Medium speed diesel engine oils to help operators with protection against oil stress, reduced lubricant deposits and extended oil life.
Shell Lubricants has launched medium speed diesel engine oils to help operators achieve high availability and reliability at the lowest possible running cost.
Formulated to cope with all levels of oil stress, the latest version of Shell Argina will provide operators with protection against oil stress, reduced lubricant deposits and extended oil life.
Bala Balachandran, Power Sector and Brand Manager for Shell Lubricants, said: "Modern diesel engines are designed to use less oil, while coping with long, continuous operational hours at high output".
"Although this can provide operators with high levels of productivity and efficiency, it places more demand on oil performance and results in oil stress".
"This can compromise engine performance by increasing the risk of accelerated component wear and failure".
Diesel engine oils are prone to three types of oil stress - acid, thermal and asphaltene.
Acid stress can lead to base number (BN) depletion and accelerated engine ring, liner and valve wear.
Thermal and asphaltene stress can cause oil viscosity increase and deposits on the piston undercrown and the ring groove.
Offering resistance to deposits at high and low temperatures, high BN retention and high resistance to viscosity increase, the Argina range will help operators reduce oil stress by improving engine cleanliness.
This helps to reduce piston wear, ring sticking, blow-by and liner damage resulting from deposit formation.
Furthermore, it will help reduce fuel pump sticking and crankcase fouling caused by asphaltene oil stress.
In developing Argina, accelerated engine tests, conducted at Shell's Marine and Power Innovation Centre in Hamburg, have demonstrated its ability to reduce piston undercrown deposits, with almost no deposits reported at the end of test cycles.
Shell's scientists also worked closely with OEMs, and field trials reconfirmed the performance benefits of Argina.
In these trials, high engine cleanliness was recorded both at hot spots, such as ring grooves and piston undercrown, as well as in colder areas, such as crank case and valve deck.
The oil range has been approved by OEMs including Wartsila, Caterpillar (Mak), Man B and W and Semt-Pielstick.
Balachandran said: "Diesel engines with low oil consumption can stress the oil to an extent where it has to be regularly replaced".
"This can prove costly for operators in terms of high oil consumption, maintenance hours and scheduled stoppages".
"Further costs can be incurred because of unscheduled stoppages, component wear and failure".
