Description
Here are wholesale suppliers and trader-manufacturers offering CF‑4 (and sometimes CH‑4/CI‑4) engine oil additive packages—ideal for blending diesel engine lubricants at scale:Shanghai Minglan Chemical Co.,Ltd.
CF-4 engine oil additive package is another engine oil additive package designed specifically for diesel engine oils.
CF-4 Engine Oil Additive Package – Overview
A CF-4 engine oil additive package is a pre-blended mixture of performance-enhancing chemical additives used by oil blenders and manufacturers to formulate API CF-4 grade diesel engine oils. This standard is suited for 1994 and earlier four-stroke, high-speed diesel engines, including turbocharged and naturally aspirated systems.
🔧 Function of CF-4 Additive Package:
These additive packages help the base oil achieve:
| Performance Property | Additive Function |
|---|---|
| Detergency | Keeps engine internals clean by neutralizing acids and preventing deposits (uses overbased detergents like calcium sulfonates) |
| Dispersancy | Keeps soot and contaminants suspended in oil (usually with succinimide dispersants) |
| Anti-wear protection | Prevents metal-to-metal contact (e.g., ZDDP additives) |
| Oxidation inhibition | Prevents oil thickening and sludge (antioxidants like amines/phenols) |
| Rust and corrosion prevention | Protects metal surfaces inside the engine |
| Foam control | Maintains stable oil film and pressure |
📦 Typical Additive Package Composition (approx.):
| Component Type | Typical Chemical | Role |
|---|---|---|
| Detergents | Calcium alkyl sulfonates | Neutralize acids, clean |
| Dispersants | Polyisobutylene succinimide | Soot suspension |
| Anti-wear | ZDDP (Zinc Dialkyldithiophosphate) | Surface protection |
| Antioxidants | Aromatic amines, phenols | Oxidation control |
| Rust Inhibitors | Succinic acid derivatives | Rust/corrosion resistance |
| Defoamers | Silicone oil-based | Foam control |
| Pour Point Depressants | PMA, OCP | Low-temperature fluidity |
⚙️ Performance Targets (for blended oil):
| Property | Target Value |
|---|---|
| Viscosity Grade | SAE 15W-40 (common) |
| TBN | 10–12 mg KOH/g |
| Sulphated Ash | ~1.0–1.4% |
| Phosphorus | ~0.08–0.12% |
| Zinc | ~0.10–0.14% |
🧪 Typical Treat Rate:
-
CF-4 Additive Package Treat Rate: ~7.5% to 9.0% by weight in base oil, depending on:
-
Base oil group (Group I or II)
-
Desired TBN level
-
Performance goals (cost vs quality)
-
🏭 Suitable Base Oils:
-
Group I or Group II mineral oils are commonly used
-
Can be blended into multigrade engine oils like 15W-40, 20W-50, etc.

Would you like help choosing the right package, contacting suppliers, or creating a CF-4 blending formulation? I can assist with technical sheets or sourcing.
✅ Next Steps:
-
Contact suppliers to confirm availability, freight, payment terms, and sample requests.
-
Request TDS/MSDS and performance data (e.g., TBN, Zn, P, Ca levels; engine tests like Mack T‑8, Caterpillar 1K).
-
Evaluate pricing vs MOQ to align with your blending needs.
-
Discuss regulatory compliance (e.g., REACH, ISO, NSF certifications) if required.
