Anyone having fuel dilution issues?

Just read through this entire thread and it seems that the underlying common theme is "short trips". HOW short? And is it only with the Direct Injection vehicles?

I have never noticed increasing oil levels (a symptom of dilution), but who is to say that the engine uses just a bit of oil and dilution is keeping the level good, leading me to believe I have no problem?

Regarding "short trips", my wife (the RAV driver in the family) does about 7 miles of suburban driving to get to work. Hers is an older RAV ('02) with port injection only. A couple times a month, she might go to our son's house (1/2 hour drive) or her sister's house (50-minute drive). My commute (in an '18 Sienna with port and direct injection) is about 10 miles, which includes about 4 miles of freeway driving. My job has me driving to locations to service equipment several times a week. Those trips range from about 3 miles to about an hour away. My van is our go-to weekend vehicle, so it sees more trips of the longer variety. Does either of these scenarios qualify for the "short trip"?
