I have noticed our 2.4l dart will act up after getting a full tank of gas. ...
1) Never leave the car running when refueling, if its in a evap check phase it will see excess air pressure and start pulling a vacuum on the tank. You may be sucking in fuel ir just a lot of air.
2) You have a couple qts of water and alcohol phase separated on the bottom of the tank, and you are stirring it up; it settles out in about a couple minutes
3) You filled to past initial shutoff and flooded the evap purge canister.
I never top off or even try to fill the tank.
If I know I'm not going to be driving hard or WOT, Ill run near empty if i suspectt phase separated fuel, dump some drygas on there and run it near dry. You can add a little top oil in there, but Im not sure if you can cause sludge.
Oil and water are not good partners,
