Does this sound like fuel dilution?

2000 Ford Explorer with OHV V6, 184K miles

Ran Seafoam in crankcase for a short time just before last oil change, and also through vacuum line 3 weeks ago. All of EGR system is new except actuation solenoid. PCV functional.

Have been running M1 5W-30, roughly 3500 miles on it. Looks very clean but not viscous. Oil level is a bit high whether checked "warm"/cooled-down or cold, not completely sure but possibly slightly higher than when I filled it. It smells strong too.

No noticeable loss in fuel economy. Idles smoothly since Seafoam & EGR replacement.

I plan on changing the oil once I hit 185K and getting a UOA. Is it possible that a significant amount of Seafoam got into the oil from the vacuum line or maybe even didn't get drained out from the last oil change?

The seafoam will make you engine run smoother for a short period because it is an upper cylinder lubricant. this won't last long. Seafoam IMHO is snake oil. I've experimented with it when manually cleaning carbon from parts, its a poor cleaner. And if it is a poor carbon cleaner when manually scrubbing I find it hard to believe spraying into your intake will do anything. As for gasoline contaminating your oil (and increasing your crankcase volume) I wouldn't say that's the case. Gasoline in your oil will be evaporated through the PCV and wouldn't contribute to an increase in volume. Do a UOA for peace of mind, it won't hurt.

Seafoam is weak stuff.Berryman B12 is harsh and rugged.

I'd imagine any Seafoam in the crankcase would have evaporated by now?
