How to seafoam ?!
Am going to seafoam my LS400 with one can of seafoam.
I don't know if what am going to do is either right or wrong!!
Can you guys help with the steps of seafoaming.
i have searched around the forum and found that we have to put
- 1/3 in fuel tank
- 1/3 in engine
- 1/3 in brake booster hose.
Turn car off for around 15 minutes and then start the car and enjoy with the smoke show.
oh and also must replace engine oil/filter after the seafoam.
Is that correct or i missed something?

I get low MPG on highways; I get maximum like 17-20 MPG
Already tried most of solutions from what I have searched/founded in the forum and I just want to clean the car engine/fuel system/spark plugs/injectors/manifold from inside from any carbon build ups, so I may get better boost drive + better MPG , who knows it may improve MPG !
Recently I had even replaced the old engine of my ride which has (270000 miles) on it with low mileage (7000 miles) engine; it was imported from Japan… but still no improvement in MPG.
Car runs great + with no CEL + already tried almost everything.
People recommending trying sea foam to improve car performance and MPG. Is that wrong!? I just want to try this? Nothing to lose!

Did not try to change to coolant temp sensor yet. BTW I saw the ECT thread which was posted in the forum.
Have checked O2 sensor reading using OBD2 device on idle during closed loop and open loop. Since am not getting any CEL, am assuming that O2 sensors are performing fine. I can post O2 sensor graphs readings if you can help with diagnosing the O2 sensor readings!!!
Since (O2 + ECT) sensors cost some cash am just trying to start using the cheapest methods first to improve the MPG. O2 and ECT are in my pending list.

I always fill tank with 95 octane gas.

if a few sensors are going to break the bank maybe replacing the motor before actually trying to find a problem with the old one wasnt the best and most cost effective idea ?

02 sensors are supposed to be replaced at 100,000 miles...it doesnt matter if u have a check engine light on or not
