Changing the oil in your 2017 Suzuki DR-Z70 is an essential maintenance task that maximizes engine life, protects the auto-clutch system, and ensures peak performance. This step-by-step guide is tailored for owners of this specific model and includes all critical tools, procedures, and call-outs unique to the DR-Z70 dirt bike.

Tools & Supplies Needed

  • 12mm wrench (socket or combination) – for removing the drain bolt
  • Oil catch pan – to collect the used oil
  • Funnel – for clean oil refilling
  • Measuring cup (marked up to at least 700 milliliters)
  • Fresh motorcycle oil (10W-40, motorcycle-specific, e.g., AMSOIL or Valvoline)
  • Rags or paper towels – for cleanup
  • Optional: gloves, to protect your hands

Step-by-Step Instructions

  1. Warm up the engine (Optional but recommended)
    Briefly start and run the engine for 2-3 minutes to allow the oil to warm up and flow more freely. Do not let the engine get hot—just warm to the touch. Turn off the engine and let it sit until you can safely touch the exhaust.
  2. Stabilize the Dirt Bike
    Park the DR-Z70 on a level surface using the kickstand, or better yet, place it upright on a stand to ensure maximum drainage of old oil.
  3. Locate the Drain Plug and Oil Filler Cap
    The oil drain bolt is on the underside of the engine, typically near the frame’s lowest point. The filler cap/dipstick is on the right side of the engine. Remove the filler cap to help the oil drain smoothly .
  4. Drain the Old Oil
    • Place the oil catch pan directly under the drain plug.
    • Using the 12mm wrench, loosen and remove the drain bolt. Oil will begin to drain; take care not to lose the bolt or its crush washer.
    • Allow all oil to drain out completely. Slightly tipping the bike upright can help drain the last bit.
  5. Inspect and Reinstall the Drain Bolt
    • Check the condition of the drain bolt’s washer. If it appears crushed or damaged, replace it. This is vital for preventing leaks.
    • Wipe down the drain bolt and bolt hole. Start threading the bolt by hand to avoid cross-threading, then tighten with the wrench. Do not overtighten—firm and snug is sufficient.
  6. Measure and Add New Oil
    • Using a clean measuring cup, pour out exactly 700 milliliters (ml) of 10W-40 motorcycle oil. This is the correct fill amount for the 2017 DR-Z70 (do not overfill) .
    • Place the funnel in the oil filler opening and carefully pour in the new oil.
    • Wait a few moments to allow the oil to settle, then check the level with the dipstick to confirm proper fill.
  7. Replace the Filler Cap, Check for Leaks & Run Engine
    • Reinstall the filler cap/dipstick.
    • Start the bike and let it run for a minute.
    • Turn off the engine and inspect around the drain bolt and under the bike for leaks.
    • Check oil level once more after sitting, and top up if needed—only in small increments.
  8. Dispose of Old Oil Properly
    Take your used oil to a certified recycling facility or your local auto parts store.

2017 Suzuki DR-Z70 Model-Specific Notes

  • Always use a motorcycle-specific 10W-40 oil. Oils for cars can harm the DR-Z70’s auto clutch and transmission due to missing friction modifiers .
  • Oil capacity is exactly 700 ml. Overfilling may cause excess crankcase pressure or leaks, while under-filling risks engine and clutch damage .
  • No replaceable oil filter. The DR-Z70 uses a screen-type “filter” inside the engine that is maintenance-free for basic oil changes.
  • Auto clutch system (no clutch lever): Correct oil type is crucial to prevent slipping or wear of the clutch packs.
  • If the bike has been sitting for months/years, consider performing a second oil change after a short ride to clear out pre-existing sludge and contaminants.

Tips for Success & Longevity

  • Change oil every 10 hours of riding or every six months, whichever comes first, as recommended for mini dirt bikes.
  • Inspect the drained oil for metal flakes or gritty particles—these can indicate abnormal engine wear and should prompt further inspection.
  • Keep oil change records to track maintenance for resale value and long-term engine protection.

With these steps, you’ll keep your 2017 Suzuki DR-Z70 running strong and reliable—on the track or the trails. For premium products and more OEM-specific maintenance tips, shop MotoSport.com.
