Are you comparing new fluid to used or side by side new in the bottle?

I also wouldn't expect them to smell the same new since the formulations are different though. Like tires, not all treads and compounds are the same though they all meet the standards to be certified.
All I can say for certain is that MTL nor MT90 smelled strongly like an axle gear oil. They did not smell like an ATF though either.
The Royal purple maxgear did smell more like a gear oil than the MT series fluids did too. At this point I wouldn't recommend it. Their regular series of fluids will be fine.
