oil film on a/c filter, what could be causing this?
I cleaned my filter on my a/c unit, and it had a oil film on it, have a roof a/c on my Itasca, 2006 motorhome. a/c works fine, any suggestions would be appreciated. Tom

I'm still wondering, doesn't seem like this oily deposit would be from cooking, however if I pull the a/c cover off and run the a/c while I'm on top would I be able to see the problem if I have a leak?
