Engineered specifically to survive high ambient temperatures, heavy payload demands, and elevated soot levels in Indonesian fleet operations.
Technical Insights into Thermal Degradation, Biodiesel Compatibility (B35/B40), and Freight Logistics Optimization in East Java
As Indonesia's second-largest metropolis and the primary maritime gateway for Eastern Indonesia, Surabaya (East Java) operates under rigorous logistics dynamics. Anchored by the Port of Tanjung Perak and connected via the Trans-Java Toll Road, heavy-duty commercial trucks, inter-island freight barges, and industrial generators run continuously under severe tropical climates.
Operating heavy machinery in Surabaya presents distinct tribological challenges: ambient temperatures averaging 32°C to 35°C, high relative humidity (up to 85%), and stop-and-go congestion surrounding industrial zones like Rungkut (SIER) and Gresik. Lubricants without high thermal-viscosity stability rapidly undergo thermal oxidation, leading to premature shear breakdown, oil thickening, and carbon deposit buildup on piston skirts.
Indonesia's national mandate enforcing B35 Biodiesel (35% Palm Oil Fatty Acid Methyl Ester blended with diesel)—moving rapidly toward B40—fundamentally changes lubricant chemistry requirements. Biodiesel blends exhibit higher boiling points, leading to unburnt fuel accumulating in the oil sump (fuel dilution).
This causes rapid Total Base Number (TBN) depletion, oil nitration, and severe sludge accumulation. Enterprise fleet managers in Surabaya require advanced heavy-duty diesel oils engineered with robust alkalinity reserve (high TBN), superior ash dispersancy, and oxidation inhibitors designed to neutralize acidic combustion byproducts resulting from biodiesel use.
| API Specification | Primary Application Field | TBN (mg KOH/g) | Soot & Oxidation Control | Biodiesel (B30-B40) Suitability |
|---|---|---|---|---|
| API CF-4 | Older heavy-duty logistics trucks & agricultural engines | 8.0 - 10.0 | Standard protection against high-temp deposits | Moderate (Requires shorter drain intervals) |
| API CH-4 | High-speed, 4-stroke heavy diesel engines (Naturally aspirated & turbocharged) | 9.5 - 11.5 | Enhanced wear protection & valve train durability | Good (Standard industrial fleets) |
| API CI-4 PLUS | EGR-equipped heavy trucks, long-haul Trans-Java shipping fleets | 11.0 - 13.5 | Superior soot dispersancy & shear viscosity retention | Excellent (Resists fuel dilution & corrosion) |
| API CJ-4 / CK-4 | Modern low-emission engines with DPF/SCR, premium container haulers | 10.0 - 14.0 | Advanced low-SAPS formula, extreme high-temp shear stability | Maximum (Optimized for modern bio-diesel blends) |

Founded in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech manufacturing enterprise integrating scientific R&D, synthetic blending, and worldwide export distribution. Operating across a modern 131-acre manufacturing campus with an annual capacity exceeding 200,000 metric tons, Longhai delivers high-grade lubrication solutions to over 139 cities and global international markets.
Longhai operates its flagship proprietary brand "Century Longhai" alongside strategic international collaborations such as the British "A Ba" series. To ensure absolute customer confidence, our lubricant product range is underwritten with quality liability insurance by PICC (People's Insurance Company of China).
Our manufacturing ecosystem strictly adheres to international quality protocols. Longhai is certified under ISO 9001:2015 (Quality Management System), ISO 14001 (Environmental Management System), and ISO 45001 / OHSAS 18001 (Occupational Health & Safety). Furthermore, our specialized formulations have attained prestigious OEM approvals, including Mercedes-Benz Automatic Transmission Certifications.
Unlocking Maximum Operational Cost-Efficiency for Business Buyers Serving Surabaya & East Java
Utilizing high-precision automated metering lines, Longhai maintains blending accuracy within 1‰–2‰. This computerized process accelerates filling speed by 20% to 35%, ensuring rapid lead times for volume bulk shipments destined for Surabaya port.
We customize additives (viscosity index improvers, anti-foam agents, and detergent-dispersant packages) specifically for tropical climate endurance and high-sulfur or biodiesel fuel environments prevalent in Indonesian industrial logistics.
From bottle molding design, customized drum branding, to precise lab testing verification, our OEM team empowers Surabaya distributors to build high-margin private label lubricant brands backed by international quality standards.
Viscosity, API grade, OEM specs, and volume requirements.
Lab verification tailored to Surabaya operating environment.
Dispatching physical samples for ASTM laboratory analysis.
Automated filling, export palletization, and shipping to Surabaya.
Targeted Lubrication Engineering for Diverse Industrial Operations in the Surabaya Economic Zone
Heavy container reach stackers, yard tractors, and terminal cranes operating at Tanjung Perak Port demand oils with extreme shear stability. Our API CI-4 PLUS and CJ-4 synthetic oils prevent hydraulic valve sticking and engine wear under 24/7 continuous idling and heavy lifting cycles.
Commercial logistics fleets running along the Trans-Java toll road connecting Surabaya, Semarang, and Jakarta require long drain interval (LDI) lubricants. High thermal stability reduces oil consumption and protects turbochargers against severe soot-induced abrasion.
Tugboats and inter-island transport vessels navigating the Madura Strait demand diesel oils with superior water tolerance, anti-rust properties, and robust TBN reserves to neutralize marine fuel sulfur deposits.
