I recall that in early direct fuel injection (DI) engines there was a significant problem with fuel deposits on intake valves. There was discussion that this required very frequent oil changes to counter this. My question: Has this problem been solved? Is there still a problem of fuel deposits on the intake valves of direct injected engines? It seems that most cars I'm considering to buy all have the DI motors.
