Anyone have any serious issues with a 2016 Hyundai Santa Fe 2.4L AWD Premium. I find I am actually obtaining better highway gas consumption than manufacturer stated. Secret - Use PetroCan regular gasoline and make sure you use ECO. Dealer put Esso gas in the vehicle and I got very poor consumption numbers, 11 L per 100. When I filled the tank several times with PetroCan regular and driving the same trips, using Cruise and ECO averaged 7.5 L per 100 Km. Then tried a tank of ESSO regular and sure enough, consumption increased. Any suggestions for good tires? I have Kuhmo and there is a lot of road noise. Is there a good Bridgestone All Season solution out there??
