Frequently Asked Questions

What viscosity is this fork oil?

10W — a mid-weight synthetic suited to most V-twin cruiser and touring suspensions at typical riding temperatures.

Can I use this in any fork system?

Yes. Lucas Synthetic Fork Oil is compatible with all suspension damper types — telescopic, inverted, and cartridge forks.

How much oil is in one bottle?

16 oz per bottle. Most fork service requires 6–10 oz per leg depending on your bike's fork design.

Does this prevent seal damage?

Yes. The synthetic formulation resists thermal degradation and won't harden fork seals, extending their service life.

Will this improve my fork feel?

Synthetic fork oil reduces static friction and foaming, delivering more responsive damping and consistent feel through the suspension stroke.
