Millers Oils Trident Professional C3 5W-30 Engine Oil - 1 Litre

Fully synthetic oils offer superior lubrication, better thermal stability, and enhanced protection against wear compared to conventional oils, especially under extreme temperatures and demanding driving conditions.

This oil is specifically formulated for modern engines that require a C3 specification for emissions systems. It is essential to check your vehicle's owner manual to ensure compatibility. It may not be suitable for older vehicles with different oil requirements.

It is generally not recommended to mix different types or brands of engine oil, especially fully synthetic with conventional. Mixing can alter the oil's properties and potentially compromise its performance and protective qualities. If a mix is unavoidable, use the same viscosity grade and specification if possible, and consider an oil change soon after.

ACEA C3 is a European standard for engine oils designed for use in modern gasoline and diesel engines equipped with exhaust after-treatment devices. It indicates the oil has 'Mid SAPS' (Sulphated Ash, Phosphorus, Sulphur) content, which is crucial for protecting particulate filters and catalytic converters.

This oil allows for modern, longer oil change intervals. However, the exact interval depends on your vehicle manufacturer's recommendations, driving conditions, and mileage. Always refer to your vehicle's owner's manual for the manufacturer's specified interval.

During cold starts, engine wear is at its highest as the oil is thicker and takes time to reach all parts of the engine. Oils formulated for easy cold start performance circulate quickly, providing immediate lubrication and minimizing this critical wear.

Check the oil level immediately. If low, top up with the correct specification oil. If the level is correct, the issue may be with the oil pump or sensor; consult a mechanic.

Ensure the correct oil specification was used. Some synthetic oils may take a short period to circulate fully. If the problem persists, check for proper filter installation and consult a mechanic.

This could indicate oil is burning. Check for oil leaks and ensure the correct oil viscosity and specification are being used. Persistent smoke may point to internal engine wear; seek professional diagnosis.
