Doesn't matter how long you wait, you're never going to get it all out. There's always at least a quart left in the engine on and in internal surfaces. My wait is about 10 minutes.
My references were always to the point of keeping a car past the 200k or even 300k mile mark. Are you hurting your engine at your miles? Meh, maybe not, only thing that'll tell you that is a tear down which isn't really warranted. Carry on.
Glad you posted, that Deoxit is great stuff. I need to have a look in there myself one of these days. There was a TSB some time ago for later models addressing that very same problem, water egress.
Depends on how long you want to keep it. Like I said, buildup around rings takes time. If you did a tear down around 200k you'd see the problem. Plenty of videos around showing this because of extended OCI. 100k come to think of it is relatively young these days. Running great now doesn't really...
take it apart and give the circuit board a good cleaning with a tooth brush and alcohol.

ANY winter tire is better than an all-season. I used to buy Blizzaks but now am happy with and will settle for Coopers. Look for an aggressive tread with good siping. Don't overthink this.
This seems like a good place to start. I've had an issue with all 4 locks firing repeatedly on occasion since new. Dealer pegged it as a "can't replicate problem" even after I showed them a video and it happened on their lot in front of the service advisor when picking up the car. Anyway...
Yeah, I think that is pretty much a joke. It always amazed me how when I had my car in there for 30 minutes they always managed to check everything off on that list, including checking the trans fluid which involved dropping the bottom cover and checking it at the proper temperature of 122 degrees.
