I bought a paper air filter replacement the other day and when I took my air filter apart I found that I had an older oil bath type. Doh!

Does anyone know how efficient the oil bath type of air filter is? Is it a worthwhile job to replace with a newer dry air filter to get more air into the engine?

I cannot comment on the efficiency of an oil bath filter however if you have an old car that is original you may wish to keep it that way.
The correct thing to do with an oil bath filter is to take it apart, clean it thoroughly with paraffin (or similar) and reassemble it using new oil.

HI
The oil bath Air Cleaner is quite efficient. I would fit a "Dry" Macro filter for this Country, but retain the original for any "Original" Show.
There is No difference in Air consumption.
