I used seafoam in my car worked great and helped my gas mileage out! i was told to do as follows.


To seafoam your car:

1) use 33% on gas tank with 9-10 gallons of fuel. Cleans fuel injectors, fuel lines, removes moisture from fuel lines. Put it in gas tank at the gas station, then fill it with 9 gallons of fuel, so it can mix well. Just read the bottle for the normal mix ratio.

2) another 33% goes to your crankcase. so open your oil cap and pour it in. *WARNING: It thins out your oil. DRIVE FOR ABOUT 10 MILES, THEN CHANGE YOUR OIL. KABISH??

3) Rest 33% goes to the intake manifold. It cleans intake valves, cylinder, top of the piston, exhaust valves, etc. To do this, you have to use any vacuum line that goes to the intake manifold. In my altima the brake booster line worked perfect.


reps are appreciated!
