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.
