DS525X Engine Oil & Oil Element Change

The DS525X has one oil drainage bolt at the lower left of the engine and an oil element at the front of the engine under a cover sealed by an o-ring. The oil and the oil element are replaced together in every column of the English maintenance table Owner's manual p. 89.

Three DS525X documents are hosted on this site, and they give different values in several places. Where they give different values, this page shows every value with its page. We cannot verify which is correct. The Hungarian owner's manual is a machine translation, and its introduction names an older model (Valico 500DS/500DSX), so treat values that appear only there with caution.

Change interval

The documents give different intervals. We cannot verify which is correct.

There is no Swedish DS525X manual. The 10,000 km cadence in the Swedish DS625X and R625 manuals belongs to those models and is not used here.

Specifications

Where the manuals give different values, each value is listed with its sources and the row is marked Sources differ. We cannot verify which value is correct.

The temperature chart in the owner's manual p. 70 also shows 15W-40 and 20W-50. For winter it calls for 5W-40 or 0W-40, with a change back to 10W-40 or 20W-50 in summer. The same page warns that oil of the wrong specification or poor quality may damage the engine and EFI parts and shorten the life of the spark plugs and the catalyst.

The documents also describe the filter differently. The owner's manual describes an oil element under a cover with an o-ring Owner's manual p. 69. The workshop manual describes a secondary oil filter removed with a cap-shaped filter wrench and tightened to a torque Engine manual p. 28, and the Hungarian manual also uses a filter wrench Hungarian owner's manual p. 86. We cannot verify which matches your bike.

What you need

• Fresh SAE 10W-40 oil to the grade above, enough for the larger capacity in the table
• A new oil element of VOGE original parts
• A new copper sealing washer, and a new drainage bolt if you follow the owner's manual
• Torque wrench
• Drain pan, funnel and rags

Procedure

This follows the owner's manual p. 66-70, with the workshop and Hungarian variations noted.

1. Warm the engine

Replace the oil with the engine hot so it drains completely. The workshop manual also starts the engine first.

Danger: hot oil and the hot muffler can burn you.

2. Park upright, prepare

Hold the motorcycle upright on the parking stand (technique guide). The Hungarian manual p. 85 parks the bike on the side stand on level ground for this job and removes the lower deflector before draining.

Screw off the oil filling-up port cap anticlockwise and remove it.

3. Drain the oil

Put an oil dish under the oil drainage bolt at the lower left of the engine, remove the bolt and drain the oil.

4. Refit the drainage bolt

Fit the drainage bolt before filling with new oil. The owner's manual uses a new bolt and a new copper washer, and warns that reusing the old ones may cause oil leakage. Tighten to 28 N·m or 30 N·m as given in the table above. We cannot verify which is correct.

5. Replace the oil element

From the owner's manual:

• Replace the element after the engine oil has drained.
• Lay oil-absorbing paper or a cotton cloth under the element cover so oil does not run onto the engine when the cover comes off.
• Remove the cover and the element at the front of the engine, and drain the oil from it.
• Fit a new element.
• Refit the cover with the o-ring correctly located, or oil may leak. Check the o-ring and replace it if it is not in good condition.

The workshop manual p. 28 instead removes the filter with a cap-shaped filter wrench, oils the thread and o-ring of the new filter, and tightens it to 12 N·m. The Hungarian manual gives 26 N·m Hungarian owner's manual p. 86.

6. Refill

Confirm the element and its cover are fitted and the drainage bolt and its gasket are replaced and fitted. Fill with fresh oil through the filling-up port. The quantity differs between the documents (2.5 L or 2.7 L, see the table above). The level check in step 8 is the final check.

7. Run and check for leaks

Refit the filler cap. Run the engine at different speeds for 5 minutes and check the parts you removed for leaks Owner's manual p. 70. The workshop manual idles the engine for 3-5 minutes and then checks that there is no oil leakage Engine manual p. 27.

8. Check the oil level

The oil level window and the filling-up port are on the right crankcase. The level must sit between the UPPER and LOWER marks of the window.

The documents give different instructions on when to read it. We cannot verify which is correct.

• Owner's manual p. 66: stop the engine when it is hot, hold the bike upright and read the window.
• Workshop manual p. 27: stop the engine, wait 2-3 minutes, hold the bike upright on level ground and read the window.
• Hungarian manual p. 66-67: read it with the engine cold, with the bike upright. It says the reading is not correct with a hot engine or on uneven ground.

The level changes with oil temperature, and the bike must be vertical to the ground for the reading. If the level is above the upper mark, let some oil out at the drainage bolt. If it is below the lower mark, add oil. Check again after either. Too much or too little oil can damage the engine.

9. Disposal

Dispose of the used oil and the old element in an environmentally friendly way.

Common pitfalls

• Wrong oil. Oil of the wrong specification or poor quality may damage the engine and EFI parts.
• Reusing the drainage bolt or copper washer. The owner's manual warns this may cause oil leakage.
• Wrong oil element. A wrong element may damage the engine, so the owner's manual calls for VOGE original parts.
• Reading the window with the bike leaning. The bike must be upright.

Cross-reference

The KEL500F in the DS525X and the KEL600 in the DS625X are different engines. Don't carry capacities between them.
