I added seafoam to the crankcase a couple days ago and have just a simple question. How long am I supposed to keep the seafom in there? I don't want to keep it in there too long and have it eat away at my crank and bearings and such. I checked the can and it doesnt have much info as far as usage is concerned. So, if someone could help me out here I'd appreciate it.

you're screwed!!

don't keep it in very long!!! you should do this before an oil change

oh, your fine. usually people leave it in there for around 500 miles. just change the oil when this mileage come up.

500 Miles is fine, I have run it in other vehicles for about a 1000 miles with no problems

It's not like a motor flush that has extremely harsh chemicals and can dislodge chunks into your oil galleries. It is a gentle laxative for your oil and slowly cleans. I've known guys who put it in on a Saturday and change their oil the following weekend. No problems, no leaks... runs smooth.

Alright, cool. I'll just leave it in there for a couple hundred miles or so and change the oil. Thanks for the info.

anywhere between 250 - 500 miles is what most people here do. Uhm, I think you're also supposed to change your oil after 1000 miles after that, make sure you get all the gunk out.
