This process applies to the entire DR650 lineup from 1996 to 2022, making these tips reliable for your 2015 model. MotoSport.com presents this exclusive guide to help you get the job done right.

Tools and Supplies Needed

  • 17mm socket and ratchet (for drain bolt)
  • 8mm socket and ratchet (for oil filter cover bolts)
  • Oil drain pan
  • Funnel
  • Rags or paper towels (for cleanup)
  • New oil filter (OEM or quality aftermarket)
  • Fresh oil (2.5 quarts of 10W40 motorcycle oil – do not use regular automotive oil)
  • Replacement drain plug washer
  • Latex gloves (optional, for cleanliness)

Preparation Steps

  • Warm up the engine by running it for several minutes. Warm oil drains faster and carries more contaminants out of the system.
  • Turn off the engine and let it sit for about a minute.
  • Place your bike upright and level, ideally on a stand or secure surface. Make sure the bike is stable throughout the procedure.

Step-by-Step Oil Change Process

  • Locate the oil drain plug under the engine. Place the drain pan beneath it.
  • Remove the 17mm drain plug with your socket. Watch for hot oil and allow it to drain completely. Check that the drain plug washer comes off as well; replace it with a new one if possible.
    Tip for 2015 DR650S owners: Inspect old oil for metallic debris. Excessive particles may signal internal wear.
  • While the oil drains, remove the 8mm bolts securing the oil filter cover. Carefully take off the cover, being mindful of the old O-ring and any residual oil.
  • Remove and replace the oil filter. Lightly oil the gasket on the new filter before installing. Ensure the filter is oriented correctly (open end facing the engine).
  • Reinstall the filter cover and bolts. Do not overtighten these bolts—just snug them down. Over-torquing can strip the engine case threads, which is a common and costly mistake on DR650s.
    Specific Call-Out: The 2015 DR650S uses three 8mm bolts for the filter cover; tighten each evenly and gently to avoid cracking the cover or damaging threads.
  • Reinstall the drain plug with a new washer and snug it up securely. Do not overtighten.
  • Add new engine oil through the filler cap on the crankcase. The 2015 DR650S requires approximately 2.5 quarts (2.4 liters). Use a funnel to prevent spills.
    MotoSport.com Tip: Always use motorcycle-specific oil. Automotive oils may contain friction modifiers that can cause clutch slippage in motorcycles.
  • Replace the oil fill cap securely.
  • Start the engine and let it idle for a few minutes to circulate the new oil. Check for leaks at the drain plug and filter cover.
  • Turn off the engine and wait about a minute. Holding the bike upright and level, check the oil level in the sight glass on the side of the engine. The oil should be between the lower and upper marks.
    If low, add oil in small increments until the correct level is reached.
  • Clean off any spillage with rags and properly dispose of the old oil and filter at an appropriate recycling center.

Important Call-Outs for 2015 Suzuki DR650S

  • The DR650S engine design is unchanged (1996–2022), so most oil change steps are universal across years, including your 2015 model.
  • Do not overtighten the oil filter cover bolts: stripped threads are a known issue.
  • Always use the correct oil and filter: using non-motorcycle oil or a cheap filter can lead to engine or clutch problems.

Troubleshooting and Extra Tips

  • If you see oil leaks from the filter cover or drain plug, immediately shut off the bike and verify the O-ring, washer, and torque on fasteners.
  • Check your owner's manual for the latest spec updates, torque values, and oil type recommendations.
  • Change oil more frequently if riding in dusty, high-heat, or high-load conditions.

Congratulations. Your 2015 Suzuki DR650S is now protected with fresh oil and a new filter, helping to ensure many more miles of fun.
