Anygood?

is it worth it to buy for a 3 year old car?

 

if you search there are some posts about seafoam. but i use it about every 2 years or so. it helps to keep everything clean inside. just remember if you use it in the oil only drive it a little bit then change your oil

 

Yeh it works, there is no doubt about it... just don't F up doing it!

 

Thins the **** out of your oil, make sure to change it right away.
