Handyhoward, I sort of agree with you in that each of us must make use of what we truly know as facts. I know in detail the conflicts that changes in greases can have and you know, you do don't you, that I cannot apply that information to lubricating oils.
If that is not true and you have not actually researched conflicts among oils, I suggest that you should not try to contradict what I have put up as something to consider when changing oil brands and specs.
This is not really a challenge to you but just a concern that I have if I try to switch around among oil brands and characteristics. Stated oil characteristics never take into account the result of changes from another oil, unless they specifically state that they do so. That is my specific point of view. I have no doubt that some oils are better than others. My concern is that going to a new oil that has not been tested for conflicts with previous oils is a good way to get into trouble, even if the new oil is far better for the engine once it is the only oil in that engine.
With the greases that I am familiar with, the new grease was far better than the previous grease, but unless every drop of the previous grease was removed mechanically, the new grease caused all kinds of real world problems because of the residue in the device. Who needs that kind of problem with an engine? This does not in any way conflict with my prior post but gives additional support to what I said. Unless a specific combination of oils has been tested, do not mix them at all. You do so at your own peril.
