that depends from oil composition,
for example API for oils with (API) gravity in the range 15 to 35 gives a coefficient of expansion of about 0.0004 per degree F

for a more accurate estimate you can characterize the oil (i.e. define pseudocomponents) and then use a EOS for calculating the derivatives of volume vs. temperature and pressure, see
