Who makes GM oil filter?
GM Original Equipment oil filters are produced under contract for General Motors and branded under ACDelco; the specific manufacturing partner can vary by part number and market.
In practice, GM sources OE filters from contract manufacturers around the world, and the packaging commonly features the ACDelco or GM Original Equipment branding. The exact factory or supplier can differ depending on the vehicle model, engine family, and regional sourcing agreements.
Branding, sourcing, and the GM OE model
GM positions its oil filtration products within the GM Original Equipment program, with ACDelco serving as the consumer-facing brand. The actual production occurs at contracted facilities, which GM selects based on quality, capability, and regional supply needs. This arrangement lets GM maintain engineering and quality standards while leveraging specialized filter production capabilities from multiple suppliers.
What is ACDelco?
ACDelco is GM’s global parts division, responsible for both original equipment and aftermarket components. The ACDelco brand covers oil filters, along with a wide range of maintenance parts, and helps ensure compatibility with GM engines while meeting GM specifications over the vehicle’s life cycle.
How to identify the actual maker of a GM oil filter
The following steps help readers determine who manufactured a specific GM oil filter they’ve purchased or found in their vehicle. The guidance focuses on reading packaging, cross-referencing part numbers, and checking official sources.
- Check the packaging for a “Manufactured for General Motors” label and any line naming a supplier or factory. Some GM OE filters list the contract manufacturer in small print.
- Look up the part number in GM’s official parts catalogs or the ACDelco website; current production details or supplier notes may be provided there.
- Inspect the filter can or body for markings such as a brand name, factory code, or country of origin that can point to the contract maker.
- Consult a GM dealer or GM customer support; they can confirm the current supplier for your specific part and market.
Note that supplier assignments can change over time due to corporate sourcing decisions, plant changes, or regional contracts.
Why the maker matters for maintenance and aftermarket choices
Knowing the supplier can help with warranty considerations, perceived quality, and compatibility. GM OE/ACDelco filters are designed to GM specifications, and many aftermarket filters advertise compatibility with GM engines. When choosing an aftermarket option, ensure the filter meets GM’s specifications for your year and engine family to maintain performance and warranty coverage.
Summary
GM’s official oil filters are produced for the GM Original Equipment program and typically carry the ACDelco branding. The actual manufacturing partner is a contract supplier selected by GM, and the responsible factory can vary by model, year, and region. For most drivers, the key takeaway is to use GM OE/ACDelco-branded filters or other parts that meet GM specifications, and to verify the supplier on packaging or through a dealer if needed.
