API CJ-4 Diesel Engine Oil Manufacturer & Global Exporter — DANA Lubes, UAE

DANA Lubes is a certified API CJ-4 diesel engine oil manufacturer based in Dubai, UAE, supplying heavy-duty diesel engine oils in SAE 15W40, 10W30, and 20W50 viscosity grades to fleet operators, distributors, and OEM-authorized service networks across 70+ countries. Our CJ-4 formulations meet strict low-SAPS limits — sulfated ash ≤ 1.0%, phosphorus ≤ 0.12%, sulfur ≤ 0.4% — and are engineered for long drain intervals in modern emissions-controlled diesel engines. Export is handled direct from danalubes.com via Jebel Ali Port in 20L, 60L, 208L drums and 1,000L IBC totes.

What API CJ-4 Means Technically

API CJ-4 is the heavy-duty engine oil (HDEO) service category introduced in 2006 to address the performance demands of diesel engines equipped with exhaust aftertreatment systems — specifically diesel particulate filters (DPF) and diesel oxidation catalysts (DOC). Oils certified to API CJ-4 must pass a defined suite of ASTM and SAE bench and engine tests, and must not exceed the following chemical limits:

These SAPS limits are not arbitrary — high sulfated ash loading is the primary cause of DPF blockage and catalyst poisoning. By capping ash, phosphorus, and sulfur, API CJ-4 oils extend aftertreatment system service life and protect EPA 2007+ and Euro V/VI emission compliance. DANA Lubes blends its CJ-4 line using Group II+ and Group III base stocks combined with a low-SAPS DI (detergent-inhibitor) additive package to deliver the full performance profile without compromising aftertreatment hardware.

DANA CJ-4 Engine Oil Product Lineup

Our API CJ-4 product range covers the full viscosity spread required by modern HDEO specifications, from cold-climate multi-grade 10W30 to high-load 20W50 for extreme ambient temperatures common in GCC, African, and South Asian markets.

All three grades carry backward compatibility with API CI-4 Plus and CH-4, making them drop-in replacements for older fleet assets still running pre-2007 diesel engines. View our bulk supply options and MOQs for each grade.

OEM Approvals & Industry Endorsements

API CJ-4 certification alone is the floor, not the ceiling. Fleet procurement teams frequently specify additional OEM approvals before tendering bulk lubricant contracts. DANA Lubes SAE 15W40 CJ-4 meets or is formulated equivalent to the following OEM performance specifications:

• Cummins CES 20081 — Required for ISX, ISB, ISC, and ISL engines. Targets extended drain intervals up to 60,000 km in on-highway applications.
• Caterpillar ECF-3 — CAT’s proprietary engine cleanliness and oxidation stability benchmark for C-series and ACERT engines used in mining and construction.
• Detroit Fluid Specification DFS 93K222 — Covers Detroit Diesel DD13, DD15, and DD16 engines in heavy haulage applications.
• Volvo VDS-4 — Volvo Drain Specification targeting piston cleanliness, wet clutch compatibility, and liner wear in FH, FM, and FMX truck series.
• MB 228.31 — Mercedes-Benz approval for OM400 and OM900 series heavy-duty engines.

These approvals confirm that DANA Lubes CJ-4 formulations are not generic API-licensed blends — they are engineered to pass the specific soot dispersancy, piston deposit, and wear tests each OEM mandates before endorsing a lubricant for factory-fill or service-fill use.

Applications: Where API CJ-4 CJ4 Engine Oil Is Required

Long-Haul Trucking & Fleet Operations

SAE 15W40 CJ-4 is the dominant viscosity grade for on-highway fleets. Long-haul operators running Cummins, Volvo, or Mercedes-Benz platforms under high-mileage duty cycles require a formulation that retains TBN (Total Base Number) above 4 mg KOH/g through extended drain intervals. DANA Lubes CJ-4 is formulated with an elevated TBN reserve (starting TBN: 12.0 mg KOH/g) specifically to sustain neutralization capacity against combustion acids over 15,000–20,000 km drain periods on ULSD fuel.

Mining & Quarrying Equipment

Haul trucks, hydraulic shovels, and drill rigs operate under sustained high-load cycles that generate elevated soot and thermal stress. API CJ-4 SAE 20W50 delivers the film strength and oxidation stability these conditions demand. The low-ash formulation is critical for engines fitted with closed-loop crankcase ventilation — excess ash deposits in the CVS system cause pressure build-up and accelerated liner wear.

Construction Machinery

Excavators, motor graders, and bulldozers typically use multi-brand engine platforms — Caterpillar, Komatsu, John Deere, Liebherr — each with its own oil specification. API CJ-4 with ECF-3 and VDS-4 credentials provides a single approved lubricant that satisfies mixed-fleet procurement, reducing SKU count and inventory complexity on large construction sites.

Power Generation & Stationary Engines

Diesel gensets operating on ULSD in telecom tower sites, data centers, and industrial facilities benefit from CJ-4’s soot control and acid neutralization chemistry, particularly in locations where extended service intervals between oil changes are operationally necessary.

API CJ-4 and TBO Management: Why TBN Retention Matters

Total Base Number (TBN) is the most actionable metric for fleet TBO (Time Between Overhauls) management. TBN measures the oil’s remaining acid-neutralization capacity — as it drops toward 2.0 mg KOH/g, the oil is no longer protecting engine components from acidic corrosion. Sulfur in diesel fuel accelerates TBN depletion; ULSD (<15 ppm sulfur) significantly extends drain intervals compared to higher-sulfur fuels used in some export markets.

DANA Lubes CJ-4 15W40 is formulated with a starting TBN of 12.0 mg KOH/g, providing a practical drain interval of 15,000–20,000 km on ULSD, or 8,000–12,000 km on 500 ppm sulfur diesel, subject to on-site used oil analysis confirmation. Procurement managers running oil analysis programs (Spectro, Polaris Labs, or in-house FTIR) should use these figures as baseline targets for initial sample intervals.

Frequently Asked Questions — API CJ-4 Engine Oil

What is the difference between API CJ-4 and CK-4 engine oil?

API CK-4 (introduced 2016) supersedes CJ-4 and adds tighter oxidation stability, shear stability, and aeration control requirements. CK-4 is backward compatible — it can replace CJ-4 in older engines. However, many OEMs in developing markets still specify CJ-4 as the minimum accepted grade, and CJ-4 certified oil remains widely available and cost-effective for fleets not requiring CK-4 performance. DANA Lubes supplies both categories; contact us to confirm which grade your engine OEM mandates.

Can API CJ-4 oil be used in engines that require API CI-4 Plus?

Yes. API CJ-4 is fully backward compatible with CI-4 Plus, CI-4, CH-4, and CG-4 service categories. Fleet managers running mixed fleets with both older and newer diesel engines can standardize on a single API CJ-4 grade to cover all assets, provided the viscosity grade matches each engine manufacturer’s specification.

What is the minimum TBN for API CJ-4 certified oil?

API CJ-4 does not mandate a minimum fresh TBN value in its specification. However, most OEM service fill approvals (Cummins CES 20081, Volvo VDS-4) require a starting TBN of at least 10.0 mg KOH/g (ASTM D2896) to support target drain intervals. DANA Lubes CJ-4 15W40 ships with a starting TBN of 12.0 mg KOH/g.

What is the MOQ for bulk API CJ-4 export from UAE?

DANA Lubes accepts bulk CJ-4 orders from 200L (one drum) for distributor sampling, with standard export MOQs starting at one 20-foot container (approximately 18,000L in 208L drums). IBC and flexi-tank bulk orders have separate MOQ tiers. Get a CFR quote by contacting our export desk via WhatsApp or email.

Does DANA Lubes supply API CJ-4 with private label / white label packaging?

Yes. DANA Lubes provides full private label production for API CJ-4 diesel engine oil from a minimum of 5,000L per SKU. This includes custom label design, SDS and COA documentation in the buyer’s language, and compliance documentation for the destination country.
