Wifes RX300 Seafoam?

[toyotakid1996]

Longtime TS member, 1st time Lexus post. My wifes 02 RX300 has approx. 130,000 on it. I would like to clean the cylinders from carbon build up as well as change the plugs to some new NGK's. Truck runs good but when you start it cold it could be a little smoother. When we got it it had 112,000 on it and purchased it from a good Lexus dealer in AL that did a good service on it(skipped on a few things) but overall took it through the paces. We (my brother a Porche Audi tech) cleaned up what they missed on some more detailed items and have switched to a clean routine of Mobile 1 every 3k and premium fuel. So alot of Tundra guys love the Seafoam product introduced into the engine through the brake booster vac line. In my head this seams like a decent solution to clean out that carbon before I replace the plugs. But I will not add anything that might be questionable to this fairly technical and picky 3.0 6 cyl. Ideas Comments please. Thanks in advance for opinions.

Bump.... Well I now know why TS is called Tundra Solutions, because I have had this post in the Lexus forum for over a week or so. 63 people have looked at it and no response. Doesn't really matter or bother me, I got the info I needed elsewhere. But the point I'm making is that all these people looked at it and nobody said a word, nothing. I can post in 1st Gen Tundra and get 7 responses in an hour. I guess it kind of represents a Lexus owner, will look under the hood but will rarely do anything besides check the oil. If the car is lucky.

Old post for sure....Don't use Seafoam! I won't be bashful to say this.
Why haven't yu searched elswhere on TS regarding Seafoam???

Hope this helps. If your brother is truly a Tech...he should be in agreeance with me!!!!!!!!!!!!!
The only additive I would use to remove any carbon and clean the fuel system is Techron

Premium fuel is not really any advantage in this 1mz-FE engine.

Hope this only response will help yu.
