FAQs

What does '5W40' mean?

'5W' refers to the oil's viscosity at cold temperatures (winter), indicating it flows well when the engine is cold. '40' refers to the oil's viscosity at operating temperature (100°C), indicating its thickness when the engine is hot. 5W40 offers a good balance for a wide range of conditions.

Can I use this oil in an older car?

This oil is specifically recommended for current and late-model petrol and diesel cars, especially high-performance and turbocharged ones. While it might not harm an older engine, it's best to use the oil specification recommended in your vehicle's owner's manual for optimal performance and compatibility.

How often should I change the oil?

Refer to your vehicle's owner's manual for the recommended oil change interval. This can vary significantly based on driving conditions, vehicle type, and manufacturer recommendations. Generally, fully synthetic oils allow for longer intervals than conventional oils.

What is the difference between fully synthetic and other oils?

Fully synthetic oils are chemically engineered to provide superior lubrication, stability, and protection under extreme temperatures and pressures compared to conventional or semi-synthetic oils. They offer better resistance to breakdown and evaporation.

Is this oil suitable for all petrol and diesel engines?

It is suitable for current and late-model petrol and diesel cars where the manufacturer specifically calls for a 5W40 fully synthetic engine oil. Always check your vehicle's manual for confirmation.

Does this oil help with fuel economy?

Fully synthetic oils, due to their ability to reduce friction and improve lubrication, can contribute to slightly better fuel efficiency compared to lower-grade oils. However, the primary benefits are engine protection and performance.

Troubleshooting

Engine oil pressure warning light stays on after starting.

Check the oil level immediately. If low, top up. If the level is correct, the issue may require professional diagnosis of the oil pump or sensor.

Increased oil consumption noticed.

Verify the oil level is not overfilled. Check for external leaks. If no leaks are found and consumption is significant, consult your vehicle manual or a mechanic, as it could indicate internal engine wear.

Engine running rougher than usual.

Ensure the correct grade and type of oil has been used. Check oil level and condition. If the oil is old or contaminated, an oil and filter change may be necessary. Persistent roughness requires further mechanical inspection.

Setup, Compatibility & Care

Compatibility: This oil is recommended for use in current and late-model petrol and diesel cars where the manufacturer specifically calls for a 5W40 fully synthetic engine oil. Always consult your vehicle's owner's manual to confirm the correct oil specification before use. It is particularly suited for modern high-performance and turbocharged engines.

Setup: Engine oil change procedures vary by vehicle. Generally, it involves draining the old oil from the sump, replacing the oil filter, and refilling with the correct quantity of new oil. Ensure the vehicle is on a level surface and properly supported before commencing.

Care: Regularly check your engine oil level and condition using the dipstick. Top up with the correct specification oil if necessary between scheduled changes. Adhere to the manufacturer's recommended oil change intervals to ensure optimal performance and engine protection. Store the oil container in a clean, dry place, away from direct sunlight and extreme temperatures.
