2020 Suzuki DR650SE Oil Change Steps
-
Warm Up Your Engine
- Let the engine idle for several minutes so the oil thins and drains efficiently. Warm oil also helps contaminants flow out more easily.
-
Ensure Safe Bike Position
- Place the bike on level ground with a center stand or swingarm stand. The motorcycle must be upright and stable for a proper fill and level check.
-
Remove the Drain Plug
- Slide your drain pan under the engine’s drain bolt. Using a 17mm socket and ratchet, loosen and remove the drain plug. Allow oil to drain fully—this can take several minutes.
Tip: Replace the crush washer on the drain bolt each change for proper sealing and to prevent leaks.

Replace the Oil Filter
- With an 8mm socket, remove the three bolts on the right-side oil filter cover. Gently take off the cover—watch for oil spillage.
Remove the old filter. Check that the spring stays in the correct position inside the cover.
Install the new filter with the “open” side facing into the engine, ensuring it seats properly on the spring.
Carefully remove and replace the O-rings (one large, two small) on the oil filter cover. Lubricate new O-rings with fresh oil before installation to ensure a good seal.

Reinstall the Oil Filter Cover & Drain Plug
- Reattach the oil filter cover and tighten the 8mm bolts securely but don’t overtighten–crush the O-rings evenly for a proper seal.
Clean the drain bolt area and reinstall the plug with new washer. Tighten snugly—do not overtorque to avoid stripping the pan.

Fill with Fresh Oil
- Locate the oil fill cap on the right engine cover.
Pour in 2.3 liters (about 2.4–2.5 quarts) of quality 10W-40 motorcycle oil. (Use less if you are not changing the filter, but it’s best practice to replace the filter every oil change.)
Take care not to overfill.
- Locate the oil fill cap on the right engine cover.
-
Check Oil Level
- Start the engine and let it idle for a few minutes. Shut it off and wait one minute for oil to settle.
Hold the bike vertical and check the oil sight glass (right side of crankcase). The oil should be between the upper and lower lines on the sight window. Add oil as needed.

Owner’s Call-Outs for the 2020 Suzuki DR650SE
- Sight Glass, Not Dipstick: Oil is checked through a sight window, not a dipstick. Always hold the bike fully upright on level ground—not on the sidestand—for an accurate check. Overfilling can cause engine damage or leaks.
- Correct Oil Specification: Use 10W-40 oil that meets SE, SF, or SG API standards. Most motorcycle-specific oils satisfy this requirement, such as Motul 5100 10W-40.
- Oil Change Intervals: Suzuki recommends changing your oil every 3,500 miles (6,000 km) or sooner if you ride in severe conditions. Replace the oil filter every other oil change, but many riders swap it every time.
- Filter Spring Orientation: Double-check the spring behind the filter is there and seated correctly—it ensures proper filter function and oil flow.
- Don’t Overtighten: Both the drain plug and filter cover bolts only need to be snug. Excessive force can strip threads or crush O-rings.
