Here's my 3+ years Kelisa Auto mileage:
RM30 - 250km (about 16km/L or 12 cent/km)

Driving condition, 50% highway, 50% urban.
Stock Kelisa with K&N drop-in air filter

Yes, it is re-useable. Performance just a slight boost, but the FC does improve. Used to be about RM30 - 220+km, now can get RM30 - 250km. By the way, I also don't rev my engine a lot or floor the pedal for pickup... just steady acceleration.

Reuseable basically means for as long as your car is still kicking (literally). The filter needs to re-oil after every approx. 70000km. Go K&N website to find out more

I do usually drive around 3k rpm or more along highways... but at a steady speed (approx. 80-90km/h). So does it affect my FC? I'm not too sure, haven't drive on highway slower than 80km/h.

Well, I think its worth to give it a try... It does give me a little extra mileage. It works for me and my driving style.

Kangyoon20 in this forum got sell, I bought from him.

A bottle of oil to re-oil the air filter cost about RM65 and only needed after every 70000km and this one bottle can use about 7-8 times.
