AC Delco Oil Filter Lookup: The Complete Guide to Finding the Exact Right Filter for Your Vehicle​

2026-01-06

Finding the correct AC Delco oil filter for your car, truck, or SUV is a straightforward process when you know where and how to look. The most reliable method is to use the official lookup tools provided by AC Delco and its authorized retailers, which cross-reference your vehicle's specific make, model, year, and engine details with the precise part number required. This guide will walk you through every step, platform, and alternative method to ensure you get the exact filter designed for your engine's protection.

Why the Correct Oil Filter is Non-Negotiable
An oil filter is a critical component of your vehicle's engine system. Its sole job is to remove contaminants—such as metal particles, dirt, soot, and sludge—from the engine oil before it circulates through sensitive bearing surfaces and components. Using an incorrect filter can lead to a range of problems. A filter that is too small or has the wrong thread specification may not seal properly, causing leaks or, in severe cases, a complete loss of oil pressure. A filter with inadequate media or a faulty bypass valve can allow dirty oil to circulate or restrict oil flow, leading to accelerated engine wear and potential failure. Therefore, the lookup process is not just about convenience; it is a fundamental step in performing proper vehicle maintenance.

Understanding the AC Delco Brand and Filter Lines
AC Delco is a genuine General Motors original equipment (OE) parts brand, but its products are designed, engineered, and tested to meet or exceed specifications for a wide range of vehicle makes. Many people do not realize that AC Delco supplies filters for numerous non-GM vehicles. The brand offers several tiers of oil filters to suit different needs and budgets:

  • ACDelco Gold (Professional):​​ This is the premium line, often featuring synthetic filter media for high efficiency, a robust design for durability, and anti-drain back valves to prevent dry starts. It is engineered for extended performance.
  • ACDelco Silver:​​ A standard, high-quality filter designed for standard service intervals and reliable performance in everyday driving conditions.
  • ACDelco Classic (Baseline):​​ An economically priced filter that provides dependable filtration for older vehicles or those with less demanding service needs.

Knowing which line is recommended for your vehicle is part of the lookup process, as the tools will often specify the appropriate tier.

Primary Method: Using Official Online Lookup Tools
The digital age has made part finding incredibly efficient. Several authoritative online tools are connected to massive, regularly updated vehicle compatibility databases.

  1. The Official ACDelco Parts Catalog Website:​​ This is the most authoritative source. Navigate to the ACDelco parts catalog site. You will find a clear "Part Finder" or "Look Up Parts" section. Enter your vehicle information—typically starting with the Year, Make, Model, and Engine displacement. The system will then display all compatible AC Delco oil filters, showing the specific part number (e.g., PF63E), a description, and which product line it belongs to (Gold, Silver, etc.). ​Always double-check that the engine size listed matches your vehicle's VIN plate or owner's manual.​

  2. Major Automotive Retailer Websites:​​ Websites like AutoZone, Advance Auto Parts, O'Reilly Auto Parts, and RockAuto have highly sophisticated vehicle lookup systems. Simply navigate to their oil filter section, input your vehicle details, and filter the results by brand to "ACDelco." These sites are excellent because they will show you all compatible options, prices, and local inventory availability. They serve as a fantastic cross-reference to the official AC Delco catalog.

  3. General Search Engine Query:​​ A simple search like "AC Delco oil filter for [Year] [Make] [Model] [Engine]" can yield quick results from retailer pages. However, use this as a starting point and always verify the part number on a retailer or manufacturer site before purchasing.

Secondary Method: Using Your Existing Oil Filter Part Number
If you are replacing an existing AC Delco filter, the easiest lookup is already in your hand. The part number is stamped directly onto the metal casing of the filter. It will be a combination of letters and numbers, such as ​PF48​ or ​PF63E. You can take this number and:

  • Enter it into the search bar of any major auto parts website.
  • Search for it on the AC Delco catalog site.
    This direct part number search will instantly confirm the filter's specifications and show you all vehicles it fits. This method is foolproof for getting an identical replacement.

Understanding AC Delco Oil Filter Part Numbers
Decoding the part number can provide insights. While not necessary for a basic lookup, it can be helpful. AC Delco part numbers often follow a pattern where "PF" stands for "Passenger Car Filter." The numbers and letters that follow designate specific thread sizes, gasket dimensions, bypass valve pressures, and anti-drain back valve configurations. For example, a ​PF63​ and a ​PF63E​ are very similar but may have a minor specification difference important for certain engine models. ​Never assume a filter with a visually similar number is compatible; always verify using your vehicle's details.​

Manual Lookup: Using Printed Catalogs and Store Assistance
While less common today, printed part catalogs still exist at many professional auto parts stores. The process is the same: locate the section for your vehicle's make, find your model and engine, and the cross-reference table will list the corresponding AC Delco part number. Furthermore, the staff at auto parts stores are trained to use electronic catalogs. You can provide them with your vehicle information, and they can perform the lookup for you, often providing a printout or showing you the exact filter on the shelf.

Information You Need for an Accurate Lookup
To ensure a 100% accurate result, gather this information before you start:

  • Vehicle Year, Make, and Model:​​ This is the absolute minimum (e.g., 2018 Ford F-150).
  • Engine Size and Configuration:​​ This is critical. For instance, a 2018 Ford F-150 could have a 2.7L V6, 3.5L V6, or a 5.0L V8. The correct filter depends on this. You can find this information under the hood on the engine, in your owner's manual, or on your vehicle's registration/VIN plate.
  • VIN (Vehicle Identification Number):​​ For the most precise result, especially on newer or specialty vehicles, using your full 17-character VIN in a professional parts lookup system is the gold standard. It eliminates all ambiguity about factory-installed equipment.

Troubleshooting Common Lookup Issues
Sometimes, you may encounter problems or confusing results.

  • Multiple Results Appear:​​ It is common to see both a "Silver" and a "Gold" filter listed for your vehicle. This simply means both tiers are compatible. Your choice depends on your performance needs and budget. The Gold (Professional) filter typically offers higher capacity and efficiency.
  • ​"No Results Found" Message:​​ First, triple-check that you entered the vehicle data correctly. If correct, it might mean that AC Delco does not have a specific filter listing for that particular vehicle in the database you are using. Try another retailer's website or contact AC Delco customer service. In rare cases for very old or obscure vehicles, you may need to use physical measurements (thread size, gasket outer diameter, height) to find a match.
  • The Part Number Has Been Discontinued or Superseded:​​ Automotive parts are regularly updated. An old part number (e.g., PF46) may have been replaced by a new, improved number (e.g., PF48). A good lookup tool or a knowledgeable parts specialist will identify the correct replacement. ​This is why looking up by vehicle is often safer than relying on an old part number from memory.​

Where to Purchase After Your Lookup
Once you have your confirmed part number, you have several reliable purchasing options:

  • Local Auto Parts Stores:​​ AutoZone, Advance Auto Parts, O'Reilly, NAPA. Benefits include immediate availability and the ability to physically inspect the part.
  • Online Marketplaces:​​ Amazon, eBay. ​Exercise caution here. Only purchase from reputable sellers with high ratings to avoid counterfeit products.​​ Check that the part number in the listing title and description matches exactly.
  • Mass Merchandisers:​​ Walmart, Target. They often carry common AC Delco filters at competitive prices.
  • Direct from Automotive Service Centers:​​ Many dealerships and independent mechanics use and sell AC Delco filters.

Final Verification and Installation Tips
Before you install the filter, perform a final visual check. Compare the new filter with the old one. While designs may update, key features like the threading pattern and gasket size should align. Ensure the rubber gasket on the new filter is lightly coated with fresh oil before installation to ensure a proper seal. Tighten according to the manufacturer's instructions—usually hand-tight plus a quarter to half turn—never overtighten.

By following this structured lookup process, you move from guessing to knowing. You ensure that the AC Delco oil filter you install is the one specifically validated for your engine, providing the protection and performance it was designed to deliver. Consistent use of the correct filter, along with regular oil changes, is one of the simplest and most effective ways to promote long-term engine health and reliability.
