API CJ-4 Synthetic Engine Oil 15W-40
15W-40 is high performance, low friction synthetic diesel oil and used for diesel engine with high output power. It's the most excellent product with our developments, researches, testing and evaluations. It decreases bubbles and reduces lubricant temperature. It is added EP anti-wear additives in order to decrease fuel consumption. And extend drain period to 20000KM.
CJ-4 meets the following standards:
1. API CJ-4
2. CCMC D-4/G-5/PD-2
Strengthes：
1. Outstanding viscosity index, provides best protection when temperature rises
2. Drain period is 20000KM.
3. Excellent oxidative stability, thermal stability and shear stability.
4. Improve fuel economy, increase energy.
5. Excellent carbon and varnish control; reduce wear.
6. Reduce diesel consuming.
7. Extends lubrication cycle, meets and exceeds drain perios recommended by plants.
8. Non toxic, non hazardous.
