Milage vs. Mileage
“Mileage” is the main dictionary spelling for distance in miles, fuel efficiency, and related figurative uses. “Milage” is also documented by major dictionaries as an alternative spelling, so it is not accurate to call it universally nonexistent; “mileage” remains the safer conventional choice for edited prose.
Prefer “mileage” in general edited English. “Milage” is documented as an alternative spelling, but using the dominant form avoids needless reader uncertainty.
