Miles to empty dropping fast
My miles to empty is dropping at a fast rate and
my dash says maintenance other
If you notice a progressive reduction in gas mileage, whether you have any warning lights or not, the first thing to look at is the engine air filter. If clogged, it blocks air passage and the engine gobbles up gas. If the filter is fine, you likely will have a CEL and the possible causes are myriad, from fuel problems to electrical, or even mechanical. Have this diagnosed by a mechanic.
