Re: How do I clean an oil bath air filter?

If you have the time it can't hurt to soak it in varsol or kerosene overnight or even longer. Then swish it around a little, take it out and let it drip dry over a drip pan. Finally pour a little oil in to dampen the fibres.

Not sure about Packard but Chrysler used to recommend 50 wt oil. If this is not available Walmart sells straight 30 4 stroke lawn mower oil.

You don't need to clean out the bottom pan until it is half full of dirt. Just top it up to the level line.

If it has too much dirt, you take it off and pour out the oil, and wipe out the sludge with rags or cotton waste. Give it a final wipe with a rag dampened in varsol.

In today's driving conditions it should stay good for years. In the old days of dirt roads they had to service the filters more often, in real dirty conditions they recommended daily servicing.
