seafoam

For me I just put it in the crankcase and drove her for about 30 mins and when I went to change out the oil it was beautiful with no sludge.
I have read about other S40 owners putting it through the vacuum line and it does a good clean but make sure to be in a WELL ventilated space as there will be lots of smoke coming out the exhaust.
