Castrol VECTON Long Drain 10W-30 CK-4 Diesel Engine Oil
Part Synthetic SAE 10W-30 Heavy-Duty Diesel Engine Oil for Extended Service Applications
Castrol VECTON Long Drain 10W-30 CK-4 is an advanced part synthetic heavy-duty diesel engine oil formulated for engines requiring SAE 10W-30 and API CK-4, CJ-4, or earlier diesel engine oil categories.
Designed around PC-11 engine oil technology, VECTON Long Drain 10W-30 is engineered to maintain lubricant performance under severe operating conditions and support longer useful oil life. Castrol specifically highlights viscosity control under high shear, TBN retention for acid neutralization, and resistance to oxidation and oil thickening at elevated temperatures.
Castrol reports testing for extended drain intervals of up to 80,000 miles or 1,000 hours. Actual oil drain intervals should always follow the engine manufacturer's recommendations and may depend on operating conditions, maintenance practices, and oil analysis.

Applications
Castrol VECTON Long Drain 10W-30 CK-4 is intended for heavy-duty diesel engines where the manufacturer specifies an SAE 10W-30 lubricant meeting API CK-4, CJ-4, or an applicable earlier diesel engine oil category.
It is particularly suited to fleets and heavy-duty equipment where extended service capability, viscosity stability, oxidation control, and lubricant durability are important.
Always confirm the required viscosity grade, API category, OEM specification, and approved drain interval in the engine manufacturer's service documentation before use.

Extended Drain Performance
Castrol VECTON Long Drain 10W-30 CK-4 is specifically engineered to support longer oil life under severe operating conditions.
Castrol reports extended drain testing to:
- 80,000 miles
- 1,000 operating hours
These figures should not be treated as universal oil-change intervals. Actual drain intervals should be established according to the engine manufacturer's maintenance recommendations, operating environment, duty cycle, and oil analysis where applicable.
High-Shear Viscosity Control
Modern diesel engines can subject engine oil to high mechanical and combustion pressures. Castrol states that VECTON Long Drain 10W-30 CK-4 is formulated to maintain viscosity under high-shear conditions, helping the lubricant remain within its intended performance range during service.
TBN Retention and Acid Control
Combustion can produce acidic byproducts that contribute to corrosion within the engine. Castrol highlights the product's ability to maintain its total base number, or TBN, during extended service, helping neutralize acids that can affect bearings and other engine components.
High-Temperature Oxidation Control
Elevated engine temperatures can accelerate lubricant oxidation and contribute to oil thickening. VECTON Long Drain 10W-30 CK-4 is formulated to resist oxidation and help maintain oil performance throughout the service interval.
Frequently Asked Questions
Is Castrol VECTON Long Drain 10W-30 synthetic?
Castrol describes VECTON Long Drain 10W-30 CK-4 as an advanced part synthetic heavy-duty engine oil.
Does Castrol VECTON Long Drain 10W-30 meet API CK-4?
Yes. API CK-4 is listed among the product's current performance specifications.
Can Castrol VECTON Long Drain 10W-30 replace API CJ-4 oil?
Castrol states that the product can be used in diesel engines where API CK-4, CJ-4, and previous diesel engine oil categories are required. Always verify that SAE 10W-30 is also appropriate for the engine.
How long can Castrol VECTON Long Drain 10W-30 go between oil changes?
Castrol reports testing for extended drain intervals of up to 80,000 miles or 1,000 operating hours. Actual drain intervals should follow the engine manufacturer's requirements and may need to be established through oil analysis and operating history.
What does "Long Drain" mean for Castrol VECTON?
The Long Drain designation refers to the oil's formulation for extended useful oil life. Castrol emphasizes shear stability, TBN retention, and oxidation resistance as factors supporting longer service intervals.
Does Castrol VECTON Long Drain 10W-30 meet Cummins CES 20086?
Yes. Cummins CES 20086 is listed in the current Castrol product information.
Does Castrol VECTON 10W-30 meet Volvo VDS-4.5?
Yes. Volvo VDS-4.5 is listed among the supported specifications.
Does Castrol VECTON Long Drain 10W-30 meet Mack EOS-4.5?
Yes. Mack EOS-4.5 is listed by Castrol for this product.
Does Castrol VECTON 10W-30 meet Detroit Diesel DFS 93K222?
Yes. Detroit Diesel DFS 93K222 is included in the current performance specifications.
Does Castrol VECTON Long Drain 10W-30 meet Ford WSS-M2C171-F1?
Yes. Ford WSS-M2C171-F1 is listed by Castrol.
Does Castrol VECTON 10W-30 meet Caterpillar ECF-3?
Yes. Caterpillar ECF-3 is included in the current specification list.
Is Castrol VECTON Long Drain 10W-30 suitable for Deutz engines?
It can be used in applications requiring Deutz DQC III-10 LA, provided SAE 10W-30 is the correct viscosity for the engine.
What is TBN and why does it matter in diesel engine oil?
TBN, or Total Base Number, relates to an oil's ability to neutralize acidic combustion byproducts. Castrol specifically highlights TBN retention as part of VECTON Long Drain 10W-30's extended-service performance.
Can I use Castrol VECTON 10W-30 instead of 15W-40 diesel oil?
Only if SAE 10W-30 is specified or permitted by the engine manufacturer. API category compatibility alone does not mean different viscosity grades are automatically interchangeable.
