These 1.5 turbo engines seem to be notorious for getting fuel in the oil and increasing the level. The oil was above the high mark when we got our car. We just did an oil change too and I purposely filled it to just above the low mark, I'm hoping that starting low will account for the rise due to fuel over time.

The fact that you are compensating for the gasoline that is winding up in the oil (pan) is very interesting. According to Honda the gasoline will be burned off / evaporated when the oil gets hot enough. If you drove long enough to get the oil to that temperature (and probably for a certain length of time as well) then you will be back to the one quart low mark. One must consider why a certain oil level is recommended initially for a particular engine. You must have enough oil to lubricate all of the engine components that require oil lubrication. There may be a built-in reserve to account for any leaks, or for oil shifting in the oil pan (as when going around a curve at high speed, or the tilt of the car causing the oil to pool to one side of the pan - going up or down hill, etc.). I rely on the engineers that designed the engine to know how much oil is optimum. At one time the theory was that to much oil would cause foaming - a oil & air mix. Air does not lubricate anywhere near oil does. The only way to know for sure is to test how much is too much (oil), and at what amount is too little (oil). I hope you will get other responses to this dilemma.

I am only one of many so statistically may not be significant at all but my car‘s oil was filled to the top line when I picked it up last December. 8,000 km (nearly 5,000 miles) later..very low for me on account of covid..still at top line.. I have mixture of lots of short trips and occasional longer (1,000 km) longer trip. On account of this forum I have checked levels many times, minimal fuel smell, obviously no fuel dilution. Happy with the car, no issues at all.

Good to hear. Not a fan of turbocharged engines for longevity though. Time will tell if the Honda turbo will last at least 100,000 miles or more. Let's see how long those direct injectors last also. Anyone out there know the price of those injectors & the labor charge to replace them?

What makes you think Honda's turbos or injectors are any different than other manufacturers?

Depends on the supplier. DFI injectors are also subjected to higher heat levels - most likely shortening their lifespans. How much do you think the cost of 4 DFI injectors will cost with the labor charge? Something to consider when buying a turbocharged DFI engine.

That may work if the gasoline is in a vapor state. If it is still in it's liquid state (which it would be if the oil level has risen) the PCV will not vent it back into the intake.

How cheap can Honda be switching to that plastic orange dipstick? Bean-counters should stick to counting beans & not a couple of dollars that a metal dipstick would cost.
