You’re right, it should not even be a concern.I walk to work.
I mostly use the car after work and on weekends. I try to not just make short trips, I prefer the temperature meter to be up to temp the way it is supposed to be. Sometimes I do make some short trips but overall I try to at least drive long enough for the operating temperature to get to where it should be.
I rarely check the oil to be honest. My mechanic has never told me he smells gas in the oil, but I can ask him to check that from now on during oil changes and I would be able to examine that with him too (local garages FTW). I tend to change it between 4 - 5 K, regardless of what the MM says.
Can't use a block heater where I am. Apartment life and all.
That's the thing though, this should not even be a concern. You're supposed to be able to just drive the car however you do without giving it a second thought.
Some argue it’s a characteristic of DI engines. Well then that doesn’t sound like a good design. Maybe DI eeks out an extra mile or two per gallon of gasoline. But you might end up dumping out several quarts of oil earlier than you should. That wastes oil, money, & your time getting extra oil changes. I haven’t run any numbers, but it’s probably cheaper to full up with gas a few extra times than to pay for those extra oil changes. It’s certainly less time consuming than driving to a dealer & waiting for an oil change.
