Routine oil changes keep your 2015 Honda CRF250L running at peak performance and extend engine life. This comprehensive guide covers every step required to perform an oil and filter change on your CRF250L, including specific tips and precautions for this model year.
Tools and Materials Needed
- 8mm and 12mm sockets (preferably deep well)
- Ratchet
- Torque wrench (recommended, not required)
- Allen key (if your skid plate requires it)
- 1.6 quarts (1.5 liters) 10W-30 or 10W-40 motorcycle oil (Honda GN4 or equivalent)
- New OEM or high-quality oil filter
- New crush washer for the drain bolt
- Oil filter cover gasket (recommended, but can be reused a couple of times)
- Oil drain pan
- Paper towels or rags
- Contact cleaner (optional, for cleaning surfaces)
- Funnel (optional, but highly recommended)
- Gloves and safety glasses (for safety)
Preparation and Important Model-Specific Notes
- Honda recommends oil and filter changes every 8,000 miles or 12 months, whichever comes first. More frequent changes are advised for harsh riding conditions.
- If you have an aftermarket skid plate, it's best to remove it to avoid spilled oil pooling and making a mess—even if there's a cutout for the oil drain bolt.
- In cold climates or cold starts, warm up the engine by idling for 3-5 minutes before draining the oil to allow better drainage and suspend particulates.
- Stock oil is 10W-30; you may use 10W-40 in hotter climates.
- Always replace the crush washer and oil filter cover gasket as recommended by Honda to ensure there are no leaks. If reusing, inspect closely for wear or damage.
Steps to Change the Oil
-
Warm Up the Engine
Start your CRF250L and let it idle for 3-5 minutes. This helps the oil flow and suspends harmful particulates.
Turn off the engine and let it sit for a minute. -
Remove Skid Plate (if necessary)
If your CRF250L has a skid plate–especially an aftermarket one–use the appropriate Allen key or socket to remove it for easier access and to prevent oil from pooling in the plate.
Some plates have cutouts, but oil may still collect around the edges. -
Remove the Oil Fill Cap
Unscrew the oil fill cap on the right side of the engine. This prevents a vacuum when draining oil and allows for a faster drain.
Wipe the area with a rag to prevent debris from entering the engine. -
Drain the Old Oil
Place your drain pan directly under the oil drain bolt at the bottom of the engine case.
Use a 12mm socket and ratchet to remove the drain bolt and crush washer. Allow all oil to fully drain.
Inspect the old oil for signs of contamination or metal particles.
Use a rag to clean the area around the oil drain. -
Remove and Replace the Oil Filter
With an 8mm socket, remove the bolts securing the oil filter cover on the right side of the engine.
Gently remove the cover—be mindful of residual oil.
Remove the old oil filter.
Inspect or replace the oil filter cover gasket as necessary.
Insert the new oil filter, ensuring the correct orientation (follow the arrows or instructions in your manual). -
Reinstall Oil Filter Cover
Reattach the oil filter cover and hand-tighten the bolts, then torque them evenly to 9 foot-pounds (12 Nm) using a torque wrench.
Confirm that the gasket sits properly and isn't pinched. -
Reinstall Drain Plug
Install a new crush washer on the oil drain bolt.
Thread the bolt by hand, then torque it to specification (usually around 18 foot-pounds (24 Nm)–check your manual for exact figure).
Wipe away any oil residue. -
Add New Oil
With the filler cap removed, pour in 1.6 quarts (1.5 liters) of 10W-30 or 10W-40 motorcycle oil.
Use a funnel to avoid spills.
Replace the oil fill cap. -
Check Oil Level and Leaks
Start the engine and let it idle for a few minutes; check the area around the drain plug and oil filter for leaks.
Shut down the engine and let it sit for 2-3 minutes.
Park the bike upright (not on the sidestand) and check the oil level using the sight glass or dipstick. Add oil as needed. -
Reinstall Skid Plate and Clean Up
Reattach the skid plate if removed.
Dispose of old oil and the filter properly at a recycling center.
Wipe down the engine and check one more time for leaks.
