I just got done cleaning my Air Filter (Stock Foam) and I know I need to oil it now.... how necessary is it to use "Air Filter Oil"??? I have been told you can use regular oil.. is this true? Thanks

You can't use regular oil. Use the correct filter oil or you'll have serious problems.

air filter oil is more of a sticky oil so dirt will stick to it motor oil is not you can get a can of air filter oil of about 6 bucks or so
