Well, the noise came back next day, so the fluid was not such miracle as I initially thought.quote:

My first impression in using it in corolla: nothing!. But wait, where is the engine noise I had on acceleration. Gone! Note sure what happened but seems like I had bad pinging and GTA FE fixed that. Looking forward to checking MPG.

This is a way to interpret: the legitimate sources of GTA FA dried up.quote:

I don't really know how to interpret the last couple of days of this thread. I have nothing negative to contribute about the GTA product as supplied by APDinc. I cannot comment on other suppliers. I think that HMW PIB is a useful fuel additive with respect to emissions and mileage (at least when under load). I think that any interpretation of this thread that suggests that the GTA product was faulty or that HMW PIB is a scam would be an interpretation in error.
You convinced me. I found the TX approval letter for Viscon in diesel fuel (below) that shows decreased PM but slightly increased HC, just like your Montana study.quote:

It's why I added the second post. http://deq.mt.gov/Energy/bioenergy/biofuels.asp This test shows that the Torco has significantly less prticulate polution compared to other oils in a 2 stroke and attributes this to the PIB so it's it may be getting a better burn and is acting as more than a detergent here. Then again the HC emisions are a bit higher so that would contradict this though that difference is in the margin of error for the test conditions which were stated as being poor for absolute repeatability. Probably not the right form cosidering the overall visc. of the mix but it may be worth a look.
I'm not sure it's an issue. If you check the Montana study that goodvibes referenced, the Torco oil has only traces of P that is harmful for cats. It has some Ca (probably from detergents) but I'm not sure if Ca is harmful for Ca (doubt it). No data for S though but S is a known reversable cat inhibitor.quote:

As for Torco smokeless 2-stroke oil, also keep in mind that it is not ashless. Use of such oils as fuel adds introduces a significant mineral stream to the catalytic converter.
