I really like your car and what you've done with it

I've been poked

Hi drainoil!

I only keep a steady speed on highway if I can't get the tailgater to pass me,and there are more vehicles behind it,then I will do the speed limit.

If I'm alone,I will pulse and glide between the speed limit (55MPH) and perhaps 40 MPH.

If terrain allows for longer glides,I will EO(ff)C.

So I don't know my average speed but yes it is less than the PSL.

In town the engine is off more than it is on and I can get the MPG display to stay high sixties to mid seventies while matching traffic flow.

About the RPMs, I really don't know how much it would help to have taller gearing but I still say what I said before. You do not get the impression of a high revving engine while driving the Mirage.

Could be the 3 cylinders? I have never driven a Metro or other 3 banger car before to compare, but something about the harmonics that make it sound like lower RPMs than what it actually is.
