FAQs
Is this oil compatible with my air fork?
Yes, this oil is compatible with all oil-damped bicycle forks, including air-sprung models that use oil for damping.
Can I mix this with other brands of shock oil?
It is highly recommended to stick to one brand and type of oil to ensure the chemical properties remain consistent and to prevent potential reactions.
Does 15 Wt oil make the fork stiffer?
It makes the damping slower, which can feel 'stiffer' or more controlled to some riders compared to lighter 5 Wt or 7 Wt oils.
How often should I change my shock oil?
Follow your fork manufacturer's suggested service interval, which is typically every 50 to 200 hours of riding depending on the conditions.
Is this safe for plastic or rubber seals?
Yes, it is designed to be 100% compatible with all common suspension seal materials.
Troubleshooting
Fork feels sluggish or unresponsive
The 15 Wt oil may be too heavy for your riding style or fork setup. Verify the manufacturer's recommended weight for your fork model.
Suspension is "weeping" or leaking
Check your fork seals for wear or damage. While the oil is compatible with all seals, it cannot repair existing damaged or hardened seal rubber.
Damping consistency changes during a ride
Ensure that the fork was properly bled of all air bubbles during the oil change process.

Setup, Compatibility & Care
To use this product, always consult your fork manufacturer’s service manual to confirm that 15 Wt is the recommended oil weight for your specific model. When performing a change, ensure the fork internals are cleaned of old, contaminated fluid using an appropriate degreaser before adding the fresh Finish Line oil. Always work in a clean environment to prevent dirt or debris from entering the suspension chamber. Store the bottle in a cool, dry place and ensure the cap is tightened securely to prevent moisture contamination.
