My last two fillups were "On the Road" so I didn't have my trusty bottle of Wally World 2-Stroke to add on fillup.
There was a marked increase in 'Injection Noise' (clatter) on the trip home.

Added my WW 2-stroke when I got home last night.
Had to make a parts run awhile ago for a gasser Dakota project.
Noticed the noise decreased quite a bit on the return trip.

Wow, the soy-based bio-diesel fuel at only 2% tops the list for wear reduction. I could only imagine that higher blends would improve that further.
