Okay i just put seafoam through my intake manifold 2 days ago!(not in the oil), well anyways do i still have too change the oil in it at the moment or not? (i didnt put it in the gas tank either?) Just the "IM" so LMK ASAP

 

you only have to change the oil if you put it in the crankcase from what i understand

 

unless you think your rings are shot and some might have seeped in the oil, no need to worry about that. How old is the oil anyways?

 

i changed it a day before i put seafom thriugh my IM!
