Yeah, I'd throw some new cheap oil in there, and crank it for 10-15 seconds several times. May as well throw some fogging spray down the intakes and spark plugs holes before you do that also. Put the old plugs back in with a smear of antiseize too. Then you'll have a pickled engine better than most, and shouldn't have any rude surprises when you get back to it. Wouldn't be a bad idea to stuff some rags in any exposed orifices either.
