Gulf Supreme Duty XLE series are extra high performance diesel engine oils specially developed for use in modern, high-output, low emission engines meeting US 2007 on-highway exhaust emission standards. These oils not only address the unique needs of these new engines and enhances the life of exhaust after treatment devices but also provides improved protection to older engines. These are formulated with state-of-the-art additive technology and severely hydroprocessed base oils to provide outstanding performance and overall protection. It exceeds the performance requirements of API CJ-4 and major global OEMs

ACEA E9, Cummins CES 20081, MAN M 3575, CAT ECF 3, ECF 2 and ECF1a, API CJ-4, Volvo VDS-4/ Mack EO-O PP/ Renault VI RLD-3 approval, MB-Approval 228.31, MTU Oil Category 2.1

• Latest high performance low emission engines including those equipped with DPF and Exhaust Gas Recirculation (EGR) and meeting US 2007 on-highway exhaust emission standards
• On-highway vehicles and off-highway equipments operating in severe low speed/heavy load conditions using either low (500 ppm) or ultra low (15 ppm) sulphur fuels
• High performance gasoline engines and mixed fleet operations requiring oils meeting API CI-4 PLUS, CI-4, CH-4, CG-4 CF-4, SN (5W-40 & 10W-40), SM, SL and SJ performance levels

• Outstanding thermal and oxidative stability reduces low-temperature sludge build-up, high-temperature deposits and oil thickening
• Excellent soot handling minimizes soot related viscosity increase and leads to longer engine/oil life
• Exceptional TBN retention resists harmful effects of corrosive exhaust gases and extends oil life
• Outstanding corrosive and abrasive wear protection extends life of engine components
• Low ash content reduces particulate build-up in Diesel Particulate Filter (DPF) and enhances its life
