Does Seafoam Actually Work? (with Proof) - YouTube

Hey guys, ChrisFix here and today we are going to check to see how well seafoam works in

a small engine like this lawnmower, before I test this out in my car engine, I want to

see if it works in a lawnmower engine.

It's easier to test, it's faster, and we can get a good idea of what to expect when we

do this test in a car engine.

In this test we will see if seafoam actually does what it says.

we will do this by looking into the engine before the seafoam, and then seeing how much

carbon buildup is in there.

And then we will run seafoam though the engine, go back in, and see if the engine cleaner

actually remove the carbon deposits.

So lets get some before footage and see what it looks like before we add the fuel cleaner.

So this is a four stroke honda engine, for a push mower.

Ok, this is a single piston engine.

I have the piston pushed all the way back so we can get a good look at this.

You can see the little groves for the two valves, one is an intake valve, one is an

exhaust valve.

This is a carbureted engine.

You can see right near the intake and exhaust valve the engine is pretty clean but right

above that, it is all dirty, there is some carbon buildup.

Lets see if the seafoam can clean up this carbon buildup.

Before we add

the seafaom, you

want to get the engine nice and warm.

So

we

are going

to start

it up, and

let

it run for a few minutes.
