Well my normal exit ramp on the freeway is almost done. I decided to try a couple commutes back on the freeway for a few miles of the commute at least. I was very pleasantly surprised in that I made the same mileage as if I had taken the slower roads.
To work 61.9 mpg, ave mph 40 max around 65
back home 81.7 mpg, ave mph 37 max around 67
This beats 70 mpg for the day. I guess that is my target for now.
Tank is at 69.8 mpg with ave speed of 37 mph.
This is a lot less work and a bit quicker for nearly the same mileage. I had not commuted on the freeway for several months. I have done a few things to the car since then.
My gaslog is certainly leveling off after a long steady rise. There is no economic justification for more effort at this point. OOPS that sounds complacent
