I have a 73 185 with the small tanks, which is new to me, and have noticed that the fuel usage is much greater from the right tank than the left. It is confirmed by sticking the tanks.
The plane flys wing level. The other day I flew and at one point, fuel selector on both, the right tank indicated empty and the left was over half full. Sticked it shortly after landing and indeed that was the case. I had thought I had read about the tank vent tubes had to be positioned properly for equal fuel usage but in reading the service manual they only mention it as to reduce icing.
Learned the hard way if you top off the mains don't park it other than on the level and if you can't do that then select one tank or the other to prevent cross feeding to the downhill tank.
