How to Change the Oil in a 1995 Suzuki DR250: The Complete MotoSport.com Guide
Regular oil changes are key to keeping your 1995 Suzuki DR250 running smoothly and extending the life of your engine. The DR250 uses a dry-sump oil system rather than the more familiar wet-sump system, so there are a few extra steps and model-specific details to keep in mind. Here's your proprietary step-by-step guide, tailored for MotoSport.com readers, covering tools, procedures, and important tips for your DR250.
Tools and Supplies Needed
- Socket wrench set (including 12mm and 14mm sockets)
- Drain pan
- Funnel
- New crush washers for drain bolts
- Replacement oil filter
- Replacement oil (1.9 liters with filter change, see manufacturer's recommendation for oil type)
- Clean rags
- Torque wrench (recommended but optional)
- Gloves (optional, for cleaner hands)
Step-By-Step Instructions
-
Warm up the Engine
Start and let your bike idle for several minutes. This warms the oil, helping it drain completely. -
Remove Skid Plate
The DR250's drain plugs and frame oil screen are best accessed with the skid plate off. Use the appropriate socket to remove the bolts and set the plate aside.
Tip: Some owners skip this, but for a thorough oil change and strainer check, remove the guard. -
Drain Crankcase Oil
Place your drain pan under the engine's crankcase. Use a 14mm socket to remove the crankcase drain bolt (bottom of engine). Allow all old oil to drain out. Replace the old crush washer with a new one to avoid leaks. -
Drain Oil from Frame Reservoir
The DR250's dry sump stores some oil in the frame. Locate the frame drain bolt (usually requires a 12mm socket) and remove it, draining oil into the pan. Replace the crush washer here as well. -
Remove and Inspect Oil Filter
The oil filter is typically housed on the right side of the engine, behind a cover secured by small bolts. Remove these bolts and take out the filter.
Inspect the old filter for metal particles or signs of engine wear. Replace the oil filter with a new one, making sure the rubber gasket comes off with the old filter, and lightly oil the new gasket before installation. -
Check and Clean Oil Screen (Strainer)
The DR250 includes an oil screen in the frame reservoir. Remove it according to your service manual's guidance and clean thoroughly before reinstalling. This is an extra filtration step, important for off-road and older machines. -
Reinstall Everything
Refit the drain bolts (frame and crankcase) and tighten securely–avoid over-tightening, as the threads in the engine case can strip. Use a torque wrench if possible; refer to your owner's manual for specs. Refit the oil filter cover with the new filter in place, securing the bolts evenly. Reattach the skid plate last, ensuring all fasteners are snug. -
Refill with Fresh Oil
Remove the oil fill cap (usually on the frame or engine side cover, depending on your DR250's exact configuration) and use a funnel to add oil. The capacity is 1.9 liters with a filter change. Pour in about 90% of the total volume, wait a minute, then check the oil level via the dipstick or sight glass if equipped. Top up gradually until full. -
Run and Check for Leaks
Start the engine and let it idle for a couple of minutes, then turn it off and check all drain bolts and the filter cover for leaks. Recheck the oil level, as it may drop once circulated through the system; top up as needed. -
Final Checks
Dispose of the old oil and filter properly. Ride the bike gently, then re-inspect for leaks and confirm oil level after the first short ride.
1995 Suzuki DR250 Specific Call-Outs
-
The 1995 DR250 uses a dry sump system—both the motor's crankcase and the frame contain oil and require draining.
Neglecting the frame reservoir means you'll leave about half the old oil in the system during service. - Oil capacity (with filter): 1.9 liters.
- Always inspect and, if possible, clean the frame oil screen to protect the top end from oil starvation.
- Draining both the crankcase and the frame, plus inspecting the screen, prevents oil contamination and maximizes engine life.
- Always use new crush washers to minimize the risk of leaks from the drain bolts.
- Do not over-torque drain bolts–damaging these threads can lead to costly engine repairs.
Recommended Oil and Filters for the 1995 DR250
- Use a quality 4-stroke motorcycle oil in the recommended viscosity for your climate; check your owner's manual for exact specifications.
