Changing the oil in your 2024 Suzuki DR-Z400SM is a straightforward task that you can do at home with basic tools. Regular oil changes help maintain high performance, engine longevity, and reliability—key for your riding adventures. This guide, proprietary to MotoSport.com, will walk you through the process step-by-step and call out specific tips unique to the DR-Z400SM model.

Tools & Supplies Needed

  • Ratchet
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench
  • Drain pan
  • Funnel
  • Paper towels or shop rags
  • Gloves and safety glasses

Parts & Fluids Needed

  • 10W-40 motorcycle oil (2 quarts, consult the owner's manual for exact quantity)
  • Hiflofiltro HF139 oil filter (or OEM equivalent)
  • Replacement washers for drain bolts (if needed)

Manufacturer Recommendations

  • Suzuki recommends SAE 10W-40 oil that meets SF or SG specifications.
  • First oil change: 600 miles; subsequent changes every 3,500 miles, or more often if riding in harsh conditions.
  • The DR-Z400SM oil change procedure remains largely unchanged since the model's introduction in 2000, so these instructions apply broadly to all model years, including 2024.

Step-by-Step Oil Change Instructions

Step 1: Preparation

  • Warm up the engine for a few minutes to help the oil flow more easily. Shut off the engine and ensure the bike is stable, preferably on a stand.
  • Remove the oil filler cap/dipstick from the top of the frame. This allows airflow and ensures oil drains smoothly.

Step 2: Drain the Oil (Engine Crankcase)

  • Position your drain pan underneath the engine.
  • Use a 17mm socket to remove the drain bolt and washer from the bottom of the crankcase.
  • Allow the oil to drain completely—this may take a few minutes.
  • Inspect the washer (replace if necessary), reinstall the bolt, and torque it to 15 foot-pounds using your torque wrench.

Step 3: Drain the Oil (Frame)

  • Move your drain pan beneath the lower part of the frame.
  • Remove the 12mm drain bolt and washer from the bottom of the frame.
  • As before, let the oil drain, then inspect and replace the washer if needed.
  • Reinstall the drain bolt and torque to spec.

Step 4: Replace the Oil Filter

  • Locate the oil filter cover–typically mounted on the right side of the engine case.
  • Use an 8mm socket to remove the cover bolts. Be careful, as residual oil may spill.
  • Remove the old oil filter and O-rings, then install the new filter (Hiflofiltro HF139 or equivalent).
  • Check O-rings for damage and replace if necessary.
  • Reinstall the cover and torque the bolts evenly to avoid leaks.

Step 5: Refill with Fresh Oil

  • Place a funnel in the oil filler opening on the frame.
  • Pour in 2 quarts of 10W-40 motorcycle oil, adjusting as necessary based on the sight glass or dipstick.
  • Replace and secure the oil filler cap/dipstick.

Step 6: Final Checks

  • Start the engine and run it for a minute, checking for leaks around the drain bolts and filter cover.
  • Shut off the engine, let it sit a couple of minutes, then recheck the oil level. Top off if needed.
  • Dispose of the old oil and filter properly—never pour oil down the drain or onto the ground.

2024 Suzuki DR-Z400SM Model-Specific Call-Outs

  • The 2024 model shares its oil change procedure and specs with prior years—no unique changes or parts required for this year.
  • Be careful not to overtighten the oil filler cap/dipstick. Cracking the frame's oil filler port can be costly to repair.
  • Monitor the drain bolt washers for wear during every change and replace as needed to prevent leaks.

Pro Tips

  • Always double-check that both drain bolts and the filter cover are secure before adding oil. A loose bolt can cause catastrophic leaks.
  • Use a funnel to avoid spilling oil on the engine or exhaust.
  • Even though most filters and oils are cross-compatible across DR-Z400 models, always reference your owner's manual for exact torque specs and fluid volumes.
  • Keep a maintenance log noting mileage, date, and oil/filter brand for future reference and resale value.
