I sell it and have about 15 customers and not one has switched back. One consideration is the time and filter costs. Semi SAE50 trans. oil does not contain friction modifiers in my brand and the conversion some times does not get the notice diffs and engine oil do with regard to performance and fuel mileage with the exception of cold performance.
