  In this paper we investigate the general features of "Oscillatory Inflation".
In adiabatic approximation, we derive a general formula for the number of
e-foldings $\tilde{N}$ which reduces to the standard expression in case of the
slow role approximation and leads to the Damour-Mukhanov type expression for
the slowly varying adiabatic index. We apply our result to the logarithmic
potential and arrive at a simple and elegant formula for the number of
e-foldings. We evolve the field equations numerically and observe a remarkable
agreement with the analytical result.
