Gulfmar Select Plus is a premium quality multi-functional trunk piston engine oil designed for use in the latest highly rated medium speed diesel engines operating on residual fuels in marine, power generation and industrial applications. The advanced sludge control additive technology used in this oil meets the ever increasing demands of medium speed diesel engines and provides exceptional engine cleanliness and wear protection. This oil is available in SAE 30 & 40 viscosity grades with a TBN (Total Base Number) ranging from 20 to 55. Each grade has got a suffix of 3 digits in which the first digit indicates the SAE grade (eg. 3 indicates SAE 30 and 4 indicates SAE 40) and the last two digits indicate the TBN. These oils exhibit a high degree of water tolerance and have better water separation and base retention properties. These oils meet the performance requirements of API CF.
