Amsoil PI - For real or manufacturer's hype?

[Craig in Canada]

How does Redline SI-1 flow through your throttle body, exactly?

Don't be a butt. Is everyone a wise guy.

 

[surfstar]

I was wondering the same thing, actually.

I just used the Redline SI-1 in the tank, i've only used Chevron Techron before. I already had the tank filled so I just poured it in with a full tank which supposedly isn't the best way to do it.

 

[Doc8404]

good point...did you run it through your booster line?
if not, how did it clean your TB inlets?

 

[ewetho]

Depends on the car does it not, If it is TBI then that make all kinds of sense, does it not???

 

[Doc8404]

no, not really. the throttle body inlets ?
they don't see fuel.

 

[coolman]

So it's clear. The car is tbi. The bottom bore/inlets were stained. You can see were its super spotless/shiny, where I assume gas mist/spray hit the bottom of the inlets. Wasn't like that before it was dirty and stained.. Better idea? So it has to be gas mist/spray coming in cntact with the in side woking of the inlets.As nothing else is being put through the throttle body.

 

[coolman]

If you can't grasp that? I can't explain any better

The TBI unit for my car, it explains that you need to clean the throttle blade opening because it becomes "gunked" up with gum and varnish.

In the case of units like this, it might make sense that the unit could be cleaned by the same fuel.

 

[coolman]

You said perfect, what I've been trying to say.

Never had Redline SI-1 do much of anything for my cars in the old days. Most anecdotal input I get outside of BITOG web and person to person is that Redline doesn't do much in the tank. Just my opinion. I was never high on the old Amsoil PI.

I bought some of the new PI from Pablo... Put it in my BMW at the cleaning dosage as reccomended. I have an emissions test coming up at the start of may (Ill use the tank through and only be on the first tank afterwards when I take it in). Its a dyno test, and Ill see how we do compared to the last test.

The car has no EGR, and just a breather tube instead of a PCV (its a 91 BMW 318i), as the stock setup. Runs great, excellent fuel economy, new cat, new O2 sensor, etc., but just squeaks by on NOx.

We shall see what happens, this to me will be the ultimate test...
