ECO MATIC 15W-40 CJ-4
(18L, 200L)
ECO MATIC 15W-40 CJ-4 is a synthetic blend heavy-duty diesel engine oil meeting API CJ-4 – the advanced specification for low-emission engines with DPF and EGR systems. With proprietary Smoke Free Technology, it reduces visible exhaust emissions while delivering outstanding soot control and wear protection. The 15W-40 viscosity provides broader cold-start coverage than 20W-50, making it the preferred choice for mixed-climate and variable-temperature fleet operations.
Key Benefits
- API CJ-4 certified - fully compatible with DPF and EGR low-emission diesel engines
- Smoke Free Technology - significantly reduces visible exhaust emissions
- Wider 15W-40 temperature range - better cold-start protection vs 20W-50
- Low ash formulation (CJ-4 limits) - protects DPF and aftertreatment systems
- Outstanding soot dispersancy and TBN retention for extended drain intervals
- Backward compatible with CI-4+, CH-4, CG-4, and CF-4 diesel specifications
Applications
- Heavy-duty diesel trucks, buses, and commercial vehicles with DPF/EGR systems
- Low-emission fleets requiring CJ-4 certified oil
- Mixed-climate operations needing 15W-40 cold-start performance
- Available in 18L pails and 200L drums
