Questions & answers

What is this oil best for?

Sports and touring motorcycles with a wet clutch, where the manufacturer specifies a 5W-40 grade — a good all-rounder within the wet-clutch-safe range.

How does this compare to the 10W-60 and 15W-50 Formula GT oils?

Same wet-clutch-safe JASO MA2 formulation; the 5W-40 grade suits engines built around a lighter running viscosity, while the 10W-60 and 15W-50 suit engines specified for a thicker hot-running film.

Is it safe for a wet clutch?

Yes — JASO MA2 confirms no friction modifiers, so it won't cause clutch slip.
