Finding your ACDelco oil filter starts with your vehicle's year, make, and model

ACDelco, General Motors' parts brand, makes oil filters for GM vehicles and some others. To find the correct filter, you need three pieces of information: your car's year, the make (Chevrolet, GMC, Cadillac, Buick, or another brand), and the model name. Once you have those, you can look up the filter number through ACDelco's website, a parts retailer, or your owner's manual.

The filter number matters because oil filters come in different sizes and thread types. Using the wrong filter can mean it doesn't seal properly, leaks, or doesn't fit at all. The right filter ensures oil flows correctly through your engine and traps contaminants the way it should.

Key Takeaways

  • ACDelco's official website has a parts finder tool where you enter your vehicle details and see the correct filter part number.
  • Your owner's manual lists the filter specification in the maintenance section, usually near the oil capacity information.
  • Auto parts retailers like AutoZone, O'Reilly, and NAPA can look up the filter by year, make, and model at no charge.
  • The filter part number tells you the size and thread pitch, so writing it down before you shop prevents buying the wrong one.

Using ACDelco's official parts finder

ACDelco's website includes a parts lookup tool at acdelco.com. Click on "Find Parts" or "Parts Finder" and select your vehicle year, make, and model from dropdown menus. The tool then displays all ACDelco parts available for your vehicle, organized by category. Navigate to "Filters" or "Engine Maintenance" to see the oil filter options.

The tool shows you the part number, a brief description, and sometimes the price. Write down the full part number — it typically looks like PF63 or PF1218 — before you leave the website. This number is what you'll give to a parts counter or use to search at an online retailer.

Checking your owner's manual

Your vehicle's owner's manual contains the factory oil filter specification in the maintenance or service section. Look for a page titled "Maintenance Schedule," "Fluid Capacities," or "Recommended Fluids and Capacities." The oil filter information is usually listed alongside the oil type and capacity.

The manual may list the filter by ACDelco part number, or it may describe it as a spin-on filter with a specific micron rating and thread size. Either way, this is the authoritative source for what your vehicle needs. If you've lost your physical manual, you can often find a PDF version by searching "[your year, make, model] owner's manual" online.

Looking up the filter at a parts retailer

AutoZone, O'Reilly Auto Parts, NAPA, and Advance Auto Parts all have online lookup tools. Go to their website, enter your vehicle year, make, and model, and search for "oil filter." The site will show you available options, usually including ACDelco filters alongside other brands. Each listing includes the part number and price.

You can also call or visit a store in person. Give the counter staff your vehicle information, and they'll tell you the correct ACDelco filter number and whether they have it in stock. Many retailers offer same-day pickup if you order online, which can be faster than waiting for shipping.

Understanding what the part number tells you

ACDelco oil filter part numbers follow a pattern that describes the filter's size and thread type. For example, PF63 is a common filter for many Chevrolet and GMC trucks, while PF1218 fits different engines. The letters and numbers are not random — they're a code that tells mechanics and parts people the filter's dimensions and compatibility.

This is why writing down the exact part number matters. If you search for "ACDelco oil filter" without a number, you'll see dozens of results. With the number, you get the one filter that fits your vehicle. If a retailer tells you they don't have that specific number in stock, they can usually order it or suggest when it will arrive.

What to do if you can't find your vehicle information

If you don't know your vehicle's year, make, or model, check your vehicle registration, insurance card, or the door jamb sticker on the driver's side. The sticker shows the year, make, model, and sometimes the engine size. Your VIN (vehicle identification number) also contains this information — it's on your registration and visible on the dashboard at the base of the windshield.

If you have the VIN but not the other details, you can use a free VIN decoder online to pull out the year, make, and model. Once you have those three pieces of information, you're ready to look up the filter using any of the methods above.

Comparing ACDelco filters to other brands

ACDelco makes filters in different quality levels. The PF series is their standard line, while the ACDelco Professional line offers extended drain intervals on some models. Both are designed to work with your vehicle, but they may have different prices and recommended oil change intervals.

Some people choose non-ACDelco filters because they cost less. Any filter you buy should meet your vehicle manufacturer's specifications — the part number lookup ensures this. If you're unsure whether a different brand will work, ask the parts retailer to confirm it has the same thread size and micron rating as the ACDelco filter your manual recommends.

Frequently Asked Questions

Can I use an ACDelco filter in a non-GM vehicle?

ACDelco makes filters for some non-GM cars, but most of their lineup is designed for Chevrolet, GMC, Cadillac, and Buick vehicles. Check the parts finder or ask a retailer whether an ACDelco filter is available for your specific vehicle. If not, you'll need a filter from another manufacturer.

What if the part number I find online doesn't match my manual?

This can happen if your manual is older or if ACDelco has updated the part number. Call an ACDelco dealer or a parts retailer with both numbers and ask if they're interchangeable. Usually they are, but it's worth confirming before you buy.

Do I need to buy the filter from an ACDelco dealer?

No. ACDelco filters are sold at most auto parts retailers, online marketplaces, and dealerships. Prices and availability vary by location and retailer, so comparing a few sources can save you money.

What does the micron rating on an oil filter mean?

The micron rating describes how small the particles the filter can trap are. A lower number means finer filtration. Your vehicle's manual specifies the correct rating for your engine. Using a filter with a different rating can affect engine protection or oil flow.
