Carlio diesel engine oils are produced in various grades using a combination of high-quality virgin base oils and additives. They are recommended for a wide range of diesel vehicles, both light and heavy-duty. The advanced formulation ensures not only smooth engine operation but also protects the engine against high temperatures and damages resulting from tough and heavy-duty operations. This, in turn, contributes to extending the engine’s lifespan.
The CF oil, with its more advanced formulation and stronger anti-wear additives compared to CD-grade oil, is recommended for diesel engines with indirect fuel injection and high-pressure turbocharging systems. It provides optimal performance under high-pressure conditions, making it a suitable replacement for CD-grade oil.
CD oil with a viscosity grade of 40 and 50 is suitable for lubricating various heavy-duty four-stroke diesel engines with or without turbochargers, produced before 1994. It is also recommended for all vehicles where the manufacturer advises using CD-grade oil.
