I have a 2008 is250, just came up on 60k I know my plugs are due but before doing that I want to run seafoam through the intake (vacuume line). Has anyone used seafoam? I've used it before in previous cars and it works real great in cleaning carbon, I have yet to experience the carbon build up problem with these cars (my check engine light hasn't come on but I have felt wired idling once or twice) do you think I should use seafoam?

 

Yup heres a hand ful of threads that can be found with the search function

Yes you should use it. Many have used it as early as 15k because of the Carbon build of the models before 2011. And yes what RDIS250 said its all over the search.

 

Yeah search is your friend.. I use seafoam with EVERY oil change.. i like to put a 1/4 in with the fresh oil.. 1/4 in the vacuum lines and the rest in the gas tank with a full tank of gas.. You will instantly see (mpg) and feel (vroom vroom) results

OP I have the same car as you - 08 is250 awd
