Seafoam Treatment

[VehiGAZ]

I did it last year, but only in the oil. The engine was running pretty smoothly before, but even smoother afterward. I noticed the rough running spot around 4500 rpm went away afterward. I balked at putting it in the gas tank because I didn't want to drive around with smoke pouring out of the pipe.

I just got done running about 20 miles with it in my oil, then changed my oil.
I throw a can into the gas tank when almost empty & fill er' up with hi-test three or four times a year, never notice any smoke.

Huh - well that's interesting. I recall several people saying that it blows white smoke like crazy when you put it in the tank. I'll give it a try...

mine blew smoke like crazy when i dripped it in through the intake, gas tank and oil didnt give me any smoke

[VehiGAZ]

That's what it was! I think I tried sucking it into the intake, but the engine died the second I unplugged the PCV.

I'm going to give the 928 the Seafoam treatment as soon as it comes out of hibernation...

I've used it in the crankcase and in the gas tank. I didn't notice much of a difference. I am going to do another treatment with my next oil change.
