I use Stanadyne lubricity formula only, I can tell when its not in there the mileage takes a big hit.

 

[dpuckett]

Here are the rest of the results. What gets me is that some of the aditives actually REDUCED lubricity, i. e. made a bigger wear scar. MMO was statistically insignificant, but made it a little worse. Lucas mad eit quite a bit worse. The WalMart 2-stroke oil scored higher than I expected, and at a much lower ratio (200:1) than most of us run (I run about an ounce per gallon, or 128:1).
