I recently changed the grease in my bike pedals from a plain white lithium grease to Valvoline GM/Import. I flushed the bearings and bushing out and have greased them 2x since. The Valvoline grease seems to be darkening much more quickly and becomes thinner than the previous grease did. I don't feel any play in the bearings, and they don't normally see any wet weather.
Is this residual grease reacting with new, or just the nature of the new grease ?
