10. Fluids and Ambient Temperature: Fuel, Lubricant and
Coolant
10.1 Overview
C NOTICE! If you do not use recommended fluids it may result in engine
damage.
The quality of fluids used in an engine can have a significant effect on the engine
performance and durability. You must select fluids appropriate for the engine and the climatic
conditions in which the equipment is to be used. The JCB EcoMAX engine has been
developed to operate using particular quality fuels, lubricants and coolant. If you use other
fluids then you must consult JCB Power Systems Applications department confirm that they
are acceptable.
10.2 Fuel
See the Engine Operator’s Manual for a statement on preferred fuels.
10.3 Lubricant
See the Engine Operator’s Manual for a statement on preferred lubricants.
You must select the lubricant viscosity based on the lowest ambient temperature at which
the equipment is started and the maximum ambient temperature at which it operates. Table
1 gives guidance on suitable oils for ambient temperature ranges.
You must change the oil and the oil filter at the specified service intervals. For oil change
intervals refer to the Service Manual. The oil filters installed with the flange facing
downwards.
Do not allow oil to come into contact with the FEAD belt.
