I've never driven a vehicle with Seafoam added to the oil. I usually pour it in and let it sit and idle up until it gets up to operating temp for a while then drain it.
Either way I would add a bottle of stop leak to the oil when you change it next. Seafoam and other solvents are ******* engine seals and gaskets.
Eh I'm against additives and cleaners all together. Like I said I pulled my valve cover off and had absolutely zero sludge at 125k. No additives necessary.
