Gear Oil Test

The one on the left is a full synth 80w90 and one on the right is Schaeffers 267 80w90. Both are filled with standard tap water on the bottom and like amount of gear oil on top of the water.

After 1 min of vigorous shaking in the same hand, I stopped and examined the results. Notice the air trapped in the full synth on the left and how the Schaeffers 267 has very little. It's impossible to remove all trapped air in any lubricant but with the proper blend of additives you can reduce the amount present. Air trapped creates more heat as it will not allow lubricant to get to the places where the air is trapped.

In this case, after just a few seconds you can see where they both are starting to separating from the water.

In the above picture, this was taken 15 secs after the initial shake up. As you can see the Schaeffers 267 has already separated most of the water from the oil. Notice the difference between the two foam lines.

As you can see in this both are attached to the same mechanical egg beater mechanism so both are being rotated at the same speed. The Schaeffers 267 on the left is climbing and the other is pushing away from the egg beaters.

Although this isn't the Schaeffers 267 gear oil, This gear oil contains the same moly properties as the 267 and as you can see, the moly has some interesting affects on the metel surface.
