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?
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.
with no oil change required after the break-in and oil chnages at 10Kmiles, i would hazard a guess that it would be a complete waste fo money. maybe in five or six years
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 have used Seafoam Many many times. It works Great on Carbureted Vehicles, Our IQ's are fuel injected.
Fuel Injection does not really need anything until you have many many more miles.
I would wait till at least 10K then, a fuel stabilizer, that lubes the fuel pump & top end.

This is the best that I have tried.
I have no affiliation to this company, it just is a great product
