Shop parts for a 2016 Honda CRF50F Dirt Bike.

Regular oil changes are essential to keep your 2016 Honda CRF50F running reliably and performing at its best. Changing the oil on this model is straightforward and similar across model years, but it’s important to follow the correct procedure and use the right tools and oil.

Tools & Supplies Needed

  • 17mm socket or wrench (for oil drain bolt)
  • Socket wrench
  • Oil drain pan
  • Measuring cup (600 ml or cc capacity)
  • Funnel (optional, for filling)
  • Gloves (to keep your hands clean)
  • Clean rags or paper towels
  • Replacement engine oil: 10W-40 four-stroke motorcycle oil (recommended by Honda, Maxima SynBlend or Honda GN4 are common options)

Step-by-Step Instructions

  1. Warm up the engine:
    • Start the engine and let it idle for about 3–5 minutes. This helps the oil warm up, becoming more fluid and easier to drain.
    • Turn off the engine and allow a moment for the oil to settle.
    • Be careful—the engine parts and oil will be hot.
  2. Position the bike:
    • Place the CRF50F on a level surface. Using a bike stand or jack can make access easier, but ensure it's stable. Some position the front end on a small jack due to the bike’s low height.
  3. Locate the oil drain bolt:
    • The drain bolt is under the engine, typically under a lip at the front of the engine case. Use your 17mm socket or wrench to remove it. Turn counterclockwise (lefty-loosey) to loosen.
    • Have your oil drain pan in place underneath before removing the bolt to catch all old oil.
  4. Drain the oil:
    • Remove the drain plug by hand once loose. Allow all the oil to drain into the pan—this may take several minutes as the oil trickles out.
    • This is a good time to check the condition of the oil: if it’s very dark or contains metal shavings, it may indicate a maintenance issue.
  5. Replace the drain bolt:
    • Wipe off the drain bolt and reinstall it securely with the socket or wrench—do not overtighten.
  6. Remove the oil fill cap:
    • The oil fill cap is located on the right side of the engine. Remove it and set aside.
  7. Add new oil:
    • Pour in fresh 10W-40 motor oil. The recommended capacity is approximately 600 milliliters (ml) for a standard oil change. You can use a measuring cup for accuracy.
    • Some sources mention 600-700ml as a range—always use the dipstick to verify the correct level. The exact amount can vary slightly depending on how much old oil was removed.
    • Insert the dipstick but do not thread it in, just seat it on the threads for an accurate check. Check that the oil level is in the proper range. Add a small amount if necessary—do not overfill.
    • Make sure the bike is upright and level when checking the oil.
  8. Reinstall the oil fill cap and clean up:
    • Replace the fill cap and wipe off any spilled oil. Dispose of used oil properly at a recycling center or auto parts store.
  9. Start the engine and check for leaks:
    • Run the engine for a minute, then switch it off and check for any oil leaks around the drain bolt and fill cap.
    • Recheck the oil level once more and top up if needed.

Model-Specific Notes: 2016 Honda CRF50F

  • The 2016 CRF50F shares an engine design with previous and later years, so instructions are the same for most CRF50F and XR50 models.
  • The oil drain bolt is always located at the bottom-front of the engine, accessed easily with a 17mm socket.
  • No oil filter needs changing on this model; just drain and refill the oil.
  • Do not worry about hitting an exact oil number—just use the dipstick as your ultimate guide for correctness. The bike takes about 600ml, but sometimes a little more if you’re thorough with draining.
  • Always use a high-quality motorcycle oil formulated for wet clutches; avoid car oil or inappropriate types that may cause clutch slippage.

Warnings and Best Practices

  • Protect hot engine parts: The engine and oil may be hot after warming up—use gloves.
  • Don’t overtighten the drain bolt or fill cap to avoid stripping threads.
  • Change oil regularly: Honda recommends changing the oil at least every 1,000 miles or sooner if riding in harsh conditions.
  • Proper oil disposal: Used oil is hazardous. Store it in a sealed container and take it to a recycling center.
