Does it work on oiled filters?

No, the K&N 99-0624 Synthetic Air Filter Cleaner Spray is for K&N dry air filters only.

Can i use this to clean a aem dry flow air filter ?

I have 2 AEM 21-203DK Dryflow Air Filters that I use this on.If you watch the K&N video bit.ly/1ODiK2v , it should answer all of your concerns.As for drying time, I rotate my filters on a 6 month basis (as I only put 5000 miles on my car annually).The video suggests that you should let your filter thoroughly dry (or at least slightly damp) before reinstalling. So if you clean it late at night and let it sit in a well ventilated area till morning, that should also suffice.

Is k&n 99-0624 synthetic air filter cleaner to be used on ru-3102hbk universal air filter?

Yes...use it on any oil-free synthetic filter. I use the AEM Dry-Flow filter, but it is made by K&N. Do not use citric degreaser products as those will clean but will remove the color in the filter. You can also use AEM 1-1000 Dry-Flow filter cleaner.

New to Amazon and bought this air filter cleaner and it all leaked out or was busted and the boxes wet what do I do
