Finding your AC Delco filter starts with your vehicle's year, make, and model

AC Delco makes oil filters for most General Motors vehicles and many others. To find the correct filter, you need three pieces of information: your car's year, the make (like Chevrolet or GMC), and the model (like Silverado or Equinox). You can find these on your vehicle registration, insurance card, or the driver's side door jamb. Once you have this information, you can look up the right filter number using AC Delco's online tool or by asking a parts retailer.

The filter number matters because using the wrong size or type can affect how well your engine is protected. An undersized filter may not catch all the dirt in your oil, and an oversized one might not fit in the engine bay. AC Delco filters are designed to work with specific engine sizes and oil capacities, so matching the number to your vehicle is the first step.

Key Takeaways

  • You need your vehicle's year, make, and model to find the correct AC Delco filter number.
  • AC Delco's website has a lookup tool where you enter your vehicle information and see the matching filter part number.
  • Auto parts stores like AutoZone, O'Reilly, and NAPA can also look up the right filter if you give them your vehicle details.
  • The filter part number is printed on the filter itself, so if you have an old filter from your car, you can match it to find a replacement.

Using AC Delco's online lookup tool

AC Delco's website has a parts finder at acdelco.com. Go to the site and look for the "Parts Finder" or "Find Parts" section. You will enter your vehicle's year, make, and model into the search box. The tool will show you a list of parts that fit your vehicle, including oil filters.

Once you see the filter options, the tool displays the part number, a brief description of the filter type, and sometimes the price range. Write down the part number — it usually starts with "PF" followed by numbers, like PF1218. This number is what you will use when you order the filter online or ask for it at a store.

If the lookup tool does not load or you have trouble navigating it, you can also call AC Delco's customer service line. They can look up the filter for you over the phone if you provide your vehicle information.

Getting the filter number from an auto parts store

If you do not want to search online, walk into any major auto parts retailer with your vehicle's year, make, and model written down. Stores like AutoZone, O'Reilly Auto Parts, NAPA Auto Parts, and Advance Auto Parts all carry AC Delco filters and have computer systems that can look up the right one for you.

Tell the employee your vehicle information, and they will search their system and show you the AC Delco filter that matches. Many stores will also show you filters from other brands at different price points so you can compare. The employee can tell you whether the filter is in stock and can order it if it is not.

Some stores offer to install the filter for you if you buy it there, though there is usually a small labor charge. This can be faster than doing it yourself if you do not have the tools or workspace.

Matching your old filter to find a replacement

If you have the old filter from your last oil change, you can use it to find a replacement without looking up your vehicle information. The part number is printed on the filter's label or stamped into the metal canister. Look for a number that starts with "PF" — that is the AC Delco part number.

Once you have the number, you can search for it online, call a parts store, or go in person and ask for that exact part number. This method works well if you know your filter has worked in your car before and you just want the same one again.

Keep in mind that if you have changed your engine or done major work on your vehicle since the last filter, the old filter number might not be correct anymore. If you are unsure, use your vehicle's current year, make, and model to look up the filter instead.

Understanding AC Delco filter types and part numbers

AC Delco makes several types of oil filters, and the part number tells you which type you are looking at. Standard AC Delco filters are the basic option and work well for regular oil changes. AC Delco also makes synthetic filters, which are designed to last longer and handle synthetic oils better. Some filters are labeled as "Duramax" or "Duramax Plus," which are made for diesel engines or heavy-duty use.

The part number itself does not tell you the type — you have to read the product description. When you look up your filter online or at a store, the description will say whether it is standard, synthetic, or heavy-duty. Choose the type that matches the oil you use and your vehicle's engine type.

If you are not sure which type to buy, check your owner's manual or ask the parts store employee. They can recommend the right filter based on your vehicle and driving habits.

Where to buy AC Delco oil filters

AC Delco filters are sold at most auto parts stores, including AutoZone, O'Reilly, NAPA, and Advance Auto Parts. They are also available online through Amazon, eBay, and the manufacturers' own websites. Walmart and some grocery stores with automotive sections carry them as well.

Prices vary depending on the filter type and where you buy it. Standard filters usually cost between $8 and $15, while synthetic filters run higher. Online retailers sometimes have lower prices than brick-and-mortar stores, but you have to wait for shipping. If you need the filter right away, a local store is faster.

When you order online, double-check that the part number matches what you looked up. Some websites let you search by vehicle year, make, and model, which reduces the chance of ordering the wrong filter.

Frequently Asked Questions

What if the AC Delco lookup tool shows multiple filters for my vehicle?

Different engine sizes or model years within the same vehicle line may need different filters. Check your owner's manual or the filter description to see which one matches your specific engine. If you are still unsure, call AC Delco customer service or ask a parts store employee to confirm which filter is right for your exact vehicle configuration.

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

AC Delco makes filters for many brands beyond General Motors, including Ford, Chrysler, and imports. The lookup tool will show you if an AC Delco filter fits your vehicle. If the tool does not return results for your car, AC Delco may not make a filter for it, and you would need to use a different brand.

Is the part number the same as the filter size?

No. The part number (like PF1218) is AC Delco's internal code for that specific filter. The size refers to the diameter and height of the filter canister. Both matter — you need the correct part number to may support the filter fits your engine and has the right flow rate for your oil system.

What if I order the wrong filter by mistake?

Most auto parts stores allow returns within a set time frame if the filter is unused and in its original packaging. Keep your receipt and the box. If you ordered online, check the retailer's return policy before opening the package. If you installed the wrong filter, remove it and replace it with the correct one as soon as you can.
