Wet or Dry Bath Oil Filters?

Wet or Dry Bath Oil Filters?

Oil bath filters are effective at removing dust and dirt from the air used by the engine.  If the oil bath filter was really effective then why did the automotive industry give it up for most if not all applications? Was it just too messy or not green enough for today’s world?

Which version you choose is not really all that important as both filters work very well under most situations. It’s a personal choice that has no visible impact on the jeep.   It’s a great idea and can be environmentally friendly for all you tree huggers out there.

Some of these folks that pooh pooh the dry air filter are the same ones that tell you to use silicone in the brakes. One modern idea is bad, the other isn’t? Neither one can be seen.

Don’t try doing this with an oil bath filter! Your jeep fender will get an oil bath.

Besides if I spill my dry air filter on the fender it doesn’t leave any trace. Trying doing that with a loaded cuppa oil.

I’ve been running my dry air filter for 25 years and it works great. Why did I do it? Well, because I used to drive my jeep in sub-zero weather. You can’t have oil in the oil bath filter in sub-zero weather. You are supposed to drain it and run with it dry. How effective can that be? So I converted and haven’t looked back.

The dry filter cartridge easily goes into the canister with the steel adapter.

The adapter I use was made/sold by USM back in the early 1980s.  It’s long out of production.  A friend of mine made a limited production run of adapters made from plastic.  These proved too expensive to sell for a reasonable price.  But have no fear, some clever folks have figured out how to make an adapter for parts of your toilet!  Yes, the doughnut ring can be used for something else besides a toilet.  The added benefit is that these rings are pretty cheap compared to the steel or plastic adapters.

People have spotted a lot of issues on my jeep over the years but no one spotted the dry air filter!  Don’t tell the jeep police!
