2010 Hyundai Elantra with Beta 2.0 4 cylinder engine and 2200 miles . Since new the car was driven by the book (below 4K RPM's , below 60 MPH , using Tier 1 gas , etc.) for break in up to 1500 miles . The EPA estimates are 24 MPG for city and 35 MPG for highway for this Elantra. So far , I get no where near this MPG's on the highway (currently around 28 MPG) and in normal city driving I get around 23 MPG . I will add I drive it smooth and more often than not stay within the "Economy On' dashboard light (shows you are driving to conserve gas) . The engine is very smooth , the car drives great and no problems to report - except concern for low gas mileage . My questions are : Will the gas mileage improve ? Anything I can do differently ?
