Superior Court Judge Dudley W. Gray's ruling released Wednesday found that most owners of that type of car achieve fuel economy close to federal EPA estimates.
A court commissioner had previously ruled in favor of Civic owner Heather Peters, awarding her $9,867.
Peters opted out of a class-action settlement giving some 200,000 owners between $100 and $200 each, plus a rebate if they buy a new Honda, electing instead to sue the automaker on her own.
