ok i have tried to look this up but cant seem to find anything about it ..everyone mentions either one or the other but i want to know whats the best way to use sea foam through the throttle body or thru the brake boosters vacuum line???
or everything i read mentions to use 1/3 of the pint so how about 3 ounces each location in the same application

 

i just put the whole can in the tank at night so it can soak in with the gas, and call it a day

 

i was planning on putting a can in the tank to and some in the crank case since i was way over due for a oil change...but was wondering the best application , the throttle body or vacum line or even both at the same time

 

for the liquid stuff, it goes down the vac. hose, the spray stuff goes in the throttle body

 

Saw an official video from Sea Foam on youtube...they say 1/3 in the gas tank, 1/3 in the crankcase and 1/3 into either the throttle body or a vacuum line into the intake manifold.

I just Sea Foam'd my XJ a week or two ago...I used a whole can into the brake booster vacuum line.

 

^^ He is correct, I just did mine. You can split it 3 way like that but I personally only used in gas tank and in oil. I put a whole can in each, but they were also seperate times, Im not sure if you can put a full can in both at the same time but DEF. notice a difference after a few times....Use in all my cars btw
