For water, use the steam tables.
For oil, I assume you mean the change in SG from its value at 60F or standard temperature. The GPSA Engineering data book has a generalized chart that I typically use. It's likely published also in a lot of other reference books. There won't be much change in SG from going from 60F to 100F, not more than 1% or 2% for an oil.
The GPSA curve shows the SG as a function of temperature and SG at 60F. What I've done is developed the formula for the slope of those lines (they are linear over a reasonable temperature range) and then set up my own equation to estimate the new SG given the temperature and the SG at 60F.
