Hi. I'm new to Honda. My 3.5L Accord EX with 125k miles runs 2500 RPM's at 70 mph. RPM's normal at idle. Does that seem normal to all you 6 cylinder owners? I've always owned 6 cylinders who ran around 1900-2000 RPM's at 70mph, but they were all American models. Fuel economy is not very good and I travel mostly highway.
