I have a 92 F150 5.0 with E4OD , ran a can through my intake and put one each in my gas tanks . Was reading the can and said you could add to your oil , Anybody have in thoughts on that? Oil should lubricate and adding Sea Foam may cause the oil to break down.Engine has 93k on it .

 

I'm sure SeaFoam has some usefullness, however it isn't really going to fix anything.

Bad plugs, wires, sensors, etc......
I wouldn't put it in my oil.

 

You add it right before you change the oil. Put it in and run the engine for a few then shut off and change oil. It cleans all the crud and sludge out. It is not to be added to the oil and left in like an additive you leave in.

 

Here is the technical breakdown for you guys that keep stuffing this product in your engine.
