The 2010 Cadillac CTS uses different oil filters depending on the engine, so the exact part number isn’t universal for the model year. In most cases you’ll need an OEM GM oil filter from the ACDelco line, selected to match your CTS engine: 3.0-liter V6 or 3.6-liter V6. Check your engine code to confirm the correct filter.
Two engine options offered in the 2010 CTS
The 2010 CTS was available with two gasoline engines. Each engine type uses a different oil filter specification, so identifying the correct engine is the first step toward selecting the right filter.
3.0-liter V6
For the 3.0L V6 variant, use an ACDelco oil filter that is specified for GM’s 3.0L V6 family. The exact part number depends on the specific engine variant and production details; verify with GM’s parts catalog or by checking the existing filter.
3.6-liter V6
For the 3.6L V6 variant, use an ACDelco oil filter matched to GM’s 3.6L V6 family. As with the 3.0L, the exact part number varies by engine code, so confirm via the GM parts catalog or the current filter on the vehicle.
How to verify the exact part number
The most reliable way to confirm the correct oil filter for your specific CTS is to verify the engine code or VIN, then cross-check with GM’s official parts catalog or your dealer. You can also remove the existing filter and read the part number printed on it, then order that exact number or a confirmed equivalent.
Option A: Look up the VIN in the GM Parts Documentation or at a dealer parts desk to pull the correct filter number for your exact vehicle configuration.
Option B: Remove the current filter and note the part number printed on the can; use that to cross-reference with a reputable parts retailer.
Option C: Use a reputable auto parts site and filter by engine code (3.0L V6 or 3.6L V6) and model year to verify compatibility with the 2010 CTS.
In all cases, using the correct filter for your engine ensures proper sealing, flow, and filtration performance. If you’re unsure, a dealer or trusted mechanic can confirm the right part number for your specific CTS.
Summary
For a 2010 Cadillac CTS, the oil filter depends on the engine: 3.0L V6 or 3.6L V6. The best practice is to identify the engine code via VIN, consult the GM/ACDelco parts catalog, or check the existing filter’s markings to determine the exact part number. Use an OEM or equivalent high-quality filter that matches GM’s specifications for your engine to maintain proper lubrication and protection.
