GS300dude Posted November 1, 2009 Share Posted November 1, 2009 Should I try SEAFOAM on my 99 Lexus GS300 with 135xxx miles.?? I have never used it, and I dont have any problems with the car, BUT was just wondering if I could make it better. Thanks Quote Link to comment Share on other sites More sharing options...
NicLX470 Posted November 2, 2009 Share Posted November 2, 2009 Wow I had to google it to see what the heck that stuff is. Seems kinda old school. I'm sure OTC products like "gumout" and other fuel and oil treatments are just as good...but without the toxic smoke. The video that shows the exhaust that is emitted for a while doesn't seem very healthy for the catalytic system or any part of the car or environment.

djspawn00 Posted November 2, 2009 Share Posted November 2, 2009 i've used seafoam on several vehicles, don't expect a mechanic or miracle in a bottle, but other than that it does what it says... unless i've just been lucky. Quote Link to comment Share on other sites More sharing options...

I wouldn't say use it often, just every once in a while. If you haven't used SeaFoam or something like before then yes, a lot of crap does come out of your exhaust, but if you maintain it for the most part you won't really see a thing.
