⚡ At a Glance
- • Engine Protection: Part-synthetic formulation reduces wear and supports smooth running under load
- • Best for: Owners of 4-stroke motorcycles needing oils meeting API SL and JASO MA/MA2
- • Not ideal for: Two-stroke engines or bikes specifying a different viscosity or higher API rating
Part-synthetic 10W-30 oil meeting API SL and JASO MA2, developed for modern 4-stroke engines. Supplied in a 1L pack with an easy-pour nozzle for tidy top-ups.
Robust wear control - with part-synthetic formulation
Part-synthetic base oil blends combine mineral and synthetic components to balance protection and viscosity stability. API SL and JASO MA2 approvals indicate formulation engineered for current 4-stroke lubrication demands.
Consistent wear protection helps extend engine life on bikes used for daily commuting or spirited weekend rides. Riders can expect reliable protection across varied riding conditions.
Consistent running across conditions - thanks to 10W-30 viscosity
The 10W-30 grade provides lower-temperature flow at start-up while maintaining film strength at operating temperature. That balance supports smooth oil circulation in both carburettor and fuel-injected engines.
Quick cold starts with stable protection once warm, useful for mixed urban and longer rides. Viscosity suits many small and mid-capacity 4-stroke motorcycles.
Cleaner, less messy refills - with easy-pour nozzle
A user-reviewed easy-pour nozzle reduces splashing and helps direct oil precisely into the filler neck. The packaging design removes the need for a separate funnel during routine top-ups.
Faster, tidier oil changes and top-ups, particularly helpful when servicing at home or on the roadside. Reduces waste and the chance of spills on engine surfaces.
