The 8th Gen Civic tends to over-read (optimistic), but I have seen posts on here about the 9th Gen (e.g. Kremmen), saying that the 9th Gen fractionally under-reads. If that is the case, 92.1 mpg might turn out to be 95mpg. I know that seems daft, but a lot of 9th Gen 1.6 dtec owners are saying they can thrash around in their new rides, and still get 60-odd mpg overall, which is the real test. Please post again when you fill up, calculating at the tank, rather than the on-board computer. Thanks.
