Is there any benefit on using Seafoam on a brand new Prius?

Ive used Seafoam on used cars before and I know they do make a difference on older cars. But for new ones, do they actually have any real benefit? Maybe something like preventing gunk from building up?

What does Seafoam exactly do? I googled it and from what I saw it apparently supposed to clean your engine?
its only used to clean up gunk. if anything you can probably use it after 1000 miles after you break in the engine just to clean up any gunk there caused by the break-in period.
So it just cleans up the dirty engine. Sounds like its only good on higher mileage engine. That explains all the smoke I see in the Seafoam videos on youtube.
Thanks for all the info. I guess I'll just stick to using it on higher mileage vehicles. I just enjoy watching the smoke show that you get when you use it. Hahahahaha.
I've found that a clean engine comes from:
1. I use only top grade 100% synthetic oil & change oil & filter every 8,000 to 10,000 miles.
2. every 5,000 miles I put one bottle of Chevron fuel injection cleaner in an almost empty gas tank, fill the tank with 89 or higher octane gas and drive until the tank is almost empty again. (Do NOT refill tank until almost empty or it will dilute the cleaner.)

This cleaner seems to be the best in my experience. It really does make a difference. Toyota dealers also have a good cleaner that runs the same way.
Maybe something like preventing gunk from building up?
No, no and NO.

SeaFoam is mostly snake oil.
It was originally designed as a marine fuel stabilizer.
It is a decent stabilizer and a light duty fuel system cleaner.

ALL of those other claims and suggested uses are just so much BS.
