What "GAS TREATMENT" additive should I use to clean injectors?

I was planning on buying some SEAFOAM...but where Im living right now, It cant be delivered....

I was going to use it since I read so many good reviews on the seafoam treatment...

I just want to clean the injectors from the inside...

I know there are places where they clean it professionally...with sup[ersonic vibrations etc...but...in my case its all about location...no near shop that does that..

Whats a GOOD brand of fuel injector cleaner that you add to your gas tank?

1993 Nissan Quest. with 93K miles

I just cleaned intake manifold and plenum from the inside took it off...replaced hoses coolant, fuel and vacuum...all new gaskets...etc...new fuel filter...oil and fuel filter replaced...fuel injector o-rings...cleaned by hand the outside of it...cleaned fuel rail...new IAC valve gaskets...EGR gaskets...etc...

Now...Im concern my injectors are a bit clogged...I tested the injectors for resistance and solenoid movement and are OK...

Is STP a good brand? What about GUNK? 3M?

Never used "fuel injector cleaner" before...

any suggestions? thanks!

    Chevron Techron is the best. CRC "Guaranteed to Pass" is second best.
