The best oil to apply, as OF said, is the 2T oil. It will never be mentioned in any manual "
that we should apply 20W40 on the filter after cleaning it."

Second, by applying we are not CLOGGING the filter. Thought the air flow is restricted but it is negligible if proper quantity of oil is applied. Infact by doing this we are helping the filter in doing its job more efficiently.

You can keep it for long but its good if you change it periodically. Like for P220 I get a new filter after 15-18K kms. After all it does not costs me a fortune and is easy to install too.

One quick note - you have specified in the article to clean the sensor.How we do that?

Didnt get you? We are not cleaning the sensor. We are just cleaning the filter so that sensor does not cause the warning icon to blink.

I am asking this because I have bought a new foam-type air filter today and will be changing tomorrow myself. Shall I apply oil, because I am taking it to Ladakh and the bike will eventually be gasping for air. There is a compromise in applying the oil, that is why the question.

If you check the filter once you get your bike back from service station, you will find oil applied on it. They do not give bikes with dry filters

Petrol is very hard on such thing. It will shorten the foam's life
