The oil filter size for a 2008 Silverado depends on the engine. The most common thread size across the lineup is 3/4-16, but the exact filter model and length vary by engine (4.3L, 4.8L, 5.3L, or 6.0L).
Engine options in the 2008 Silverado
In 2008, the Silverado offered several gasoline engines and a heavy-duty setup. The oil filter needs can differ between these powerplants, so identifying your exact engine is key before purchase.
- 4.3L V6 (Vortec 4300)
- 4.8L V8 (Vortec 4800)
- 5.3L V8 (Vortec 5300)
- 6.0L V8 (Vortec 6000) in HD 2500/3500 trims
Regardless of the engine, many of these GM engines use a standard 3/4-16 oil filter thread. The physical size of the filter (short vs. long) can vary by engine and application, so always confirm with the exact part number for your model.
How to determine the exact oil filter for your truck
Because the filter size and part number are engine-specific, use these verification steps to ensure you get the right filter the first time.
- Identify your engine code or check the VIN to confirm which engine your truck has.
- Check the current or removed oil filter for a part number or model designation printed on the canister.
- Consult a cross-reference guide or your vehicle’s manual to match that number to the correct oil filter for the 2008 Silverado.
- If in doubt, bring the old filter to a parts counter or use the exact OEM part number from GM’s catalog to ensure compatibility.
Following these steps will help you select the correct filter size and model for your specific engine configuration.
Summary
For a 2008 Chevy Silverado, there isn’t a single universal oil filter size. The engine determines the filter model, with a common thread size of 3/4-16 across many powertrains. To be certain, identify your engine, verify the current filter’s part number, and use a cross-reference or the OEM catalog to pick the correct filter for your truck.
