Pretty much it cleans out your engine and helps make up for the problems created from ethanol blended fuels. Over at the maxima forum guys are extremely critical and it actually appears to be generally accepted.
I didnt post a new thread because it's not %100 for mpg gains, but it sure can't hurt performance aka mpg.

I did a quick read on the LS1 forums - 51 pages - wow!
Quick check on BobIsTheOilGuy:
Pennzoil TC-W3 Full Syn - WM - Bob Is The Oil Guy
I am not an additive evangelist or regular, but use them from time to time. Lucas UCL or Chevron Techron. Never store brand. But maybe only 3 or 4 times a year.
If I can find this Pennzoil synthetic TC-W 3 2 stroke marine oil locally, and find some sort of bottle laying around to give me accurate dosage, I will be part of your test fleet. I have no UG or SG yet, but I have OEM avg fuel econ, plus my calcs at every fill up.
My MPG is seeming to be steadier now - cold weather coming though. But, I will add data FWIW to your new thread if you set one up.
