Overview
The Lucas Oil SAE 15W-40 CJ-4 Truck Oil, part number 10296, is a conventional 15W-40 motor oil blended from high quality base stocks and an exclusive high performance additive package. The title identifies it as a CJ-4 truck oil in the 15W-40 grade.
The oil is designed to keep drag to a minimum, support extended engine life and longer oil life for extended drain periods, and make cold weather starting easier. It is labeled universal fit, so it is not built around one truck model.
Key features
- Conventional base with a 15W-40 grade
- Minimum drag
- Extended engine life
- Longer oil life for extended drain periods
- Easy cold weather starting
Choosing the right oil grade
Oil grade numbers such as 15W-40 indicate how the oil flows at cold and at operating temperature. The first number reflects cold-start flow, and the second reflects flow at operating temperature. Matching the grade to what the owner’s manual requires keeps lubrication in the range the engine was designed for.
CJ-4 is an API category for diesel engine oils, aimed at engines with exhaust aftertreatment. Gasoline and diesel engines may have different oil requirements, so confirm the category against the engine type before use. Drain intervals depend on operating conditions, including towing, dusty roads and short trips, so change the oil sooner under severe use.
- Check the owner’s manual for the required grade
- Change oil sooner under severe use
- Confirm the oil category before pouring
