We'll cover all the required tools, step-by-step instructions, and highlight details unique to this model.

Tools and Supplies Needed

  • 12 mm wrench or socket (to remove the oil drain bolt)
  • Oil catch pan (to collect old oil)
  • Funnel (for adding fresh oil)
  • Measuring cup or beaker (to measure 700 ml of new oil)
  • 10W-40 motorcycle oil (700 ml, specifically formulated for wet-clutch motorcycles)
  • Clean rag or towel
  • Gloves (optional but recommended)

Important Model-Specific Notes for the 2008 Suzuki DR-Z70

  • Oil capacity:– 700ml of 10W-40 motorcycle oil is standard for this model.
  • Drain bolt size:– 12 mm.
  • No separate oil filter to change — this bike uses only a screen.
  • Auto clutch system:– Use only JASO MA-rated motorcycle oil for wet clutches; never use automotive oil or oil additives.
  • Check for leaks after filling and running the engine briefly.

Step-by-Step Instructions

  1. Warm Up the Engine
    • Start the engine and let it idle for 1-2 minutes to warm up the oil. This helps the oil drain more thoroughly.
    • Turn the engine off before beginning the oil change.
  2. Position the Bike and Prepare Your Workspace
    • Put the bike on its side stand on level ground. If available, use a bike stand to keep it upright and stable.
    • Place your oil catch pan directly underneath the engine's drain plug.
  3. Remove the Oil Fill Cap
    • Unscrew the oil fill cap (on top of the engine, usually by the right-side footpeg). This allows air in, helping the oil drain smoothly.
  4. Remove the Drain Plug
    • Locate the 12 mm drain bolt at the lowest point of the engine's underside.
    • Carefully loosen the drain bolt with the 12 mm wrench and remove it by hand, letting the oil flow into the catch pan.
    • Be cautious — the oil may be warm, and your fingers may get oily at this point.
  5. Let the Oil Completely Drain
    • Allow several minutes for all the oil to drain out. If desired, gently tilt the bike upright to help the last of the oil flow out.
  6. Inspect and Reinstall the Drain Bolt
    • Wipe the drain bolt with a rag to remove sludge or metal particles. Inspect the washer for wear; replace it if damaged.
    • Reinstall and hand-tighten the drain bolt, then snug it with your wrench — do not overtighten.
  7. Add New Oil
    • Using your measuring cup, pour exactly 700 milliliters of 10W-40 motorcycle oil into the funnel and into the oil fill opening.
    • Remove the funnel, then reinstall the oil fill cap securely.
  8. Check Oil Level
    • Start the engine, run at idle for 1-2 minutes, then shut it off.
    • Let the oil settle for a minute, then check the oil level per the dipstick (clean, insert, remove, and check level). Add a little more oil if it is below the mark, but do not overfill.
  9. Inspect for Leaks and Clean Up
    • Visually inspect the drain bolt and area around the fill cap for any leaks during and after test running the engine.
    • Dispose of the old oil responsibly at a recycling center or auto parts store.

Additional Tips for the 2008 Suzuki DR-Z70

  • Use only motorcycle-specific oil rated for wet-clutch systems (JASO MA), as this model's auto clutch shares oil with the engine and transmission.
  • Oil changes are recommended every 6 months or 600 miles (check manual for your usage pattern).
  • There is no paper oil filter to change on the DRZ70, just a metal oil screen. Cleaning this is only necessary during major services.
  • Keep the work area clean and avoid introducing dirt into the engine during oil filling or bolt reinstallation.
  • Record your oil change in a maintenance log for your records and resale value.

Changing the oil in your 2008 Suzuki DR-Z70 is a straightforward task that can be completed in about 30 minutes with minimal tools.
