Some XPS leaked in transit

I recently changed oil and switched to XPS.  I found that when I used Aeroshell I routinely couldn't add a full 3 Liters, which would overfill the oil tank.  I routinely used the 100 to 200 ml (of the 3rd liter) as make up oil.

When I added the XPS I had to use the entire 3 liters to fill the oil tank to the middle of the dipstick.  I thought it was odd that the seals on two of the plastic bottles were broken.

At the Utah (Hurricane) Rotax fly in I learned that several of the Rotax dealers have experienced XPS deliveries where the bottles have leaked.

Another issue I have found is that the plastic bottles don't have a sight gauge with a calibration.  Previously, it was easy to keep track of added oil.  Now it is purely an estimate.
