In my previous post regarding the city mileage of my 2004 Passat with GDE tune I had managed to collect 93 data points on a consistent route to work providing me a baseline average MPG of 36.8 via the car multifunction display (http://forums.tdiclub.com/showthread.php?t=423256). In my last oil change (5W-40 CJ synthetic like the previous oil changes) I decided to add about 250 Ml of LiquiMoly MoS2(http://www.liqui-moly.us/liquimoly/produktdb.nsf/id/us_2009.html?OpenDocument&land=US). I then proceeded to collect the same type of data for the same route between 10/12/15 and 12/18/15 yielding 37 data points with the results shown here:

I wanted to see if it was even possible to measure any gain in fuel economy using this methodology. Well the results somewhat surprised me:
* 100% city average 2004 Passat wagon without LM MoS2 = 36.8 MPG
* 100% city average 2004 Passat wagon with LM MoS2 = 37.9 MPG
* Gain = 3%
One could attribute the difference to the margin of error if the gain was less or equal to around 1% but at this point I cannot rule out an impact of the Molybdenum disulfide additive as a friction modifier improving FE. I cannot comment on highway mileage as I do not have a consistent way of collecting the data to make apples to apples comparison.
Anybody else with MoS2 experiences and FE?
