A range generation of lubricants for medium-speed engines running on heavy fuel oils

Aurelia XL has been specially formulated using the latest additive technology demanding environment of the latest marine engines. It has been formulated and tested to have industry leading performance in the following areas: compatibility with residual fuel of different qualities leading to excellent engine cleanliness in both the hot and cold areas of the engine, good high temperature thermal and oxidation stability, low volatility, high load carrying capacity and excellent corrosion protection.

Benefits of Aurelia XL

Lower maintenance costs

Aurelia XL’s superior clean formulation reduces oil consumption by maintaining the ring pack in good condition.

Cleaner crankcases, cam boxes and rocker arms reduce the cleaning required during maintenance operations.

The new clean formula reduced ring sticking and breakage, which contributes to a longer engine life.

Superior protection of all engine parts against corrosion due to Aurelia XL high BN leads to longer component life and longer service intervals.

Aurelia XL’s exceptional resistance to oxidation and thermal break down reduces oil viscosity increases leading to an improvement in lubricants life.

Greater engine reliability

Due to the advanced formula of Aurelia XL your engine will remain cleaner and piston ring belt, cylinder liners and piston under crown deposits (piston cooling gallery) will be reduced. This will lead to greater engine reliability, especially in high stress of engine overload conditions.

Designed and tested for the following applications

Aurelia XL has been developed for use in medium speed main propulsion and auxiliary trunk piston diesel engines in both marine and power plant applications. It is also suitable for use in turbochargers, geared transmissions, oil filled stern tubes and variable pitch propellers and other deck equipment requiring a SAE 30 or 40 grade oil.

Aurelia XL: Main features benefits

Detergency: Keeps the hot part of the engine clean. Reduces built up of deposits on piston rings and piston under crowns and purifier pre-heaters.

Dispersancy: Keeps the cold part of the engine clean reduces the built up of “black paint” or sludge in the crankcase, rocker area and cam box.

Fuel compatibility: Resists the effects of contamination with residual fuel, avoids the formation of black sludge and asphaltenic residues. Helps fuel pump reliability.

Thermal stability: Maintains lubricants performance and avoids increases in viscosity.

Anti-oxidation: Resists the oxidation attack thus avoiding the formation of lacquers and deposits and oil degradation.

Alkalinity reserve (BN): Prevents corrosive wear by rapidly neutralizing the acids formed by the burning of high sulphur fuel.

Extreme pressure anti-wear: Guarantees the presence of a lubricating film, even at high pressure. Reduces engine component wear.

Demulsibility - filterability: Guarantees the easy elimination of water in the case of salt or fresh water contamination. Facilitates easy filtration and the elimination of insoluble contaminants.

Resistant to hydrolysis: The lubricant maintains its performance characteristics after separation from water.

Anti corrosion: Maintains engine part in good condition leading to long engine life.

Aurelia XL

An insurance policy for your engine

Aurelia XL has been formulated with an extra safety margin to ensure that it exceeds the requirements of today’s highly rated engines and that will meet the requirements of tomorrow’s engine designs.

The product has undergone extensive in house laboratory bench and engine tests plus a full set of in service trials to prove its superior performance.

Aurelia XL has been approved by all major diesel engine OEMs following extensive field engine tests.

Available range

Aurelia XL is available in SAE 30 and 40 grades and in a range of BN’s with the major grades being BN 30 BN40 and BN55. For special applications BN 25 and BN 65 grades are also available.
