How can you judge the milage on a couple of tank fill ups? I left my last dealership ( a Honda store in December of 06), and can tell you that it is too early to judge milage issues.Normally, one has to have at least 7500 miles to consider poor milage claims; nonetheless, I would suggest that the vehicle be taken into the dealership for a check with the scan tool and driven to see if its out of normal operating specifcation. Keep the receipt showing what was checked and if anything was done. Also, purchase a auto expense book, keeping track of milage; date of fill up, miles at fill, number of gallons, etc. Also keep track of service records.The idea here is to actually see if milage is improving as the engine/vehicle gets more miles on it. Engines are tight when new and normally, the rings and valves have to "wear into" a pattern to seat fully for the longest life and most power and milage. Have some patience, by keeping track of it and having records you can ask Honda to look into the matter if the situation does not improve over time. This also may protect your legal rights and gives you other possible options should not get satisfaction.Hope this helps, a car nut
