MWMX Parts 4T Engine Oil 10W-40 1L

Full synthetic 4 stroke engine oil built for dirt bikes: a shared gearbox, a wet clutch and race heat. Blended from PAO and ester base oils with a titanium anti wear and ZDDP (zinc) additive system, so it holds its film under load, holds its grade in the gearbox and keeps the clutch biting. No friction modifiers.

Use it in any air cooled or liquid cooled 4 stroke that calls for a 10W-40 or 15W-40 (API SG through SN): motocross, enduro, trail, ATV and quads, with or without an integrated gearbox, wet or dry clutch.

• PAO/ester base for shear stability, heat resistance and lasting protection
• Titanium + ZDDP additives guard against component wear
• High film strength under load, clean clutch engagement, precise shifts
• JASO MA2 (T903:2023), API SP
• 1 litre bottle
• Blended in Australia by an Australian owned blender with 30 years in lubricants, ISO 9001, in house chemist

Which grade: 10W-40 for cooler conditions or where your manual says 10W-40. 10W-50 for hot days, race pace and big bores.
