The typical oil filter for a 2009 Sentra is the Nissan cartridge-type filter, commonly Nissan part number 15208-AX00A (with later revisions such as 15208-AX00B). Always confirm the exact part using your engine code (MR20DE or MR18DE) and your VIN before purchase.
In 2009, the Sentra was offered with more than one four‑cylinder engine, so the filter you need can depend on whether your car uses the 2.0-liter MR20DE or the 1.8-liter MR18DE. Both engines use cartridge-style oil filters, and the replacement should occur with every oil change. The following guide outlines which engines were available, how to identify the correct filter, and practical steps for replacement.
Engine options and filter basics
Two four‑cylinder engines were commonly found in the 2009 Sentra, and both use cartridge-style oil filters. Here’s how to match the right filter to your car:
- 2.0L MR20DE engine: Typically uses Nissan’s cartridge oil filter in the 15208-AX00A family (some catalogs list 15208-AX00B as an updated revision).
- 1.8L MR18DE engine: Uses a cartridge filter in the same general family; exact part should be verified by engine code or VIN to account for catalog revisions.
Because catalogs can vary by region and production year, it’s important to confirm the exact filter against the engine code printed in your owner's manual or on the underhood label. If you’re buying aftermarket, many brands list fitment for the Sentra’s 2.0L and 1.8L engines, but you should double‑check the model number to ensure proper thread size and O‑ring diameter.
Where to find the right filter and cross-references
To locate the precise part, use both your engine code and your VIN, and consider reliable cross-reference options when shopping aftermarket parts:
- Check the vehicle’s owner’s manual or under-hood stamp for the recommended filter part number or engine code.
- Provide the VIN to a parts retailer or Nissan dealer to confirm the exact filter number for your vehicle year and market.
- Common aftermarket brands that are compatible with the Sentra’s 2.0L MR20DE and 1.8L MR18DE include Wix, Bosch, Mann, Mahle, Fram, and Purolator; always verify the specific model number to ensure correct fitment.
Conclusion: Rely on your engine code and VIN to pick the correct filter. The baseline OEM option for many 2009 Sentras is 15208-AX00A, with possible revisions; aftermarket options can be suitable as long as they are confirmed to fit your exact engine and year.
How to replace the oil filter on a 2009 Sentra
Replacing the oil filter is a straightforward maintenance task when you follow proper precautions. The steps below assume you are performing an oil change as well; adapt if you’re only swapping the filter.
- Warm up the engine briefly, then park on a level surface and engage the parking brake. Gather your new filter, the correct type and amount of oil, a new drain plug gasket if applicable, an oil filter wrench (if needed), and a drain pan.
- Drain the oil by removing the oil drain plug and letting the old oil flow into the pan. Replace the drain plug gasket and torque to spec.
- Locate the oil filter housing (cartridge style) on the engine block. Remove the old filter cartridge, taking care not to spill oil.
- Lubricate the O‑ring or seal on the new filter with a small amount of fresh oil, then install the new cartridge filter according to the manufacturer’s instructions. Reassemble the housing or cap and tighten to the specified torque.
- Refill the engine with the recommended oil type and quantity for your engine (e.g., 5W-30 or the grade specified in your manual). Run the engine, check for leaks, and recheck the oil level.
Note: Some 2009 Sentra models in certain markets use a slightly different filter housing or threading. If you encounter resistance or a misfit, double‑check the exact filter part number against your VIN and engine code before forcing a fit.
Summary
For a 2009 Nissan Sentra, the standard oil filter is the Nissan cartridge filter, commonly 15208-AX00A, with potential revision 15208-AX00B. The exact part depends on whether your car uses the 2.0L MR20DE or the 1.8L MR18DE engine, so always verify with your VIN or engine code. Aftermarket filters can work well, but confirm fitment for your specific engine and year. When in doubt, consult a Nissan dealer or trusted parts retailer with your VIN to ensure you buy the correct filter.
