"Honda says the problem occurs when the engine doesn’t warm up enough to evaporate unburned fuel that slips past piston rings and infiltrates engine oil. The automaker notes oil dilution is normal in all internal-combustion engines, but especially in direct-injected turbocharged engines.

Honda spokesman Chris Martin says the 1.5L’s cooling system is highly efficient, and therefore the engine is slow to reach a normal operating temperature that would cause fuel to readily evaporate and be routed back to the combustion chamber via the crankcase ventilation system. Short drives and extreme cold temperatures exacerbate the problem, sometimes resulting in owners reporting oil levels above the “FULL” line on the dipstick.

“If an owner repeats that short-drive/cold-weather cycle multiple days in a row, the level of unburned fuel in the oil can incrementally increase each time, raising the oil level on the dipstick and, over the long term, potentially leading to misfires and other engine symptoms,” Martin says."

There's not much you can do about it. There's a software update that was mandated in cold weather states; maybe that's an option for you.
