FAQs
Is this oil suitable for daily street use?
While it offers excellent protection, Motorex Racing Pro 4T 0W/40 is specifically formulated for the extreme demands of racing. For daily street use, a dedicated street motorcycle oil may be more appropriate and cost-effective, unless your motorcycle's manual specifically recommends this grade for all conditions.
What is the difference between 0W/40 and other viscosities?
The '0W' indicates its viscosity at cold temperatures (W for Winter), meaning it flows well when the engine is cold, aiding startup protection. The '40' indicates its viscosity at operating temperature, providing robust protection when the engine is hot. Other viscosities offer different balances of cold flow and hot protection.
How often should I change this racing oil?
For racing applications, oil change intervals are typically much shorter than for street use and depend heavily on usage (e.g., race duration, number of sessions). Consult your race team or motorcycle service manual for specific recommendations, but expect frequent changes.
Can I mix this oil with other brands or types of oil?
It is strongly recommended not to mix different oil brands or types, especially with a specialized racing oil. Mixing can alter the oil's properties and potentially compromise performance and protection. Always use the same type and grade of oil for top-ups and changes.
What does 'Fully Synthetic' mean for this oil?
Fully synthetic oils are chemically engineered in a laboratory to provide superior lubrication properties, greater resistance to breakdown at high temperatures, better flow at low temperatures, and overall enhanced protection compared to conventional or semi-synthetic oils.
Where is Motorex Racing Pro 4T 0W/40 manufactured?
Motorex is a Swiss company, and their high-performance racing lubricants are developed and manufactured in Switzerland.
Troubleshooting
Engine runs hotter than usual.
Ensure the correct oil viscosity (0W/40) is used and the oil level is correct. Verify that the cooling system is functioning properly and that there are no obstructions to airflow.
Clutch slipping during gear changes.
Confirm that the oil is indeed Motorex Racing Pro 4T 0W/40, which is designed for wet clutches. If the issue persists, inspect the clutch plates and springs as per your motorcycle's service manual.
Oil appears discolored or has debris.
This could indicate internal engine wear or contamination. Check the oil filter for excessive metal particles. A sample analysis may be required. Ensure you are using genuine Motorex oil and replacing the filter at recommended intervals.

Setup, Compatibility & Care
Setup: This is a direct replacement for your motorcycle's existing engine oil. Ensure your engine is at operating temperature before draining the old oil to facilitate complete removal. Always refill with the correct amount of oil as specified in your motorcycle's owner's manual. Consult your manual for the correct oil filter replacement procedure.
Compatibility: Primarily developed for the latest generation of 4-stroke motorcycles, especially 4-cylinder Superbike and supersport race applications. It is specifically recommended for inline 4-cylinder engines and the KTM RC 8. Always verify compatibility with your specific motorcycle model's owner's manual or manufacturer recommendations.
Care: Store the 4-litre container in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure the cap is tightly sealed when not in use to prevent contamination and evaporation. Dispose of used oil responsibly according to local regulations; never pour it down drains or onto the ground. Regular oil changes, following your motorcycle manufacturer's recommended intervals, are essential for maintaining engine health.
