Clean-burning, high-cetane diesel meeting EN 590 specifications with maximum 10 mg/kg sulfur content. Designed for Euro 5 and Euro 6 engines with DPF, SCR, and DOC aftertreatment systems.
Ultra-Low Sulfur Diesel (ULSD) at 10 ppm is the gold standard for automotive diesel in the UAE and globally. It is the mandatory fuel for all modern on-road diesel vehicles equipped with DPF, SCR, and DOC emission control systems.
ULSD is not just "cleaner diesel" — it's an enabling technology. Without it, the advanced emission control systems that reduce particulate matter by 99%+ and NOx by 90%+ simply cannot function. Using higher-sulfur diesel in a Euro 5/6 vehicle will poison the catalyst, clog the DPF, and cause thousands of dirhams in damage.
Important: Using diesel above 10 ppm in any vehicle with DPF or SCR will cause damage. DPF replacement: AED 8,000–25,000 per vehicle. SCR catalyst: AED 5,000–15,000+. Injector set for 6-cylinder: AED 9,000–24,000 in parts alone.

Sulfur in diesel damages modern aftertreatment systems and engine components in multiple ways:
High-sulfur fuel produces sulfate particulates that cannot be burned off during regeneration — they accumulate permanently, clogging the filter. DPF replacement typically costs AED 8,000–25,000 per vehicle.
Sulfur poisons the SCR catalyst permanently, reducing its ability to convert NOx. SCR catalyst replacement: AED 5,000–15,000+. AdBlue/DEF consumption increases dramatically with poisoned catalysts.
Modern common-rail injectors operate with micron tolerances. Sulfur compounds cause deposit formation, spray pattern distortion, power loss, and increased fuel consumption. Single injector: AED 1,500–4,000. 6-cylinder set: AED 9,000–24,000 in parts alone.
Sulfur accelerates wear in precision pump components. Pump failure often sends metal particles through the entire fuel system — requiring replacement of pump, injectors, fuel rail, and complete system flushing.
10 ppm diesel produces 99%+ less SO₂ than 500 ppm diesel — a major contributor to acid rain and respiratory illness. ULSD enables DPF function (99%+ PM reduction) and SCR function (90%+ NOx reduction).
UAE mandates ≤10 ppm sulfur for on-road diesel (Euro 5/6 equivalent). Using non-compliant diesel can result in vehicle impoundment at RTA inspection, warranty voiding, and potential fines for commercial operators.
Euro 5/6 trucks, delivery vans, coach buses, minibuses. With DPF+SCR, these engines achieve near-zero particulate emissions when supplied with ULSD.
Stage V / Tier 4 Final excavators, wheel loaders, bulldozers — from 2019+ with built-in DPF systems. ULSD is mandatory to maintain emissions compliance.
Modern diesel generators in hospitals, data centers, and commercial buildings increasingly come with emission control systems requiring 10 ppm fuel.
