Product Information
Full details
This Morris Multivis CST HP 5W-40 synthetic technology engine oil is designed for modern passenger car and van engines, including turbocharged and supercharged units. It offers superior protection and performance compared to conventional oils, ensuring excellent flow at low temperatures and robust film strength at high temperatures, while minimizing oil consumption. A key caveat is its use with VW 501.01/505.01 standards, which is limited to fixed service intervals.

FAQs
What is the main advantage of synthetic technology in this oil?
Synthetic technology provides superior lubrication, better protection against wear in extreme temperatures, improved flow at low temperatures, and lower volatility compared to conventional oils.
Can I use this oil in my older car?
While designed for modern engines, it may be suitable for some older vehicles if the required specification (e.g., API SN/CF, ACEA A3/B4) and viscosity (5W-40) match the manufacturer's recommendations. Always check your owner's manual.
What does 'low volatility' mean for my engine?
Low volatility means less of the oil evaporates at high engine temperatures. This helps maintain the correct oil level, reduces the need for frequent top-ups, and prevents harmful deposits from forming.
Is this oil suitable for diesel engines?
Yes, this oil meets the API CF specification, making it suitable for many modern diesel engines.
What is the significance of the 'fixed service intervals' for VW standards?
It means that if you are using this oil to meet VW 501.01/505.01 standards, you must strictly adhere to the oil change schedule recommended by VW for fixed intervals, rather than variable or extended intervals.
How does this oil improve engine cleanliness?
Its improved thermal stability and resistance to breakdown help prevent the formation of sludge and harmful deposits within the engine, keeping internal components cleaner.
Troubleshooting
Engine runs noisy, especially on startup
Verify the correct oil viscosity (5W-40) and specification are being used. Ensure the oil level is adequate. A sudden change in oil type may require an initial adjustment period.
Increased oil consumption
Check for external leaks. The low volatility of this synthetic oil minimizes internal evaporation, but very high mileage engines might still consume oil. Ensure the oil is not being forced past worn seals or piston rings.
Oil pressure warning light illuminates
Immediately stop the engine and check the oil level. If the level is correct, there may be an issue with the oil pump or a significant leak. Consult a qualified mechanic.
