Attached is a table of my gas purchases and DIC info since day 1. I see two entries where the DIC MPH was 45.
Date Odometer Miles Pump Gallons MPG DIC Miles DIC MPG DIC Gal. DIC MPH
09/14/2008 6,953 330 15.519 21.3 330.0 21.4 15.4 45.0
09/06/2009 17,118 435 17.290 25.2 435.7 24.1 18.1 45.0
Must of had a headwind on 9/14/2008.
I accelerate slow - RPM max is usually ~2200 or below before it shifts. I also try to drive close to the shift points for lowest RPM.
Shift Points MPH
4-5 32 (Will stay in gear at 33, not 32. All others are ok.)
I think those are actually torque converter lock-up speeds.
Sometimes that puts me above the speed limit - e.g., 44 in a 40 zone - and sometimes below the speed limit - e.g., 45 in a 50 zone. I do drive 35 in the 35 zone as I'm already getting the drivers behind me upset. But, if the traffic would do 45 in the 35 zone, I would to. Seems about 5 over is what most people do in town.
I drive 65 on the IL toll roads and 68 on the Indiana Turnpike. Faster then the trucks and slower then all the cars in Indiana.
I use the speed control all the time - even on my short 7 mile drive to/from work. I notice many times when the car won't shift or won't lock up the torque converter until I turn on the speed control. I think that's odd and often wonder if the computer may be doing something else. I see this all the time with my desk top computer and Windows Vista too.
My wife asks why I didn't drive like this 20 years ago. I tell her gas wasn't $3 20 years ago.
Anyway, probably more information then you wanted. And, none of it answers your question.
