I know that Redline's SI-1 contains a UCL, unlike Regane and Techron. Some people laud SI-1 on that fact alone. Obviously keeping the upper area of the motor lubed is a good thing, but why bother with SI-1 over anything else if the UCL and its associated properties will be gone quickly?
Does one need to use UCL with each tank to maintain those benefits? One kind of "one-time" benefits does a UCL offer?
Would DI engines enjoy any benefits from a UCL?
