I've had this issue for a while as well, probably 2-3k miles, sitting at 8k now. MPG decreased substantially when it started. The other day I noticed that the oil smells extremely strong of fuel, in addition to the level being higher than it was after the last oil change. So it seems that either the oil/fuel dilution is really, really high similar to the problem Honda 1.5Ls had, or the injectors are leaking into the top of the engine after shutdown. Has anyone else smelled their oil to see if it also smells of gas? And is the level higher?
I requested the Blackstone oil analysis kit which will arrive tomorrow, so hopefully in a couple of weeks we will know if it's a severe dilution issue. 2% is the max acceptable tolerance for fuel dilution but I dread it's going to be +10%.
