Shop parts for a 2024 Suzuki DR-Z400SM Dirt Bike.

Changing the oil in your 2024 Suzuki DR-Z400SM is essential to keeping your bike running strong. Regular oil changes help maintain engine performance and reliability. The DR-Z400SM, Suzuki’s long-running supermoto, has kept its oil change procedure almost unchanged for years, so most guides for previous models still apply for your 2024.

Tools and Parts Needed

  • Ratchet
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Drain pan
  • Funnel
  • Shop towels or rags
  • Gloves and safety glasses
  • New oil filter (Hiflofiltro HF139 or equivalent)
  • Engine oil: 10W-40 motorcycle oil, SF or SG spec (about 2 quarts)
  • Replacement crush washers (for drain bolts, if needed)
  • Service manual (for reference)

Step-by-Step Oil Change Guide

  • Warm up the Engine:–

    Start the bike and let it idle for a few minutes. Warming the oil helps it flow more easily, ensuring a thorough drain.

  • Remove the Oil Filler Cap/Dipstick:–

    With the bike off, unscrew and remove the oil filler cap/dipstick from the top of the frame. This allows the crankcase to vent and helps oil drain smoothly. Pro tip:– When you check the oil later, don’t screw the dipstick in—just rest it on the threads for an accurate reading.

  • Drain the Engine Oil (Engine Side):–
    • Place your drain pan beneath the engine.
    • Use a 17mm socket to remove the engine drain bolt and its crush washer from the bottom of the crankcase, allowing oil to flow out.
    • Inspect the drain bolt and washer. Replace the washer if it's worn or damaged.
    • After draining, reinstall the bolt and washer, torquing to 15 ft-lbs.
  • Drain the Frame Oil (Frame Side):–
    • Move your oil pan under the lower frame drain point.
    • Use a 12mm socket to remove the frame drain bolt and crush washer. Again, inspect and replace the washer if needed.
    • Allow all remaining oil to drain from the frame.
    • Reinstall the frame drain bolt and washer, torquing to manufacturer specification.
  • Change the Oil Filter:–
    • Locate the oil filter cover on the right side of the engine (held on with three 8mm bolts).
    • Remove the bolts, then carefully remove the cover and old oil filter.
    • Clean the filter cover and mating surfaces. Lightly oil the gasket on your new filter.
    • Press in the new filter, making sure it seats correctly. Reinstall the cover and snug down the bolts by hand—do not over-tighten.
  • Optional: Check and Clean the Oil Strainer:–
    • The DR-Z400SM uses an oil strainer. Check your owner’s manual for location; inspect and clean the mesh of debris if needed. This isn’t required every oil change, but is good practice for higher-mileage bikes or if you encounter contaminants.
  • Add Fresh Oil:–
    • Using a funnel, pour in about 2 quarts of quality 10W-40 motorcycle oil that meets Suzuki’s SF or SG standards.
    • Replace the filler cap/dipstick.
    • Start the engine and let it idle for 30 seconds. Shut it off, let oil settle, and check the oil level using the dipstick (do not screw it in when checking). Top off as needed.
  • Dispose of Old Oil Responsibly:–

    Take used oil and the old filter to a recycling center or auto parts store.

  • Final Inspection:–
    • Look for oil leaks around the filter and drain bolts.
    • Double-check oil level once more after a short ride.
