Maintaining your 2012 Honda CRF50F with routine oil changes is critical to engine longevity and smooth performance. This guide—exclusive to MotoSport.com—covers the complete oil change process, outlines the specific tools required, and highlights key model-specific notes every CRF50F owner should know.

Tools and Supplies Needed

  • 10W-40 motorcycle oil (approx. 0.6 liters or 0.6 US quarts; see manual for temperature-specific viscosity)
  • Socket wrench or box-end wrench (17mm for the drain bolt)
  • Drain pan
  • New sealing washer for the drain bolt (recommended for every change)
  • Measuring cup (graduated in milliliters/ounces)
  • Cleaning rag
  • Funnel (optional, for less mess)
  • Nitrile or mechanic gloves (to protect your hands)

Preparation

  • Run the engine for 3–5 minutes to warm the oil. Warm oil drains more thoroughly, carrying out more contaminants.
  • Shut off the engine and wait a couple of minutes for the oil to settle.
  • Always perform an oil change with the bike on a firm, level surface, and upright—either on its center stand or with assistance holding the handlebars.
  • Warning: Engine and oil will be hot. Be careful not to burn yourself.

Step-by-Step Oil Change Guide

  1. Remove the Oil Filler Cap/Dipstick
    Twist out the oil filler cap/dipstick from the right side of the engine, setting it aside on a clean surface. This allows air in, helping oil flow out during draining.
  2. Position the Drain Pan
    Slide your drain pan beneath the crankcase. Make sure it–s centered to catch all the draining oil.
  3. Remove the Drain Bolt
    Use a 17mm socket or wrench to loosen (counter-clockwise) and remove the drain bolt on the bottom-right side of the engine. Remove the old sealing washer (this sits between the bolt head and casing).
  4. Drain the Old Oil Completely
    Let the oil drain until there–s only an occasional drip. To aid draining, gently tilt the bike from side to side (ensure safety and balance). Wipe up any drips with a rag.
  5. Install a New Sealing Washer and Replace the Drain Bolt
    Fit a new sealing washer onto the drain bolt. Reinstall the bolt by hand to avoid cross-threading, then tighten with the wrench. Use a torque wrench to tighten to 18 lbf·ft (24 N·m, 2.5 kgf·m) if available for best results (overtightening may strip the threads or cause leakage).
  6. Add New Oil
    Insert a funnel into the oil fill hole. Pour in approximately 0.6 liters (600 milliliters or 0.6 US quarts) of 10W-40 four-stroke motorcycle oil. Check your dipstick after adding about 500 ml–add oil as needed until the oil reaches the "full" line.
  7. Replace the Oil Filler Cap/Dipstick
    Securely tighten the cap/dipstick. Do not overtighten.
  8. Run the Engine & Re-Check Oil Level
    Start the engine and let it idle for 3–5 minutes to circulate the fresh oil. Shut off the engine, allow the oil to settle for 2–3 minutes, then hold the motorcycle upright and check the oil level again. Add more oil if needed until the level is correct (do not overfill).
  9. Dispose of the Used Oil Properly
    Pour drained oil into a sealed container and take it to a recycling center or collection site—never dispose of oil in the trash or down a drain.

2012 Honda CRF50F Specific Tips

  • This bike does not have an oil filter to replace, just a drain bolt and dipstick.
  • Do not remove the cam chain tensioner push rod bolt—it is near the drain bolt and mistaken removal can cause internal engine issues. Only the oil drain bolt (with a washer) should be removed for draining oil.
  • Honda lists 10W-40 oil as the standard. You may select a different viscosity if you ride in consistently cold or hot climates, referencing the manual‘s recommendations for your area‘s temperatures.
  • Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor – always check the oil level by standing the bike upright, not on the kickstand.
  • If the oil looks milky, grey, or has a burnt odor, this could indicate engine issues or past water ingress—monitor closely and address any abnormalities promptly.

FAQs and Troubleshooting

  • How much oil does it take?
    The 2012 CRF50F takes roughly 0.6 liters (600ml) but always check the dipstick level as slight differences in draining time or leftover oil may change this slightly.
  • Do I have to use Honda brand oil?
    Any high-quality, motorcycle-specific 10W-40 four-stroke oil meeting API service standards is safe. Do not use automotive or non-motorcycle oils.
  • How often should I change the oil?
    Honda calls for regular changes—frequently every 6 months or 600 miles—for best practice, especially with hard or dirty riding environments.
  • My drain bolt‘s sealing washer looks fine, can I reuse it?
    It is always best to install a new washer to prevent leaks, though short-term re-use in an emergency is typically possible if no damage is visible.

Conclusion

Changing the oil on your 2012 Honda CRF50F is a straightforward job—no special tools required and with easy access to the drain and fill points. Using quality oil and following the above steps ensures long engine life.
