Product Description
KATMOTO K6 HEAVY DUTY 20W-50 is a synthetic high-viscosity engine oil designed for older gasoline engines, high-mileage vehicles and hot-climate operation requiring API SL/CF performance. Its thick 20W-50 oil film helps reduce oil consumption, support compression sealing and protect worn engine parts under high-temperature, heavy-load and severe daily service conditions.
Key Performance Features
| Thick 20W-50 oil film
designed for older, worn or high-mileage engines. |
Hot-climate protection
maintains strong viscosity under high ambient temperature and heavy load. |
| Reduced oil consumption support
thicker film helps reduce burn-off in older engines. |
API SL/CF performance
suitable for traditional gasoline and selected light-duty diesel applications. |
| Engine cleanliness
detergent system helps manage sludge and deposits in older engines. |
Practical high-mileage solution
suitable for older passenger cars, vans, utility vehicles and warm-market fleets. |
Applications & Performance Level
| Applications | Older gasoline vehicles, high-mileage engines, warm-climate vehicles, utility vehicles, light vans and selected light-duty diesel applications requiring SAE 20W-50 API SL/CF oil. |
| Suitable For | API SL/CF, API SJ/SF backward-compatible gasoline applications, and selected non-DPF diesel applications where SAE 20W-50 and API CF are specified. |
| Important Notice | Not recommended for engines requiring low-viscosity fuel-economy oils, modern after-treatment systems, DPF/GPF compatibility, or current OEM-specific approvals. |
