Engine Description
Expected engine life is predicted by the average
power that is demanded. The average power that is
demanded is based on fuel consumption of the
engine over a time. Reduced hours of operation at
full throttle and/or operating at reduced throttle
settings result in a lower average power demand.
Reduced hours of operation will increase the length
of operating time before an engine overhaul is
required.

Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or
consumables (filters, additives, catalysts) which are
made by other manufacturers are used on Perkins
products, the Perkins warranty is not affected simply
because of such use.
However, failures that result from the installation
or use of other manufacturers devices,
accessories, or consumables are NOT Perkins
defects. Therefore, the defects are NOT covered
under the Perkins warranty.
