The trip meter on my 2015 Honda accord is not accurate.
Bought 2015 Accord 3 months ago. 2 friends bought the same 4 cylinder model around
the same time. Their trip meters register 26 MPG in town and haven't been on the
highway yet. I drive in town and not on the highway and the trip meter registers 20-21
MPG. Had the car serviced twice and was told that there is nothing wrong even when they
could see the trip history. Zeroed out trip A&B before each fill up, no improvement. Help.
City driving is very tough on the engine. No driver is like another, and that would make a big difference and as such no two cars will give you same mpg even if they are brand new, and that is why even the manufacturer uses "Average". Now where you live you might have some hills, where your friends live there might not be any, that would be a huge factor for lowering your mpg. If you run into many stop and go lights/signals or live near a school area, where speeds are reduced and eventually you accelerate when you pass school area, you will get lower mpg. If you wait until you reach the red light/stop sign to hit the brakes whereas your friends coast the car from far when they see red light, that would make a difference too. Do this as a test. Zero both trips, and drive in the city where there is at least couple of miles long highway, not freeway with speed limit of at least 45 mph. See what your average mpg you get. And let us know, I would be very interested to know and might be able to better diagnose. Oh and check the tires pressure too, take it to Discount Tires they will check your tire pressure for free, no affiliation with them at all.
