You can put an oiler at the tool itself:

Just remember to fill it every 3 months or so.

This is the sort I use, I have a male quick connect coupler on one end
and a female on the other. My air tools all have short whip hoses, all
the instructions say not to directly connect fittings right to the
tool. This way I can use the same hose for air tools as for spray
painting with no oil contamination. If I need a little more
flexibility, I can just add oil directly to the tool whip and skip
attaching the oiler. You have to be careful with what oilers you do
buy, some of the sort that HF carries leak, badly. Other brands that
look identical, don't.
