Mobilgard™ ADL 40 — High-BMEP Medium & High-Speed Marine Engine Oil

Mobilgard™ ADL 40 — High-BMEP Medium & High-Speed Marine Engine Oil

Mobil · Mobilgard™ Marine · Authorised Distributor — South Africa

Mobilgard™ ADL 40 is a high performance, increased dispersancy SAE 40 engine oil designed for high Brake Mean Effective Pressure (BMEP) medium and high-speed diesel engines operating on distillate and MDO fuels. Specifically developed to combat liner lacquering, piston ring groove deposits and bore polishing in modern high-BMEP engines — it was selected by ExxonMobil to lubricate the world's largest plug-in battery hybrid ship, Color Hybrid, and its Rolls-Royce Bergen B33:45L diesel engines. The balanced formulation with superior load carrying properties also makes it suitable for marine gearing applications. Available through Orbit Industrial — authorised Mobil distributor, South Africa.

Features & Benefits

Combats Liner Lacquering & Bore Polishing

Specifically developed to reduce liner lacquering, piston ring groove deposits and bore polishing in modern high-BMEP engines — extending overhaul intervals and reducing liner wear costs in high-output distillate-fuelled marine diesels.

Increased Dispersancy Technology

High dispersancy formulation keeps combustion by-products in suspension — preventing the sludge and varnish formation that leads to ring sticking, increased oil consumption and reduced engine efficiency in high-BMEP engines.

Superior Load Carrying — Also Suitable for Gearing

Superior load carrying properties minimise piston ring and liner wear — and also make Mobilgard ADL 40 suitable for use in marine gearing applications, simplifying lubricant management on vessels with integrated engine and gearbox lubrication.

Enhanced Engine Cleanliness

Reduces oil consumption and increases time between engine overhauls — helping reduce total vessel operating costs and maintenance frequency in high-BMEP medium and high-speed propulsion engines.

Hybrid Vessel Compatible

Proven on Color Hybrid — the world's largest plug-in battery hybrid ship — in Rolls-Royce Bergen B33:45L engines operating in hybrid propulsion mode where engine starts, stops and load variations place unique demands on the lubricant.

Compatible with Distillate & MDO

Formulated for engines operating on marine distillate (MGO/MDO) and compliant with IMO low-sulphur fuel requirements — suitable for vessels operating under ECA emission control area regulations.

Recommended Applications

High-BMEP Medium-Speed Engines

Rolls-Royce Bergen, MAN ES and Wärtsilä high-BMEP medium-speed marine diesel engines operating on distillate fuels — where conventional trunk piston engine oils are inadequate for severe service demands.

Ferries & Passenger Vessels

High-speed ferries and passenger vessels with high-BMEP propulsion engines operating on MGO/MDO under ECA regulations — where engine cleanliness and extended overhaul intervals are critical to schedule reliability.

Hybrid & Dual-Fuel Vessels

Hybrid propulsion vessels with diesel-electric systems and frequent engine cycling — proven in the world's largest hybrid ship where variable load operation demands exceptional dispersancy and deposit control.

Marine Gearing

Also suitable for marine gearing applications — simplifying lubricant inventory on vessels where a common engine and gearbox oil specification reduces the number of products managed onboard.
