Masterlube 30 – SAE 30 CF/SG

MASTERLUBE 30 has been formulated to lubricate turbo-charged and normally aspirated diesels operating under severe stress conditions in both on and off highway situations.The low phosphorous level and low sulphated ash content ensures its use for mixed fleet operators including those with petrol engines with catalytic convertors. MASTERLUBE 30 is suitable for marine applications calling for SAE 30 viscosity oils.


MASTERLUBE 30 is suitable for the lubrication of all types of trucks, earthmoving equipment, stationary engines, cars and light commercials where a CF diesel rating or a SG petrol rating is required and for marine applications calling for SAE 30 viscosity oils.

MASTERLUBE 30 is suitable for US diesel truck engines up to 1990, Japanese and European diesel trucks, leaded or unleaded petrol engines and LPG fuelled engines. Its low phosphorous content protects the life of catalytic convertors and its low ash content prevents injector fouling.


MASTERLUBE 30 meets or exceeds the following specifications:

  • MIL-L-46152E/2104C
  • CCMC G4/D4/PD2
  • Daimler Benz DB 227.1


MASTERLUBE 30 meets the requirements of a CF/SG engine oil. It provides a high level of protection against wear, sludge formation and acid corrosion.

MASTERLUBE 30 also assists in maintaining engine cleanliness and extending the life of all moving parts subject to wear.
