Gulf Supreme Duty LE 15W-40 is an extra high-performance heavy-duty diesel engine oil specifically developed to extend engine life in the most severe duty on and off-highway applications. The advanced formulation technology of this product ensures exceptional performance in modern, high-output, low emission engines including those employing Exhaust Gas Recirculation (EGR) systems, as well as older engines operating on diesel fuel with low or high sulphur. It meets the latest performance requirements of major American and European OEMs.
Features & Benefits
- Exceptional thermo-oxidative stability reduces engine deposits, sludge build-up and oil thickening
- Outstanding soot handling capability minimises soot related viscosity increase and wear
- High shear stability maintains viscosity at elevated temperatures leading to improved wear protection and reduced oil consumption
- Superior protection against corrosive wear extends life of engine components
- Excellent TBN retention helps in countering harmful effects of corrosive exhaust gases and extending oil life
Applications
- Recommended for use in the latest turbocharged and low-emission high-performance diesel engines including those employing EGR and meeting US 2004 emission norms introduced in 2002
- Recommended for applications in:
1. On-highway trucking applications operating in high speed/high load and short haul pick-up/delivery vans
2. Off-highway equipment operating in severe low-speed/heavy load conditions including those used in
construction, mining, and agriculture - Also recommended for high-performance gasoline engines and mixed fleet operations
- Suitable for application requiring oils meeting API CI-4, CH-4, CG-4, CF-4 & CF performance levels
