Fork oil

Identify the fork and specified fluid

Use the fork manufacturer's service information for the exact model and version. Compare the specified fluid with the oil's technical data, including the grade and stated application. A similar name or grade label should prompt a specification check rather than an assumed replacement.

Check the quantity for the planned service

Find the fluid quantity for the particular service in the fork instructions and compare it with the container volume supplied. Keep purchasing quantity separate from any fill-level instruction. Browse suspension for related components, checking their application independently of the oil.

Can fork oil also be used in a rear shock?

Only choose it if the shock manufacturer's requirements and the oil's stated application support that use. A fork-oil label alone does not establish shock compatibility. Separately listed shock parts also need to match the exact suspension unit.

Is the same grade label enough when changing brands?

Confirm the alternative against the suspension manufacturer's specified fluid and the oil's technical data. Do not infer an exact replacement from the grade label alone. If the required comparison is unclear, establish the accepted alternative before ordering.

Will a different grade improve the suspension?

Choose the specified grade for the intended service. A different label does not establish a suitable improvement for your suspension or use. Have any proposed change confirmed for the exact fork before selecting oil; this category does not prescribe a suspension setup.

What if I cannot find the specified fork oil?

Confirm an accepted alternative with the fork or oil manufacturer before substituting another fluid. The wider oils category can help locate a named oil type, but another oil's similar appearance or viscosity label does not establish suitability for the fork.
