Oil coming out the tail pipes?
Are you absolutely sure it's oil? I can't possibly imagine oil getting into the exhaust and not just burning. You'd be leaving a blue smoke screen behind you.
My guess is that you're running pig rich, and the condensation in the exhaust is causing black liquid goo to drip. My IROC did it so bad it stained the floor where it would sputter out of my tail pipes.

If the vehicle did sit for extended periods of time it is possible there may be a lot of varnish on the rings/cyl bores and not making a good seal and oil shooting out if the previous owner did not do regular oil changes. Could also be the valve stems seals may be dried up and broken and oil is leaking past the valve stems. Before I'd spend a lot of money I would buy a can of Sea Foam engine treatment and follow the instructions and see if that does anything for you. If that doesn't work, then replace the valve stem seals and see where you're at after that....
Valve seals will cause this as well - mostly at startup. Once oil pressure builds, and the seals get nice and wet, they will seal better, and the motor won't smoke.
Do you notice this mostly on cold start-up?
