Keep your 2019 Honda CRF250L ABS running at peak performance by following our step-by-step guide to changing the engine oil. Proper oil changes not only extend the engine’s life but also ensure smooth operation on and off the trail. This guide is tailored for the 2019 CRF250L ABS–with specific call-outs and tips unique to this model year.
Tools & Supplies Needed
- 8mm and 12mm sockets (preferably deep well) and a ratchet
- Extension bar (optional, for hard-to-reach bolts)
- Allen key (if you need to remove the skid plate)
- Oil catch pan
- New oil filter (K&N KN-112 or Hiflofiltro HF112 recommended)
- New crush washer for the oil drain plug
- New oil filter gasket
- 1.6 quarts (1.5 liters) of 10W-30 motorcycle oil (check label for JASO MA / API SG or higher, e.g., Pro Honda GN4 or AMSOIL Dirt Bike Oil)
- Paper towels or shop rags
- Torque wrench (recommended for reinstalling the drain bolt)
Step-by-Step Instructions
-
Warm Up the Engine
Start the bike and let it idle for 3-5 minutes. This warms the oil, making it flow out more quickly and evenly when drained. Don’t skip this step, as cold oil will drain more slowly and may leave debris and sludge in the engine.
Tip: Park the bike on a stable, level surface and use a center stand or paddock stand if available. -
Remove the Skid Plate (If Necessary)
If your 2019 CRF250L has an OEM skid plate, it likely has a drain hole for the oil plug, so you might not need to remove it. Aftermarket skid plates may require removal as oil can pool along the side “wings” and create a mess.
Use an Allen key or socket as needed.
Callout for 2019 Model: The OEM configuration is set up for easy oil changes, but always double-check your current skid plate arrangement before you begin.
Be ready with shop towels to catch any stray drips along the plate’s edges. -
Drain the Old Oil
Position the oil catch pan underneath the drain bolt. Using a 12mm socket, carefully loosen and remove the drain bolt located at the bottom of the crankcase.
Let the oil fully drain into the pan—this may take several minutes. Once the oil stops flowing, inspect the old oil for metal shavings or unusual color, which can indicate internal wear.
Remove and replace the crush washer on the drain plug to prevent any leaks. While Honda recommends a new washer each time, the old one can sometimes be reused if undamaged—but for best results, replace it regularly.
Dispose of used oil responsibly at a recycling center or auto parts store. -
Replace the Oil Filter
Locate the oil filter cover (right side of the engine) and remove the bolts with an 8mm socket.
Remove the old oil filter, noting the orientation for the new filter (open side in, rubber gasket out).
Replace the oil filter gasket if needed. While gaskets can be reused a few times, new ones offer the best seal.
2019 CRF250L Specifics: Compatible filter part numbers include K&N KN-112 and Hiflofiltro HF112, both of which are reliable for this engine and oil system.
Lightly oil the new gasket to ensure a proper seal before installing.
Reinstall the filter cover, tightening the bolts evenly. -
Install the Drain Plug
Once all oil has drained, reinstall the cleaned drain bolt with new crush washer.
Torque spec: Tighten to 24 Nm (18 lb-ft) using a torque wrench. Overtightening can strip the threads; undertightening may cause leaks. -
Refill with Fresh Oil
Remove the oil fill cap on the right side of the engine and pour in 1.6 quarts (about 1.5 liters) of 10W-30 motorcycle oil.
Pour slowly and check the window (or dipstick if equipped) to monitor the level.
Replace the fill cap securely after filling. -
Start and Inspect
Start the engine and let it idle for 1 minute. Check for leaks at the drain bolt and around the oil filter cover.
Shut off the engine, allow oil to settle for a couple of minutes, then check the oil level again. Top off as necessary. -
Dispose of Waste Properly
Recycle used oil and the old oil filter at your nearest approved collection center or local shop.
