Description and Application

This range comprises of a series of highly alkaline diesel –engine oil formulated from specially selected base oils with an additive combination providing high levels of detergency, dispersancy, oxidation resistance, gear protection and rust prevention. The oil is intended for the crankcase and cylinder lubrication of medium speed trunk –piston diesel engines operating on high –sulphur residual or distillate fuels. Selection of the most suitable grade for any specific application is influenced by severity of its operating conditions, but the general rule is to select the oil with the lowest initial TBN that will give an acceptable stabilized TBN in continuous service. Alternatively some engine manufacturers recommend selection of oil TBN according to the sulphur level of the fuel in use. It is recommended that ALMA303/304/403/404/405 is continuously centrifuged and /or filtered in accordance with the manufacturer’s instructions. Additionally it is important that engine manufacturers’ oil change intervals be observed. ALMA303/304/403/404/405 meets requirements of API CD

Main Features

• High level of engine cleanliness and minimum piston deposits.
• High thermal and oxidation stability to prolong service life.
• High alkalinity to neutralize the acidic products of combustion.
