Keeping your 2022 Suzuki DR-Z400SM running strong and reliable starts with regular oil changes. This guide walks you through every step, lists required tools, and highlights DR-Z400SM-specific tips for a smooth maintenance experience—even for first-timers.
Tools & Supplies Needed
- Ratchet and sockets (8mm, 12mm, 17mm)
- Torque wrench
- Oil drain pan
- New oil filter
- 2 quarts of 10W-40 motorcycle oil (API-rated for wet clutches)
- Funnel
- Gloves, rags, and safety glasses
- Replacement washer/crush washer for drain plugs (recommended)
- Block of wood (to steady the bike for a more complete drain, optional)
- Service manual (optional, for torque settings and reference)
Special DR-Z400SM Owner Notes
- Dry sump oil system: Your DR-Z400SM stores oil in the frame, so there are two drain plugs: one in the engine case and one in the frame base.
- Skid plate: The OEM or aftermarket skid plate may restrict access. Remove it for easier, cleaner access during your oil and filter change.
- Oil volume: 1.8L when replacing both oil and filter. Only 1.7L needed if you're not changing the filter.
- Service Interval: Suzuki recommends changing the oil initially at 600 miles, then every 3,500 miles or as needed depending on riding conditions, but more frequent changes are smart for off-road/track use.
- Secret Filter: The DR-Z has a frame filter screen as well (not always needed at every change, but inspect per maintenance schedule).
Step-By-Step Oil Change Procedure
- Warm up the engine for several minutes on idle. This helps the oil drain out faster and more thoroughly.
- Turn off the motorcycle. Park it on a stable surface. If using a block of wood to keep the bike upright, this helps drain more oil from the crankcase.
- Remove the filler cap (top of the frame) and dipstick. This allows the system to vent and encourages a smoother drain process (do this first, before removing drain bolts).
- Place your drain pan under the engine.
- Remove the engine crankcase drain plug (17mm, bottom of the right engine case). Let the oil drain completely.
- Check the condition of the drain plug and washer. Replace the crush washer if damaged, and clean off any debris from the magnetic plug if equipped.
- Reinstall the crankcase drain plug and washer. Torque to 15 ft-lbs (consult your manual for your torque wrench).
- Locate the frame drain plug (12mm, base of down tube/front of frame). Position the drain pan here and remove the plug/washer. Let all oil drain out.
- Inspect and clean or replace the frame plug washer. Reinstall the frame drain plug and torque to spec (use OEM specs; generally 10-15 ft-lbs).
- Remove the oil filter. Loosen the oil filter cover (right side of engine) using a ratchet. Take care—the area can get messy as oil drains from behind the cover. Pull the old filter straight out; note orientation.
- Install the new filter. Lightly oil the new filter's rubber seal, slide it in, and ensure it's seated properly. Pay attention to the guide pin and spring inside the filter cavity.
- Reinstall the oil filter cover. Torque the bolts evenly and not excessively tight (6-7 ft-lbs).
- Add fresh oil through the filler neck. Use a funnel to avoid spills. Start with 1.8L for a full filter/oil change.
- Replace dipstick/filler cap. Start the engine and let it idle for 3-5 minutes; check for leaks around the filter and plugs.
- Turn off the bike and let it sit for a few minutes. Check the oil level with the dipstick. Adjust as needed to bring oil within the recommended mark on the stick.
- Reinstall skid plate (if removed). Double-check plug tightness and cleanliness in the work area.
Pro Tips for the DR-Z400SM
- Use motorcycle-specific oil for wet clutches—car oil can cause clutch slippage.
- Inspect the "secret" frame oil screen every few oil changes for debris build-up (see your manual for location and removal).
- Dispose of used oil and filters at a motorcycle shop or recycling center.
- Monitor oil level periodically between changes, especially after high-speed or off-road rides.
- Keep a record of oil changes for warranty and resale value.
