z-max,anyone ever try it??

Shelby put it through serious tests and found it to be top notch with no residue after the fact.

I have used it in all my vehicles for the last 5 years and wouldn't be without it. I noticed a difference in the smoothness of the engine, and gained a little MPG....lots less friction.

We just put it in a friends slant 6 Volare wagon.....when you started it, you heard the usual dry bearing noises (not bad, just normal for old slants, but it makes you worry a bit).....after we put it in, there was a gradual improvement in the quietness of the engine, especially on start-up, and now, it's really smooth and quiet no matter how long it sits....as a matter of fact, I had to lower the idle speed.

That is NOT "snake oil"..........THAT, is scientifical factimication. :read2:

Good stuff. :blob:
