A regular oil change is crucial for the longevity and performance of your 1996 Suzuki DR350. This guide—designed exclusively for MotoSport.com readers—will walk you step-by-step through the process, highlighting any critical call-outs specific to this legendary dual-sport dirt bike.

Tools and Supplies Needed

  • 17mm, 12mm, 10mm, and 19mm wrenches or sockets
  • 8mm socket (optional, depending on aftermarket skid plate)
  • Flathead screwdriver
  • Pair of needle nose pliers
  • Oil drain pan
  • New oil filter (HighFlo or OEM, refer to your manual for part number)
  • Fresh oil—10w40 motorcycle oil (Suzuki recommends this for the DR350)
  • New crush washers (for drain bolts)
  • Gloves and shop towels

Specific Call-Outs for the 1996 Suzuki DR350

  • Dry-sump oil system: The DR350 stores oil in the frame, not just the engine.
  • Frame oil screen: There's an oil screen inside the frame that should be inspected and cleaned periodically—though not every oil change.
  • Skid plate location: To do a thorough oil change, you should remove the skid plate for access to all drain bolts and the screen.
  • Caution: Be careful not to overtighten drain bolts; the aluminum engine casing is susceptible to stripped threads.

Step-By-Step Oil Change Instructions

  1. Warm Up the Engine
    Start the bike and let it idle for 3–5 minutes. This helps suspend any particulates and ensures thorough draining.
  2. Remove the Skid Plate
    With the engine off and the bike on a stand, use a 12mm socket or wrench to remove the four bolts holding the skid plate. Set the plate and bolts aside.
  3. Position the Oil Drain Pan
    Place an oil drain pan under the crankcase drain bolt, found on the bottom of the engine.
  4. Drain Engine Oil
    Use a 17mm socket/wrench to remove the crankcase drain bolt. Allow the oil to drain completely. Remove and replace the crush washer before reinstalling the bolt.
  5. Drain Frame Oil
    Locate the oil drain bolt on the lower right side of the frame's front tube. Use a 12mm socket to remove it and let the frame oil drain thoroughly. Again, replace the crush washer before tightening.
  6. (Optional but Recommended) Clean the Frame Oil Screen
    Unscrew and remove the fitting to access the oil screen in the frame (often requires a wrench and possibly needle nose pliers). Pull out the screen, inspect for debris, clean if needed, and reinstall. This step is essential every few oil changes or after engine break-in.
  7. Replace the Oil Filter
    On the right side of the engine, remove the oil filter cover bolts with a 10mm wrench. Remove the old filter and clean the housing. Insert a new filter (ensure the spring is correctly seated), then reinstall the cover and bolts.
  8. Reinstall Drain Bolts and Skid Plate
    Once oil is fully drained and everything is clean, reinstall and tighten all drain bolts (do not overtighten). Reattach the skid plate using the 12mm socket or wrench.
  9. Refill with Fresh Oil
    Remove the oil fill cap (on the frame neck) and add approximately 2 quarts of 10w40 motorcycle oil. Pour slowly, allowing the oil to drain into the tank.
    Tip: Kick the engine over a few times (with the ignition off) to help circulate oil through the system before checking the level.
  10. Check Oil Level
    Start the engine and idle for a minute. Stop and wait 2 minutes, then check the oil using the dipstick. Add oil if necessary until the correct level is reached (between the dipstick lines).
  11. Dispose of Old Oil Responsibly
    Take your used oil and filter to an authorized recycling center.

Additional Tips and Maintenance

  • Inspect for Leaks: After your first ride, check all bolts and drains for leaks.
  • Intervals: Change the oil every 1,000–2,000 miles or more often under harsh riding conditions.
  • Gaskets & Seals: Always inspect and replace any worn gaskets or O-rings when changing the filter.

By following these detailed steps, you'll keep your 1996 Suzuki DR350 running strong for miles of adventure. For genuine parts, filter kits, and 10w40 oil, trust MotoSport.com—your source for premium dirt bike maintenance products and riding gear.
