About how many uses come from this can?

Each filter has a certain amount of ounces of oil that is required so a number of uses you will get from an 8 ounce can differ depending on the filter you are using it on.

Do we oil only the "dirty side" of the K&N Filter or do we also oil the "clean side"?

FROM K&N 4. OILING For best results, use K&N Air Filter Oil - Apply K&N Air Filter Oil liberally to the dirty side of the filter only. This will allow for a visual reference of complete coverage. A. If using a K&N squeeze bottle, squeeze bead of oil along the crown of each pleat using the lip on the squeeze bottle tip as a guide. Utilize graduated view strip on bottle to dispense proper amount of oil. B. If using a K&N aerosol spray, spray an even amount of oil along the crown of each pleat. - Wait 20 minutes for the oil to be absorbed into the filter media. Inspect the clean side of the filter for any areas that are lighter in color. Touch up these areas in the media by applying oil to the dirty side of the filter. Continue oiling procedure until there is an even red color over the entire surface of the clean and dirty side of filter.

Can this be used on "DryFlow" filters?

If your dry flow filter is washable/cleanable , then yes you can use the oil spray.
