would it be wise to seafoam a motor with 200k+ miles on it? my friend wants me to seafoam his crx lol...also my ls motor only has 2k miles on the block and not even 1k miles on the head...should i seafoam it too? or should i wait for it to build up some more miles?

As far as i know about that it wont hurt anything i have an empty can downstairs if you want me to type out what it says on it

I used it on my mazda with 40,000 miles and could feel a big difference, and used it on my gf zx2 with like 70,000 samething, noticable difference...it says it is safe to use so go ahead put some in the PCV vac tube with the car running and add some with an oil change and add some to the gas tank...well thats what i did and no complaints should be good to clean up a high mileage motor...have peopl had problems with this in the past?

i tried the two can method. i had one can go to the gas tank, half in the crankcase, and half in the vac lines. then you let it set and then turn it on. then white smoke all over your neighborhood! it was sweet. lol. i'm about to do it for my tacoma and that has 160k on it. so do it!

im sure that 200k motor could use it. i noticed a difference when i first did it on my 90K B18C1. know i little bit with each oil change

dont put too much in though, i read on here somewhere this kid hydro locked his, so be carefull. and at 200k miles, your ***** probably held up with carbon, so maybe just a little.
