🛠 Product Description

GO-PRO 4T G.MS 1040 1QT
Semi-synthetic 4-stroke motorcycle oil that blends the cost efficiency of mineral oil with the stability of synthetics. The low-phosphorus formula is catalyst-friendly (protects three-way catalytic converters) and delivers corrosion resistance, low sludge formation, and high shear stability for small-displacement, high-rev engines. Compatible with EFI systems and ceramic cylinders, and tuned for smooth, easy control in urban stop-and-go riding—particularly friendly for lighter throttle habits.

Product Features:
✅ Semi-synthetic formula: Better high-temperature and oxidation resistance than straight mineral oil.
✅ 1040 grade: Quick cold-start flow and a stable oil film at operating temperature.
✅ Low-phosphorus, catalyst protection: Helps extend the life of the catalytic converter and after-treatment.
✅ Corrosion resistant · low sludge: Keeps internals cleaner for sustained efficiency.
✅ High shear stability: Maintains viscosity and protection in small high-rev engines and prolonged heat.
✅ Smooth ride feel: More linear power delivery and easier stop-and-go control (city/female-friendly tuning).
✅ Compatibility: Suitable for EFI systems, ceramic cylinders, and small high-rev 4T engines.

How to Use:

1. Follow the owner’s manual for the specified viscosity and change interval.

2. Warm the engine for 3–5 minutes, then drain the oil (vehicle-specific); replace the oil filter if equipped.

3. Refill to the specified quantity; idle to check for leaks and confirm the oil level.

Applications:

• 4-stroke motorcycles

• Small-displacement, high-rev engines; EFI systems; ceramic cylinders

• City commuting, everyday road use, and short-to-medium trips; friendly for female/new riders
