Castrol GTX 5W-30 C4, Synthetic Motor Oil, 4L

Castrol GTX 5W-30 C4 is a time-tested solution for drivers who value engine longevity. Its unique 3X-Clean formula is engineered to fight the three main causes of engine sludge: heat, contaminants, and short trips. The oil actively cleans away existing sludge and creates a barrier to prevent new deposits, keeping engines 35% cleaner than industry standards require.

Application: This oil is suitable for gasoline and diesel engines where the manufacturer recommends a 5W-30 lubricant with an ACEA C4 specification.

What the designations mean:

• 5W-30: An all-season viscosity grade. "5W" ensures easy starting in cold temperatures (down to -36 °C), while "30" guarantees optimal protection at the engine's operating temperatures.

• C4: This is an ACEA specification for low-SAPS oils (low Sulphated Ash, Phosphorus, and Sulphur) designed to extend the life of Diesel Particulate Filters (DPF) and catalytic converters.

Why this oil?

• Extended Engine Life: The 3X-Clean formula delivers superior protection against sludge caused by contaminants, heat, and frequent short trips, which helps to significantly extend the life of your engine.

• High Performance: The oil provides advanced protection against thermal breakdown and viscosity loss, as well as exceptional protection against high-temperature deposits.

• Emission System Protection: Thanks to the ACEA C4 specification, this oil is ideal for modern diesel engines with particulate filters, helping them to operate longer and more efficiently.

• Premium Quality: Contains premium synthetic technology base oils and anti-wear additives.

Important Note: Always consult your vehicle's owner's manual for the correct oil selection.
