Tools and Supplies Needed

  • Ratchet
  • 8mm, 12mm, and 17mm sockets
  • Torque wrench (capable of measuring 15 foot-pounds)
  • Drain pan
  • Funnel
  • Gloves and safety glasses
  • Rags for cleanup
  • Genuine Suzuki oil filter (or equivalent, consult your manual)
  • 10W-40 motorcycle oil (at least 2 quarts)
  • Replacement washers for drain bolts (recommended)
  • Optional: Skid plate removal tool if fitted

Before You Start

  • Start your bike and let it idle for about five minutes. This warms the oil, helping it drain out more completely and bringing dirt and contaminants into suspension for removal.
  • Park the bike upright on a level surface. Use a stand if available for stability.
  • Remove any skid plate if equipped, since it can catch spilled oil.

Step-by-Step Oil Change Procedure

  1. Remove the oil filler cap/dipstick.
    • Locate the filler cap on top of the frame. Removing it now allows air to enter and helps the oil drain faster and more completely.
  2. Drain the engine oil from the crankcase.
    • Place your drain pan under the bottom of the engine.
    • Using your 17mm socket, remove the crankcase drain bolt and washer.
    • Let all oil drain out. Inspect the drain bolt washer and replace if deformed or damaged.
  3. Drain the oil from the frame downtube.
    • Move the drain pan under the lower front of the frame.
    • Use your 12mm socket to remove the frame drain bolt and its washer.
    • Allow oil to finish draining. Again, check the washer and replace if needed.
  4. Remove and replace the oil filter.
    • Locate the oil filter cover on the right side of the engine case.
    • Use the 8mm socket to remove the bolts holding the cover.
    • Remove the cover (some oil will spill, keep the pan beneath).
    • Carefully remove the old filter and clean the filter cavity.
    • Check the O-ring on the cover and replace if cracked or deformed.
    • Install the new filter. Most filters are directional—watch for markings or consult the service manual.
    • Reinstall the cover and torque the bolts to spec (do not overtighten).
  5. Reinstall drain plugs and torque to spec.
    • Install a new or inspected washer on each bolt.
    • Engine drain bolt: Tighten to 15 ft-lbs (consult your manual for confirmation).
    • Frame drain bolt: Tighten to spec (consult manual; recommendations and torque values may vary between production years).
  6. Add fresh oil.
    • Insert a funnel in the frame oil port.
    • Add 1.8 liters (about 1.9 quarts) if replacing the filter, or 1.7 liters (1.8 quarts) for an oil-only change.
    • After filling, reinstall the filler cap/dipstick.
  7. Check for oil leaks and verify the oil level.
    • Start the engine and let it idle for several minutes, then shut off and let stand for a few minutes.
    • Remove the dipstick, wipe it, reinsert fully (do not thread), remove again, and check the oil level.
    • Top-up as needed so the level sits between the minimum and maximum marks.
    • Inspect all around for oil leaks at the drain plugs and filter cover.
  8. Reinstall the skid plate (if removed).
  9. Dispose of used oil and filter responsibly—never pour oil down the drain.

2010 Suzuki DR-Z400SM Model-Specific Callouts

  • This model uses a dry-sump oiling system. Oil circulates between the engine and the frame’s downtube reservoir, so always drain both locations for a complete oil change.
  • Oil capacity: 1.8 liters with filter change; 1.7 liters without filter.
  • Do not overtighten drain bolts. The frame and case threads can be stripped easily. Always use a torque wrench if available.
  • Recommended oil: 10W-40 motorcycle oil, not automotive oil. Synthetic or semi-synthetic are acceptable as long as JASO MA/MA2 rated.
  • Inspect and replace drain plug washers as needed to prevent seeping or leaks.

Pro Tips for a Worry-Free Oil Change

  • Change oil every 3,000–3,500 miles or as specified in your manual. The first change should occur after 600 miles on a new bike.
  • Keep extra washers and filters on hand for convenient future changes.
  • Clean up oil spills promptly—oil can damage paint and attract dirt.
  • Double-check drain plug and filter cover torque after your first short ride, in case of settling or seepage.

Changing the oil on your 2010 Suzuki DR-Z400SM is straightforward and can be completed in under an hour with the right tools and supplies.
