I’ve been seeing some really good mileage reports from everyone which is great, but my 2018 Expy XLT Max only get about 17.8/gal highway doing about 82mph and 15-16 city using 87 octane. I see a bunch of you reporting 18-20 city and 20-22 highway. Are you guys running premium fuel or driving super conservatively? I’m not too much of a lead foot but I want to make sure I don’t have an issue with tuning or the adaptive transmission not running as efficiently as possible.
