If anyone is going to use this in their oil. Be cautious.

There has been a huge debate on BITOG(Bob is the oil guy) forums on this very subject for years.

Seafoam has a very similar chemical composition to carb cleaner.

It is best to be cautious when using it. My suggestion if you are going to use it,mix it with fresh oil,maybe one viscosity weight higher than normal(Seafoam will then out oil) and run it for 500 miles then drain it out with a filter change as well.

I don't see why not...however, I wrote this and feel safest recommending the exact procedure for the eigth gen because that's what I own. From what I've heard, ninth gen F150s have very similar components so I'd assume the procedure is similar as well.

It has been some time since I wrote the original article, but when I did I called the manufacturer of Seafoam and had a nice long conversation with him about what seafoam was and was not safe for. He swore up and down that seafoam will do no harm in your gas or oil tanks. I have put seafoam in the oil of my Honda civic and run it 3500 miles and had no problem. So I think it's safe, but I guess a matter of preference.

I don't know.There is a possibility that it took out an engine on another forum. Granted he put it in towards the end of his OCI and his oil was probably thinned out further than the 5w20 it started out as.

I would just rather be safe than sorry.


Here is a chemical breakdown of Seafoam vs Carb Cleaner

So I just finished up doing this and when I first reved the engine I didn't get any smoke whatsoever. I decided to take my truck for a spin on the road and see if I noticed any improvement. I was idling at a stop light to make a u-turn. The light went green and I floored it around the turn and kept accelerating. It might be a mind game, but I was really happy with the way my truck was running. I looked back in the rear view mirror and noticed a huge mushroom cloud of smoke back at the light. This stuff works great!
