Outstanding Residual Fuel Compatibility

High performance additive detergent technology provides outstanding fuel-lube compatibility — reducing sludge formation from asphaltene contamination and enabling longer oil life in residual-fuelled medium-speed engines.

Excellent Engine Cleanliness

Reduced deposits in piston undercrown and ring belt areas — keeping crankcase, camshaft and piston areas clean for extended periods between overhauls in the most severe residual-fuelled medium-speed applications.

High Performance Thermal & Oxidation Stability

Excellent TBN retention and resistance to viscosity increases over long operating periods — maintaining consistent engine protection through extended drain intervals in severe service medium-speed marine diesel applications.

Excellent Lube-Fuel Compatibility

Compared to other medium-speed engine oils, excellent lube-fuel compatibility and easy water separation — critical for vessels operating on a range of residual fuel qualities through different ports.

ExxonMobil Patented DAC Test

Developed using ExxonMobil's patented DAC (Detecting Asphaltene Contamination) test — which checks lubricant samples for asphaltene contamination that, left undetected, could lead to piston damage and excessive oil consumption.

Rust & Corrosion Protection

Outstanding rust and corrosion protection — protecting critical wear surfaces from water and acidic corrosion in residual-fuelled medium-speed engines operating in the marine environment.

Deep-Sea Vessel Main Propulsion

Main propulsion and auxiliary engines on deep-sea vessels — bulk carriers, tankers, container ships and cargo vessels with medium-speed trunk piston engines running on residual fuels.

Coastal & River Ships

Main propulsion engines on coastal and river ships operating in South African coastal waters — particularly vessels calling at Cape Town, Durban, Saldanha and Port Elizabeth.

Stationary Power Plants

Medium-speed stationary diesel engines in power generation and industrial applications where 30 TBN residual fuel engine oil performance is required.

FPSO & Offshore Power

Medium-speed diesel generator engines on FPSOs and offshore platforms operating on HFO — where 30 TBN trunk piston engine oil performance is required for continuous duty power generation.
