🛢️ General Internal Combustion TBN190 Engine Oil Compound Additive
“The Key to Improving Performance and Extending Service Life”
🔍 Overview
The TBN190 engine oil compound additive is a high-base-number multifunctional additive package, designed for internal combustion engines, especially diesel and gasoline engines that operate under high thermal stress, long drain intervals, or low-SAPS requirements.
- TBN (Total Base Number): 190 mg KOH/g
- Function: Neutralizes acids, disperses soot, protects metal surfaces, and improves oil stability.
✨ Key Functions
| Function | Description |
|---|---|
| 🧼 Detergency | Keeps engine parts clean by preventing deposit formation |
| ⚙️ Dispersancy | Suspends soot and sludge particles in oil to prevent agglomeration |
| 🛡️ Anti-corrosion | Neutralizes acidic combustion byproducts (thanks to high TBN) |
| 🔧 Anti-wear | Forms protective films to reduce metal-to-metal contact |
| 🌡️ Oxidation Resistance | Slows down oil degradation at high temperature |
🔬 Typical Composition (Reference Formula)
| Component | Purpose |
|---|---|
| High-base sulfurized calcium alkyl phenate | Main TBN contributor, anti-corrosion and detergent |
| Calcium sulfonate (overbased) | Strong detergent and acid neutralizer |
| Polyisobutylene succinimide (PIBSI) | Ashless dispersant |
| Zinc dialkyldithiophosphate (ZDDP) | Anti-wear and antioxidant |
| Phenolic or aminic antioxidant | Long-term oxidation stability |
| Pour point depressant (optional) | Enhances low-temp performance |
⚙️ Performance Benefits
| Feature | Advantage |
|---|---|
| ✅ High TBN (190) | Ideal for fuel with high sulfur content or long oil drain intervals |
| ✅ Long-lasting protection | Maintains alkalinity longer than conventional TBN 100–130 additives |
| ✅ Enhanced engine cleanliness | Particularly important in EGR or turbocharged engines |
| ✅ Versatility | Can be blended into CI-4, CH-4, CK-4, or even CF grade formulations |
| ✅ Extended service life | Reduces frequency of oil changes and wear-related failures |
🔧 Application Areas
| Equipment | Usage |
|---|---|
| 🚛 Diesel trucks | Long-drain oils for heavy-duty transport |
| 🏭 Generators | Especially in remote or offshore power stations |
| 🚜 Agricultural & construction equipment | Operates under high load and contamination risk |
| 🚗 Passenger cars (diesel/gasoline) | With tailored low-SAPS variants |
| 🛳️ Marine engines | Medium-speed engines using HFO or low-grade fuel |
📦 Typical Usage Rate
| Product Type | Treat Rate |
|---|---|
| HD diesel engine oil (e.g., SAE 15W-40) | 7–12% |
| Gasoline engine oil (SAE 10W-30) | 5–8% |
| Marine oils / high sulfur fuel | Up to 15% (formulation dependent) |
⚠️ Formulation Tips
- High TBN additives may cause ash buildup in DPF-equipped engines — for these, a low-ash or mid-TBN alternative is better.
- Ensure base oil compatibility with calcium sulfonates and phenates (especially in Group II & III).
- Adjust ZDDP and dispersant levels to maintain oxidation control and wear protection balance.
The TBN190 compound additive is a high-performance solution for formulating premium engine oils that offer extended life, outstanding cleanliness, and protection under the most demanding conditions. It is a key enabler in modern, long-drain lubricants for internal combustion engines.
General internal combustion engine oils with a Total Base Number (TBN) of 190 are designed to offer superior alkalinity reserve to neutralize acidic combustion by-products and extend the service life of the engine oil. These high TBN engine oils are particularly beneficial for heavy-duty applications and engines operating under severe conditions where increased protection against corrosion, oxidation, and wear is required. The choice of compound additives plays a crucial role in enhancing the performance and longevity of these specialized engine oils.
TBN and its Importance:
- TBN is a measure of an oil’s ability to neutralize acids produced during engine combustion.
- Engine oil degrades over time due to heat and exposure to combustion byproducts like acids. These acids can cause corrosion, sludge buildup, and increased wear.
- Higher TBN oils can neutralize more acid, potentially extending oil change intervals and reducing wear.
TBN 190 for General Engines:
- TBN 190 might be suitable for some high-performance engines or those operating under severe conditions where high acid production is expected.
- For many typical gasoline engines, a TBN of 190 may be overkill. Standard engine oils typically have a TBN between 8 and 12.
Other Factors for Performance and Service Life:
- Viscosity: The correct viscosity oil for your specific engine is crucial for optimal performance and wear protection. TBN is not a substitute for proper viscosity.
- Friction Modifiers and Other Additives: Modern engine oils contain a variety of additives that improve performance and protect the engine in various ways. A single TBN additive likely wouldn’t address all these aspects.
- Oil Base Stock: The quality of the oil’s base stock (synthetic vs. conventional) significantly impacts performance and service life.
Formulating high TBN engine oils requires a balanced combination of compound additives to ensure optimal performance, protection, and longevity of the engine and its components. The choice of additives plays a crucial role in enhancing the oil’s alkalinity reserve, oxidative stability, wear protection, and corrosion resistance, thereby extending the service life of the engine oil and ensuring reliable performance under severe operating conditions.
When selecting compound additives for high TBN engine oils, it’s essential to consider factors such as the specific requirements of the application, compatibility with other additives, and compliance with industry standards and specifications to ensure optimal performance and reliability.
