I just purchased a 2003 Legacy Outback with the H6.3.0 engine and VDC. It has 74,500 milkes. This is my first Subaru and I really like it. To my chagrin, I learned that it requires premium fuel and NO ethanol.
What has been other owner's experiences? Why is the ethanol bad if the octane rating is acceptable?
I would appreciate any comments. Thanks.
