A two-level implicit difference scheme using three spatial grid points of Crandall form of O(k2 + kh2 + h4) is obtained for solving the one-dimensional quasilinear parabolic partial differential equation, uxx = f(x, t, u, ut, ux) with Dirichlet boundary conditions. The method, when applied to a linear convection-diffusion problem, is shown to be unconditionally stable. The numerical results show that the proposed method produces accurate and oscillation-free solutions.
