PERFORMAX 15W40 is a heavy duty, low ash, shear stable 15W40 multigrade diesel engine oil. It has been formulated specifically to meet the requirements of US design emission engines such as Cummins which incorporate exhaust gas recycling (EGR). EGR can add to deposits forming in the combustion chamber, and therefore Performax’s 0.8% sulphated ash assists in maintaining engine and injector cleanliness.

PERFORMAX 15W40 meets or exceeds the following specifications.


* US MILITARY - MIL-L-2104E, MIL-L- 46152E.

* GENERAL MOTORS 6048M, 6G49M, 6085M.


* CUMMINS NTC 400 (0.8% sulphated ash)

* FORD ESE-M2C-1 53E, E8N-M2C-1 21 B

* ALLISON Type C-4 (SAE 30)

* DETROIT DIESEL Series 40, 50, 55, 60 engines

(Detroit Diesel do not endorse multigrade crankcase oils in two stroke engines)



PERFORMAX 15W40 is recommended for high speed, turbocharged four stroke engines, in particular US emission design engines. These include both pre and post 1994 engines, operating on low sulfhur fuels and especially high top ring designs which prefer low ash oils. Applications include long distance trucking, earthmoving, off-highway and stationery plant operations where engines are run under the most severe conditions and for the maximum oil change periods as recommended by the manufacturer.

PERFORMAX 15W40 is a low phosphorus oil suitable for all four stroke diesel and petrol engines making it ideal for mixed fleets of petrol and diesel engines where the diesel engines are predominantly US manufactured.

May be used in Allison (Type C-4, SAE 30) transmissions and in hydraulic systems where manufacturers' specifications permit.

PACKAGE SIZE 205 Litre, 60 Litre, 20 Litre, 5 Litre, 1 Litre.

PERFORMAX 15W40 meets the latest US diesel manufacturers specifications and API diesel and petrol engine classifications. As such it is ideal as a mixed petrol/diesel engine fleet oil where the diesel engines are predominantly of US manufacture.
