How much does a Renault cost to run?
About $1,297 a year in fuel, at 12,000 miles and $3.20 a gallon. Over five years that is $6,485, before a single service.
Why does the Renault average look low?
Because it spans 3 model years, back to 1984. Cars built before the mid-2000s were markedly thirstier, and Renault has 10 ratings from that whole stretch — the recent ones are pulled down by the old.
