PEAK PERFORMANCE DIESEL 15W40 is a high-performance, heavy-duty, mixed fleet automotive engine oil.
It is formulated for use in a wide range of Japanese and pre 1999 US and European diesel engines requiring
API CH-4 performance, both naturally aspirated and turbocharged.

PEAK PERFORMANCE DIESEL 15W40 is an excellent mixed fleet lubricant, suitable to be used for long-distance
trucking, off-highway and earthmoving applications, stationary plants, agricultural tractors, farm machinery,
stationary generator sets, and high-speed diesel engines in marine service. It can also be used in many
passenger cars, light commercial, and truck petrol engines operating in all service conditions.

PEAK PERFORMANCE DIESEL 15W40 can be used in non-engine applications such as powershift transmissions
and mobile hydraulic systems where engine oils SAE 15W/40 API CH-4 are specified.

PEAK PERFORMANCE DIESEL 15W40 protects against the formation of gums and varnish at elevated
temperatures through good oxidation stability. The multi-grade viscosity of PEAK PERFORMANCE
DIESEL 15W40 protects against wear at start-up and under high temperature operating conditions, and proven
anti-wear additives are used to provide excellent protection against the wear of critically loaded components. High
temperatures are encountered in turbocharged diesel.
