    Default First Oil Change; use DC-4 or Not?

    EX-2 kit. Bought a Tempest AA48162 filter and took off the stock filter (Tempest AA48162) that came with the engine.

    The new filter states not to use any lubrication (DC-4 or oil) on the gasket prior to installation. The old stock filter specifically stated to use DC-4 or oil prior to installation. Same torque level on the filters.

    I searched the forum and the CC340 engine manual and didn't find anything.

    I have never installed an aircraft oil filter without using DC-4. Is this something specific to the filter or it's intended application other than the CC340?

    Is it recommended to use DC-4 or oil to lube the gasket before installation on CC340?
