The truck forum thread we had on SeaFoam recommended 50miles. I wouldn't put more than 200miles like someone mentioned... Basically just before your oil change, put some in and then be ready to change it very soon after (depending on your daily driving mileage)

 

hmmm this is nice to know some people were saying it eats the injector o rings. may have to try this to clean out my system

I usually do it 8 to 10 miles, but it says it can go longer in the oil without any issues. In my truck i usually go up to 100 miles before I get the oil changed.

 

e85 eats fuel pumps, o rings and injectors etc so whats the difference really. When running e85 in the car seafoam is kinda useless because it already cleans out the system pretty good.

 

Totally agree^.

Will have to try this stuff. Has mileage has been sucking lately

 

You wouldn't be disappointed

 

I used sea foam @ 40k miles and not only was it incredibly satisfying to see all the smoke but after the car felt smoother and fixed an exhaust leak. Maybe it was placebo but the engine noise seemed deeper. (Maybe due to the fixed leak?)

 

Wait, what? I love seafoam as much as the next guy, it definitely smooths the engine out, cleans out the carbon build up and what not. But fixing a exhaust leak? How'd it manage that?

 

no I think he means he discovered an exhaust leak and fixed it... hopefully haha. If you do have a leak you will know it because your garage will fill with white smoke

 

Well I put my hand near the test pipe about two weeks before the sea foam and noticed a little exhaust escaping at idle. After doing the sea foam I went to replace the gasket to fix the leak but, to my amazement, it fixed itself. No I'm not 100% sure it was the sea foam, but I'm thinking, what else could it be?
I theorized that maybe it plugged the small leak with all that crap it was spewing out.

 

^^^^ Love it when stuff fixes it self. Lol

 

Anybody here you Amsoil with seafoam, and ill effects? Has Amsoil said to avoid using this stuff?

 

Cause it has nothing to do with their oil thats why. They think being there oil is this and that the detergents wont help or some odd reason. I just love how companys don't want you to use a product like that but yet, there is no evidence of failures due to it. Seafoam is the **** when it comes to everything. Unless your car has 10000000000000 miles on it and never had an oil change its kinda useless to put in the oil. Being we ( or most of us) take care of our oil changes and what nots its kinda useless to put in the oil. But works really well for most of us who infact do use pump gas. Being I personally run both pump and e85 there isn't as much need for seafoam, but I use it religiously in all my other cars that do not run e85.
