Engine Oils Product Data castrol.com/GPS 800 255 4417 May 2025 GPS Castrol ® VECTON ® Long Drain 10W-30 CK-4 Castrol VECTON Long Drain 10W-30 CK-4 with unique SYSTEM PRO TECHNOLOGY™ is an advanced part-synthetic heavy-duty diesel engine oil that conforms to requirements of PC-11 engine oil technology. Specifically engineered to deliver longer oil life and enable longer service intervals even under severe operating conditions, Castrol VECTON Long Drain 10W-30 CK-4 can be used in diesel engines where API CK-4 or CJ-4 and previous diesel engine oil categories are required. Extended Oil Life and Extended Drain Intervals New technology developments in diesel engines have led to lower emissions in heavy-duty vehicles. In turn, these advances in technology also result in increasing levels of torque within the engine, which leads to higher pressures and temperatures. Castrol VECTON Long Drain 10W-30 CK-4 adapts to increased pressure and temperature with its proven shear stability and oxidation performance, extending useful life of the oil for longer service intervals and higher productivity. In addition, Castrol VECTON Long Drain 10W-30 CK-4 delivers extended drain intervals of up to 80,000 miles or 1,000 hours. ^ Features/Benefits Castrol VECTON Long Drain 10W-30 CK-4 with unique SYSTEM PRO TECHNOLOGY™ offers the following benefits to support modern diesel engine technology: • Delivers a 45% extra performance reserve* that fights oil breakdown by helping to control oxidation, re- duce deposits and neutralize harmful acids. It also adapts to higher temperatures, which helps to main- tain viscosity. is means longer useful oil life, giving you confidence in your maximum drain interval. ^ • Excels under high pressure. Engine combustion pressures are increasing, which puts increased pressure on key engine parts. Castrol VECTON Long Drain 10W-30 CK-4 is formulated to hold its viscosity under high shear contacts to extend oil life. • Performs at high temperature. In modern engines, engine oil is subjected very high temperatures, causing oxidation and thickening. Castrol VECTON Long Drain 10W-30 CK-4 fights oxidation, extending oil life. • Neutralizes harmful acids and combustion by-products that cause bearing corrosion. Castrol VECTON Long Drain 10W-30 CK-4 maintains outstanding TBN level even while operating at maximum drain intervals. ^Extending oil drain intervals should only be done in conjunction with a proper used oil analysis program like Castrol Labcheck © *Average of percentages by which VECTON exceeds the industry standard requirement limits in API CK-4 and ACEA E9-16 engine tests for viscosity maintenance, heat protection, deposit control, minimum oil limits and acid neutralization. In API CK-4 tests only, the VECTON performance reserve is 37%. B6 ecastrof
