I understand small changes are difficult to track especially since my gas mileage can easily change 5+ mpg from one tank to the next.
I will report any findings over the next several tanks.
If anyone else has any results from using this product or any other 0w-30 product (as I'm sure almost all 0w-30 oils will have a lower viscosity then their 5w-30 or 10w-30 counterparts) feel free to chime in.

I think that the 2% is just for the engine and will not translate to an overall FE increase of 2%. I think the biggest plus is less wear and tear during cold operations where most damage is done.
Might try a search. I though there was a thread on API Fuel conserving engine oil requirements and testing. I did a quick search but did not find it.
