Microlighters

Lukewarm water and Sunlight Liquid. Swish around a few times and rinse with clean water.
I have never oiled any of my filters and I can't see the reason why either

If you don't oil the filter you loose a LARGE amount of its filtering ability, the result ? More dust into the engine resulting in shorter engine life. The oil captures all the finest dust particles.

These filters are designed to be oiled so oil them !

K & N advised me on Bikes filters not to clean with petrol. Apparently damages the fibres effecting airflow.

Advised to only use their expensive cleaning agent. .or if I can't find that Sunlight soap and water is just as good. Found myself not looking too hard for cleaner. But must oil after clean filter has dried.

My previous 582 with more than 800 hours under the belt doesn't think so

The oil captures all the finest dust particles

And blocks the filter quicker. Looks like a catch 22 to me.

So would you rather have the dust in the engine than on the filter ?

However long your 582 lasts, remember it would have lasted longer with oil on the filter :D If it blocks it shows that it is doing its job.

In the bike racing world this discussion went on for a while, till someone showed how much dust gets through an un oiled filter, that was the end of the story now they all oil (The ones who know what they are doing anyway !)

Washing it with petrol expands the fibres, causing less air to get to the engine.....

Where is a good place to get hold of filter oil? Available from the average autospares shop?

Yep, and then I have to do mine.......ie. execute a forced landing
Lest we go round in circles, I'm happy with what works for me. Thanks for the info regarding the bikes.

I have been using teepol for years, we used the same procedure in my previous industrial position in various installations.

Rotax uses K&N oil spray but for the past few years I have been using "King Dragon" filter oil which is sold nationwide by Jamex the Dutch sourced street racers suppliers. They also make a very nice range of air filters in competition to K&N and worth a look if you require a replacement. The King dragon is yellow and is very easy to view its coverage after spraying. I would imagine its performance is similar to K&N but is much more freely available in Deben as we have many Street racers which means more suppliers...

Always use oil..

I see Autosport sell all brands of oils and cleaning kits, Jamex, King dragon, BMC and K&N. so shouldnt be a problem just the price..

Be interesting to see what prices you come up with and maybe post them here...

eish Zulu1

Well if that happens you did NOT do your (preflight) job at all :D

But like you say, it works for you......

I have been buying the K&N oil from bike shops.

After much research I have been advised that rinsing in 2-stroke mixed fuel is the way to go, drop filter in a small can to let the dust/ hair etc fall off then rinse in another can and replace.
The 2-stroke residue is oil enough
K&N spray oil, its hard to ensure right dosage so most of the time you are putting on too much resulting in more time on the ground:(
This info was from the birdman with the most hours in Africa.
Backed up by the professor!
If it has worked for his engines for the last 20yrs it will work for mine
Tried and tested

In with Reza on this one... use two stoke mixture. Cleaned filters twice in 40 hours operation and the filters are definitely picking up the dust :D

I prefer warm water and sunlight, and always spray K&N oil on them afterwards

Agreed, cleaning it with petrol is a big no no for reasons given.

Collected K&N spray oil from Aviation Engines (R79), must admit, I did not make to much effort in finding it at local autospares shops, try the bike shops

As it has been said before, the petrol causes the fibers to swell in the filter material, causing less airflow, a richer mixture and less power. This is according to Rotax, Jabiru and K&N (And many top bike racers/tuners)

On my Rotax 618 the difference between a clean filter, in the past cleaned with petrol, and a new clean filter was a bit more than 200 rpm at top end ! I have now washed the new filter once with water and "sunlight liquid" and the top rpm stayed where it was with the new filter, even washing the old filter in soap and water did not restore the rpm.

I recently bought a large spray can of K&N filter oil from my local Midas store, this is the can that is about double the normal size, for R 59.99, will last me a LONG time. Due to the red colour of the oil it is very easy to get the filter evenly covered with it as you can see where more is needed, it only takes a minute to spray a filter.

Fly safe,
Rudi
