Tools and Materials Needed

  • 12mm and 14mm sockets or T-handles
  • Socket wrench
  • Drain pan or oil catch pan
  • Funnel
  • Paper towels or clean rags
  • New oil filter
  • New O-ring for oil filter cap
  • Recommended engine oil: Suzuki PERFORMANCE 4 MOTOR OIL or an equivalent; make sure oil meets API SF/SG/SH/SJ and JASO MA ratings
  • Torque wrench
  • Gloves (optional, but suggested)

Step-by-Step Oil Change Instructions

  • Warm Up the Engine
    • Start your RM-Z250 and let it idle for a few minutes. Warm oil flows more easily, ensuring a thorough drain.
  • Secure the Bike
    • Place the bike on a triangle stand or center stand to keep it upright and stable during the maintenance process.
  • Drain Old Oil
    • Locate the drain plug beneath the engine. Place your oil drain pan directly under the plug.
    • Using a 12mm or 14mm socket, loosen and remove the drain bolt. Let the oil drain completely into the pan.
    • Check for metal shavings or debris in the drained oil–this can be a sign of internal engine wear.
  • Remove Oil Filter
    • Locate the oil filter cap on the right side of the engine case.
    • Remove the bolts securing the oil filter cap.
    • Carefully remove the cap, spring, and old oil filter. Note the filter’s orientation for reinstallation.
  • Install New Oil Filter
    • Lightly oil the new oil filter’s gasket before installation. This helps with sealing and removal at the next service.
    • Install the new oil filter in the same orientation as the old one.
    • Install a new O-ring onto the oil filter cap, lightly coat it with fresh oil, and reinstall the cap with its bolts.
    • Tighten the oil filter cap bolts to the specified torque: 11 N·m (1.1 kgf-m, 8.0 lb-ft).
  • Replace Drain Plug
    • Reinstall the drain bolt and tighten to manufacturer specification. Check the condition of the drain bolt washer and replace if needed.
  • Add New Oil
    • Remove the engine oil fill cap.
    • Place a funnel in the filler hole and add the correct oil volume:
      • Oil change with filter: 950 ml
      • Oil change with new filter: 1,000 ml (1.0 L)
    • Replace and tighten the filler cap.
    • Start the engine and let it idle for a few minutes. Shut off the engine and wait a few more minutes before checking oil level using the sight glass or dipstick.
    • If needed, top off oil to the correct level.
  • Dispose of Used Oil Properly
    • Transfer used oil to a sealed container and dispose of it at an authorized recycling center. Never pour oil down drains or onto the ground.

2014 Suzuki RM-Z250 Specific Call-Outs

  • Oil Volume: With an oil filter change, the engine requires 950 ml to 1,000 ml of oil.
  • Recommended Oil Type: Use Suzuki PERFORMANCE 4 MOTOR OIL, or a high-quality equivalent that meets the required specifications.
  • Change Interval: Suzuki recommends changing the oil every six hours of riding to maintain performance and protect engine longevity.
  • O-Ring Replacement: Always use a new O-ring for the oil filter cap to prevent leaks.
  • Torquing: Use a torque wrench to secure both the drain bolt and oil filter cap bolts. Over-tightening may cause damage; under-tightening risks leaks.
  • Check for Leaks: After the oil change and short test run, inspect around the drain bolt and oil filter cap for any sign of seepage.

Final Tips

  • Because the RM-Z250 is a performance motocrosser and typically run hard, always err on the side of more frequent maintenance if you ride in extreme conditions.
  • Record your maintenance dates and oil change intervals for future reference and to protect your investment.
