so i seafoamed my car a few times through the intake using deep creep, and also through the PCV port, let it savor for a few hours and cleaned the B out by revving. Well im now hearing even if you do it only through the intake, you still have to change oil, i just changed my oil like 4 days ago....is this true?

Yes, if you seafoam, you have to drain ur oil...

Or atl east that's what i keep hearing...

YoungKadafi

but how the hell does it see your oil? it goes directly from your IM into the combustion chamber, then burned out your exhaust.

i only ask because i used 1/2 can of deep creep into the Throttle body and PCV port on the IM, now its really hesitating, but sometimes has way more power than before, but mostly hesitating and being extremely raspy

i think thats only if u pour some in the crankcase...

you only need to change oil when you add seafoam to the oil, when you add it through the vaccum hose there is no need to change your oil

all the carbon blow by will go straight into your oil, and any excess sf will shear and thin your oil. change your oil regardless of how you seafoamed your car. increased insoluables and flashpoint of oil is not good and thats what happens after a seafoam. do an oil analysis right after doing a vacumm hose seafoam and you'l see a spike on the insoluables and the flashpoint will decrease (meaning there's undilluted 'fuel' in the oil).
