I just wanted to get some input, my father in law suggested I use it so I wanted to see what you guys thought?

2009 F150 XLT
4X4

 

I use it in my Harley and my small engines,haven't used it in my truck or auto but wouldn't hesitate to if I thought I needed it!

 

for a new generation F150? why?

 

I've used seafoam to clean the intake manifold and run thru the gas tank.

Let the seafoam get sucked in thru a vacuum line into the intake. The engine will prolly putter so dont let it suck too much to fast. Slow and steady. About a third of the can. Shut the engine off.

Let the truck sit for about 30 mins let the seafoam really break up the crap stuck in the engine. Pour the rest of the can in the gas tank. Then start her up after 30 mins. Longer for better results.

depending on how much carbon buildup there was. the exhausted will smoke white. Take the truck for a spin and burn off all the white smoke. Enjoy!

 

That is good marketing, but not true. Naphtha, the main ingredient in products like Seafoam cannot completely burn in the combustion chamber, causing white smoke. Pure carbon doesn't burn at temperature engines operate at.

For a truck that new, unless you are using a poor quality fuel, a cleaner is not needed. Top tier gasolines usually provide enough additives to avoid problems. If you do want to run a cleaner, look into PEA based products like Techron and Gumout Regane. Polyether amine is a proven way to clean the system, without the negative effects of solvents.

The only time I've ever used Seafoam was to clean out the engine in a car that had been sitting around for a while by adding it to the fuel and oil. This car had around 150K on it, and had been sitting for about a year. A new vehicle should not have buildup to the point that you'd need to put any sort of solvent or cleaner in it.
