So I've given the Infiniti to my nephew to drive. He's a good kid and needed a car. His driving style definitely falls under the severe category: - Only city driving. - 3 mile round trips to school. - Stop-and-go driving when school lets out. - Small town so grocery store, fast food, friends' houses are only a few miles away. - Morning idle time is 5 minutes to clear up windows and get interior toasty. He fills up premium gas (mfg recommended) and routinely checks fluids & tire pressure. Current fluids are Castrol 5w40 syn oil and MaxLife ATF. I've asked him to hand calculate his MPG and he gets around 14. Considering this driving style is pretty hard on a 16 yr old car in the winter -- fluids don't fully warm up, fuel dilution, multiple starts a day -- is 14 MPG fair with winter blend gas? The EPA city estimate is 17.
