FlyNBHappy....you seem to offer the notion that there may be some variability with Bakers AA. Running "several batches"with no rust ???

I've run the stuff consistently for almost 30yrs and haven't seen a problem, so use it with abandon! It's an old, tried-N-true product. It's good stuff.

FWIW...I've run BeNol as well in some other engines and find it to run well, albeit nowhere near as clean as Bakers. For the price, BeNol ought to be sensational, but it seems no better than Bakers, and Bakers costs less, PLUS it runs cleaner in my experience.

Go figure.
