is it necessary to change oil right after using? i was going to seafoam my car TOMORROW but i wasnt going to change my oil for about another 1000miles. can i wait that long? and if not, why not?

 

jus dont go more than 400 miles after u seafoam. i seafoamed my engine and it made a hell of a difference. its made to break down all of that gunk. after its all broken down u wouldnt wanna continue driving around with all the breakdown so then u get an oil change. honestly i would change after 100mi

 

seafoam is magical

 

how did you use this product(sea foam) again? I'd check the sea foam site, but just to be sure how you use it. is this safe for newer car? like my 2007 accord se...afraid would mess up the u2 sensor...

 

there is no need to use on a 2007 car. its safe for all cars, but you will only really notice it on high mileage, older cars. even more so, on cars that have used regular gas its entire lifespan, and typically gunky oil (non-sythetic cheap-o, ie quakerstate, pennzoil (regular), or off brands). like biackromeo said, its made to break down the gunk in the engine, and make things run smoother. cars that have lifter tick issues (like G1 acura legend, as well as some others) it makes those problems disappear.

a lot of people use seafoam just before changing over to synthetic or just as a tune-up every 5 or so years. yes, in some cases it can gum up the O2 sensors and require replacement or a thorough cleaning of them, but usually it is alright.

and 1000 miles is a bit long for leaving seafoam in the engine. I would wait to do it until the day before you do your oil change. do the 1/3 1/3 1/3 method of crankcase, gas tank, pcv valve (which car on) and then run the car 50-100 miles at peak performance. make sure to replace filter after wards, as well as pcv valve.

 

i was thinking of using it to clean my fuel system, but afraid that it might screw up the o2 sensor or fuel is too rich that might discoloration(reddish) of spark plug. thanks for the insight...IkeRay.
