[Mgs] when to change oil again

[oliver]

hi, all.

last spring we bought a car which had been sitting in a garage for 30 years.

replaced all the fluids, hoses, hydraulics, and related items, had gas tank 
refurbed, etc.

we just got the car running and driving a couple of weeks ago.

any recommendations on when we should change the oil again?  do i need to do 
that soon or can i wait until i've put a few thousand miles on it?

thanks!
