Nope, water has more heat capacity than oil. About twice as much per unit volume, depending on the type of oil. The hydrocarbons that store and release more heat than water do so because of phase change (melting/freezing). Think of things like beeswax, candle wax, and the like. The latent heat of melting is 100 times as large as the specific heat capacity. This means the heat required to melt a certain mass of wax is the same as it would take to raise the the temperature 100 degrees! Not a trivial amount of storage capacity by any measure.
