Synthetic Blend 10w30 Diesel Oil Case 1 Gallon

Lucas Oil Synthetic Blend 10W30 Diesel Oil is a premium diesel engine lubricant formulated to meet CK4 specifications, delivering dependable protection in both light-duty and heavy-duty diesel applications. This 1-gallon jug is engineered to provide robust engine protection while managing the demanding thermal and oxidation stresses that diesel engines encounter during regular operation and extended intervals.

The 10W30 viscosity grade offers excellent cold-start flow in winter conditions while maintaining film strength at operating temperature—a critical balance for diesel engines that can experience rapid temperature swings during duty cycles. The synthetic blend formulation enhances oxidation stability and thermal performance compared to conventional mineral oils, reducing deposit accumulation on pistons and injectors. This composition extends drain intervals and supports injector cleanliness, a key concern for modern common-rail diesel systems where fuel quality varies. The CK4 specification confirms compliance with the latest API standards for 2017 and newer diesel engines.

Diesel operators—whether in fleet, agricultural, construction, or recreational applications—benefit from the balanced protection this oil delivers. The synthetic blend is particularly suited for operators who want enhanced performance over conventional oils without the premium cost of full synthetic formulas. The 1-gallon container format allows for convenient storage and portability, making it practical for field service, mobile maintenance, or equipment kept at remote job sites.

Lucas Oil has a long-standing reputation in the diesel market for formulations that address real-world operational demands. This synthetic blend sits in a proven sweet spot for owners seeking better protection than conventional mineral oil without stepping into full synthetic pricing. Check your owner's manual to confirm 10W30 is the correct viscosity grade for your specific engine before use.
