A metered oil supply is supposedly more efficient and therefore economical than rough and ready premix, but my own ETZ oil pump runs much richer than the recommended premix ratio of 50:1. This seems to be the common experience; I have not heard of anyone who gets a leaner ratio, as one would expect.
Can anybody explain this?
Have any ETZ owners kept a record of their long term 2T usage?
