What do you guys think about using Sea Foam?

My 1998 Tacoma recently hit 180000 miles. My friend recommended me using sea foam. What do you guys think about it?

 

Highly recommend it,buddy of mine used it on his high mileage chevy truck that sounded like it had a rod knock after using sea foam it quiet it then he sold it and bought a Tacoma!Joking aside If heard nothing good about it.Im also thinking of using it on my rig.

 

Ehh. Decent at best. I'm not a huge fan of it.

 

Used properly it works well.

That's assuming you have a problem that needs fixing.

Boroscope cameras that attach to your phone are cheap. (like $15). Look in your cylinders as well as examining your plugs. If you have excess carbon deposits on valves/piston top, Seafoam will help.

If you don't, you don't need it.
