Oil is not typically a major resource, but in cold winters in gas pipeline-constrained areas, i.e., New York and New England, there is quite a bit of oil generation. Even in high load summer days when gas is available but the load is much higher than the winter you'll see a bunch of oil units turn on. Oil-fired and dual-fuel units in those RTOs (NYISO and ISO-NE) also make up a pretty large amount of the total installed capacity.
