LphillipsWelcome to the forum! Lot's of great owners with tremendous experience!
Gas mileage is more dependent on how you drive. When I bought the H3 back in Nov. 2022, my mileage driving home (250 miles) was only 14 mpg. This month I am averaging over 18 mpg and that is a real mix of town and highway driving. I also use a good quality fuel system cleaner in every other tank of gas. Hope this helps you. Happy Trails!

Welcome. Maintain tire pressure at 38 PSI and start slowly as getting a heavy H3 to get moving uses a bunch of energy. Use top tier type fuel and enjoy!
