When does fuel dilution happen?

Diesels running post-injection event(s) for DPF regen are common fuel dilution victims. I hear Ford recently implemented a dedicated injector in the exhaust stream to address the issue.
Interesting.
Want to cut down on air pollution? Stop eating cows and drinking milk. It's something that people will have to do on their own. Right now big business and politicians instead of helping are feeding the fires.
I'd much rather drink milk than the kool-aid it appears you've been swilling.
Next up on the Kalifornia agenda is to have people eating nothing but insects like the UN proposed...

This is a joke, right?

Guess what happens to the grass the cows don't eat? It decomposes... a natural process that primarily creates CO2 and Methane!!
cool-aid is right... the cows are killing us all!

When I did the last oil change for our 2.3 EB Explorer I noticed gas smell in the oil. It smelled stronger from the open fill cap than in the drain pan
. This was a 7,000 mile run in roughly 2 Summer months, mainly high speed highway. I did an UOA and while the oil, Mobil 1 5W-30, was still in grade it was borderline 20 weight. I changed it to Motorcraft 5W-30 and will change it out at approximately 5,000 miles or in January. I'll do another UOA to see how the fuel dilution affected the 30 weight oil grade in more "normal" everyday driving conditions in the cooler/cold temps. The 7,000 mile summer run showed low wear metals. We'll see how this run fairs out.

I know... As soon as this Journey is paid for I might dump it for something that will be around a lot longer and the last of the non TGDI / GDI's and definitely without a CVT (Continuously Vomiting Transmission)

Immediately after starting the engine. You have EGR or it's equivalent, PCV, piston rings, etc., all contributors.

This is no doubt true. But some DI/TGDI engines may also use mixture as a way of preventing LSPI and reacting to regular spark knock. With the extremely low highway revs common in modern cars, they may be in those conditions more than we'd expect. Richened mixture may solve the LSPI/spark knock problems but can also make fuel dilution worse. This could also be a reason some posters here (including me) have found higher-octane fuel reduces fuel dilution.
Maybe the introduction of GF6 oils will allow OEMs to be less-aggressive in these countermeasures, at least when GF5s disappear. Maybe they'll even have reflashes available for older model years.
