there's always that possibility, but typically no.... most people however do this right before a spark plug change.

I usually buy 2 bottles...

Bottle 1
1/3 in break booster vacuum line
1/3 in a vacuum line from the front of the engine (can't remember where it's been a while lol)
1/3 in the oil crankcase

Bottle 2
Gas tank!
