your Mobil 1 filter starts with your vehicle's year, make, and model

Mobil 1 makes oil filters for most vehicles on the road, but the part number you need depends on your specific engine. You cannot buy a Mobil 1 filter by brand alone — you need to match it to your car's requirements. The fastest way is to use Mobil's online filter finder tool, enter your vehicle information, and see which Mobil 1 filter is designed for your engine.

If you prefer to shop in person, you can also take your current filter to an auto parts store and ask staff to match it, or provide your vehicle details at the counter and they will look up the correct part number. Many stores keep Mobil 1 filters in stock because they are widely available, so you should be able to find what you need the same day.

Key Takeaways

  • Mobil 1 filters are labeled by part number, and the correct number depends on your vehicle's year, make, model, and engine type.
  • Mobil's online filter finder tool lets you enter your vehicle information and returns the exact Mobil 1 part number you need.
  • Auto parts stores can look up the correct filter using your vehicle details or by matching your current filter.
  • Mobil 1 filters are sold at most major auto parts retailers, big-box stores, and online marketplaces.
  • Keeping your filter part number written down saves time if you need a replacement later.

Using Mobil's online filter finder

Go to Mobil's website and locate their oil filter finder tool. You will enter your vehicle's year, make, and model, and sometimes the engine size if the system asks. The tool will return one or more Mobil 1 filter options — usually there is one correct choice, but some vehicles have multiple engine options that use different filters.

Write down the part number shown. This is the identifier you will use when you shop, whether online or at a store. The part number typically starts with "M1" followed by numbers, such as M1-110 or M1-113A. Bookmark the page or take a screenshot so you have it handy when you are ready to purchase.

Matching your current filter at a store

If you already have an oil filter in your vehicle, you can remove it and bring it to an auto parts store. Staff will look at the part number printed on the filter's label and cross-reference it to find the Mobil 1 equivalent. This method works well if you do not have your vehicle information handy or if you want to confirm the filter size in person.

To remove your current filter, you will need an oil filter wrench and a drain pan to catch any oil that spills. Loosen the filter by turning it counterclockwise until it comes free, then take it with you to the store. Staff will match it and tell you which Mobil 1 filter replaces it.

Where to buy Mobil 1 filters

Mobil 1 filters are sold at most major retailers. Auto parts chains like AutoZone, O'Reilly Auto Parts, NAPA, and Advance Auto Parts stock them in their stores and online. Big-box retailers such as Walmart and Target carry Mobil 1 filters in their automotive sections. You can also order them from online marketplaces like Amazon.

Prices vary slightly by retailer and filter type. Mobil 1 makes standard filters and extended-drain filters designed to last longer between oil changes. Check the part number on the package before you buy to make sure it matches what you looked up. Most stores will accept returns if you purchase the wrong filter by mistake.

Understanding Mobil 1 filter types

Mobil 1 makes several filter lines for different needs. The standard Mobil 1 filter is designed for regular oil change intervals. Mobil 1 Extended Performance filters are built to last longer and are meant for vehicles that use synthetic oil and longer drain intervals — typically 10,000 miles or more. If your vehicle manual recommends extended-drain service, the Extended Performance filter is the right choice.

Some Mobil 1 filters also come with a bypass valve, which allows oil to flow around the filter if it becomes clogged, preventing engine damage. This is a standard safety feature in most modern filters. The part number will tell you which type you are getting, so stick with the number the finder tool gave you.

Confirming the filter before you install it

When your filter arrives or you pick it up, check the part number on the package against the number you looked up. The filter should also have a gasket — a rubber ring on the top — that seals it to the engine. Make sure the gasket is present and not damaged before you install the filter.

If you are installing the filter yourself, hand-tighten it until the gasket contacts the engine, then turn it an additional three-quarter turn. Do not use a wrench to tighten it — hand-tight is correct. Over-tightening can damage the gasket and make the filter difficult to remove next time.

Keeping track of your filter information

Once you know your Mobil 1 filter part number, write it down or save it in your phone. Keep this information with your vehicle documents or in a notes app. When you need a replacement, you can order it when ready without having to look up your vehicle details again. Many people also note the date they installed the filter so they know when the next change is due.

If you take your vehicle to a service shop for oil changes, you can tell the technician you want a Mobil 1 filter and provide the part number. This ensures you get the correct filter and the exact brand you prefer.

Frequently Asked Questions

Can I use a Mobil 1 filter if my vehicle manual does not mention it?

Yes. Mobil 1 filters meet or exceed the standards required by vehicle manufacturers. As long as the part number matches your vehicle, the filter will work correctly. The brand does not matter — what matters is that the filter is designed for your specific engine.

What if the Mobil filter finder tool shows no results for my vehicle?

This usually means your vehicle is very old or very new and Mobil may not make a filter for it yet. Call Mobil's customer service line or visit an auto parts store and ask staff to cross-reference your vehicle. They can often find a compatible filter from another brand or tell you if Mobil makes one under a different part number.

Is a Mobil 1 Extended Performance filter worth the extra cost?

It depends on your vehicle and driving habits. If your manual recommends synthetic oil and longer drain intervals, the Extended Performance filter is designed for that use and is worth buying. If you use conventional oil and change it every 3,000 to 5,000 miles, the standard Mobil 1 filter is sufficient and will cost less.

Can I install a Mobil 1 filter myself, or do I need a technician?

You can install it yourself if you have basic tools and a safe place to work. You will need an oil filter wrench, a drain pan, and a jack and jack stands if you need to get under the vehicle. If you are not comfortable working under a car, a technician can install it quickly and inexpensively.
