The correct oil filter number for a 2008 GMC Sierra 2500 depends on which engine your truck uses. If you have the gas-powered 6.0L V8, the filter is different from the Duramax 6.6L diesel. This article explains how to identify the right part number for your exact configuration and how to verify it.
Know your engine variant
Two main engine options were offered for the 2008 GMC Sierra 2500HD. Each engine family uses a different oil filter specification, so the exact part number must be verified for your specific build date and engine code.
Gasoline engine: 6.0L Vortec
If your 2008 Sierra 2500HD runs the 6.0L Vortec gasoline engine, the oil filter will come from a GM/ACDelco filter line designed for that engine family. Use official GM parts catalogs or trusted parts retailers to confirm the exact filter number for your vehicle’s production date and configuration.
Diesel engine: 6.6L Duramax
How to confirm the exact part number
Use these reliable methods to verify the correct oil filter number for your truck:
- Check the vehicle’s owner's manual or maintenance section, which often lists the recommended oil filter part number for your engine.
- Inspect the oil filter itself for any stamped or printed part numbers that you can cross-reference with manufacturer catalogs.
- Use your VIN to look up cross-reference charts from GM/ACDelco, Wix, Bosch, Mahle, or other reputable brands. These charts map your VIN to the exact filter that fits your engine and build date.
- Visit a local parts counter with your VIN and ask for the correct filter for your specific engine code and production month; they can pull the exact number for you.
Following these steps will help you identify the correct oil filter number, minimizing the chance of installing an incompatible filter.
Where to buy and how to verify
Once you have the correct part number, you can purchase from GM Genuine Parts, ACDelco, or reputable aftermarket brands. Always cross-check the part number against your vehicle’s engine type and year to ensure the filter will seal properly and provide the intended filtration performance.
Summary
In short, there isn’t a single oil filter number for all 2008 GMC Sierra 2500 models. The right number depends on whether your truck uses the 6.0L gas engine or the 6.6L Duramax diesel, and sometimes even the production date within the model year. Verify the exact part number via the owner's manual, VIN-based cross-references, or by checking the filter itself, then purchase from a trusted supplier to ensure proper fit and filtration.
