Changing the oil in your 2019 Suzuki DRZ50 is vital for engine longevity and reliable performance. Regular oil changes help keep your dirt bike running smoothly and prevent costly repairs. Below you'll find a step-by-step guide proprietary to MotoSport.com on how to change the oil, including the recommended supplies, specific considerations for the DRZ50, and expert call-outs tailored to this model.

Tools & Supplies Needed

  • 10mm socket or wrench (for drain bolt removal)
  • Oil drain pan
  • Funnel
  • Rags or shop towels
  • Replacement engine oil (recommended viscosity: 10W-40, see note below)
  • New oil drain bolt washer (optional but recommended)
  • Gloves (to keep hands clean)
  • Torque wrench (if available, for correct torque spec on drain bolt)

Recommended Oil Type & Capacity

  • Engine Oil Viscosity: 10W-40 is the most commonly recommended for the DRZ50, but 10W-30 is also suitable depending on climate and preference.
  • Oil Capacity: 0.74 quarts (approximately 0.70 liters). Do not overfill–always refer to the oil level indicator/dipstick for final adjustment.

Step-by-Step Oil Change Instructions

  1. Warm Up the Engine
    • Let your bike idle for 2-3 minutes to warm the oil. This helps the oil drain more completely.
  2. Turn Off the Engine and Secure Bike
    • Place the bike on its center stand or a stable stand to keep it upright and stable.
  3. Prepare Your Work Area
    • Set out your drain pan and all tools within reach. Put on gloves.
  4. Remove the Oil Filler Cap
    • Unscrew the oil filler cap on top of the engine to allow oil to drain freely.
  5. Remove the Drain Bolt
    • Use a 10mm socket or wrench to loosen the drain bolt, located on the lower side of the engine case.
    • Allow the oil to completely drain into the pan. Be patient; wait until the flow has slowed to a drip.
    • Inspect the old drain bolt washer. Replace if damaged or deformed for a proper seal.
  6. Reinstall the Drain Bolt
    • Clean the drain bolt and threading area.
    • Install a new washer, if available, and hand-tighten the bolt back into place.
    • If you have a torque wrench, tighten to manufacturer's spec (consult service manual or your dealer; generally between 7 and 12 ft-lbs for small bikes).
  7. Add New Engine Oil
    • Insert a funnel into the filler hole and pour in up to 0.7 quarts (0.66 liters) of fresh 10W-40 motorcycle oil.
    • Pause and check the level with the dipstick. Do not screw in the dipstick when checking level—just set it in the hole, pull out, and read.
    • Add more oil as needed to bring the level between the low and full marks.
    • Do not overfill–excess oil can damage engine seals and cause leaks.
  8. Replace the Filler Cap
    • Hand-tighten the filler cap securely.
  9. Start and Check for Leaks
    • Start the engine and let it idle for 1-2 minutes.
    • Inspect the area around the drain bolt and oil filter for leaks.
    • Shut off engine and let stand for 2-3 minutes, then re-check oil level and add a small amount if necessary.
  10. Dispose of Old Oil Responsibly
    • Transfer the drained oil to a sealed container and take it to a recycling or disposal center.

DRZ50-Specific Owner Call-Outs

  • Oil capacity is small: Only about 0.74 quarts are required. Overfilling can cause smoking, leaks, or gasket failure. Always use the dipstick properly–set it on the threads, do not screw it in–when checking the level.
  • No oil filter to change: The DRZ50 does not have an external or replaceable oil filter. Oil changes alone are critical to remove contaminants.
  • OEM manual reference: Always double-check with the owner's manual for any torque specs or special instructions as small bikes can have unique procedures or updates. See your DRZ50 manual for the latest details.
  • Use motorcycle-specific oil: Automotive oil may have incorrect friction modifiers; always use 10W-40 or 10W-30 oil designed for wet-clutch motorcycles.

Oil Change Frequency

  • Suzuki recommends frequent oil changes for youth and mini dirt bikes like the DRZ50, especially when ridden hard or in dirty conditions.
  • As a best practice, change the oil every 10-20 hours of operation or at least once a season—whichever comes first.

Summary Tips

  • Do not overfill–always check the oil level with the dipstick resting on the threads, not screwed in.
  • Run the engine briefly to circulate new oil, then double-check oil level.
  • Use only high-quality motorcycle oil with the correct viscosity.
  • Keep a maintenance log to track oil changes and other service items.

By following these MotoSport.com exclusive instructions, you'll help ensure your 2019 Suzuki DRZ50 delivers reliable performance and years of family fun. Happy riding and safe wrenching.
