This debate, which I characterize as the fire hose versus garden hose contest, has yet to provide facts to prove whether DOF lubricated IMS bearings last materially longer than similar bearings lubricated by splash oil alone. So far people have put forward several hypotheses that one approach is better than another. Without comparative bearing wear data or statistically valid samples of equivalent real world experiences, however, there is no objective way to settle the question as to which approach provides the longest bearing life. More oil volume might be better, but then again it may not. Only data that directly predicts longevity can show which supposition is correct.
