I wasted a lot of money on synthetic until I figured this out....but then when working on a fleet of L-39s they used typical wheel bearing grease from the auto supply store, go figure.
I simply use generic automotive wheel bearing grease for disc brake wheels, red in color (e.g Pennzoil grease). It's always worked well for me. For the tailwheel bushing I use Lubriplate Aero white grease. Seems to work perfect for me. My tailwheel bearings are sealed so whatever grease they have in them is good for the life of those bearings (deluxe composite tailwheel from Flyboy Accessories).
Just so you get the entire range of options to consider, you can always get Alan at Antisplat to change your bearings to the sealed kind. Then you can throw away all that bearing grease you purchased and not worry about it any more

"Mobilgrease 28 is designed for the lubrication of plain and rolling bearings at low to high speeds, and splines, screws, worm gears, and other mechanisms where high friction reduction, low wear, and low lubricant friction losses are required. The recommended operating temperature range is -54ºC to 177ºC (-65ºF to 350ºF) with appropriate relubrication intervals. "
