Wish I had a Scangauge years ago...

The scangauge is a great tool! Its showing me some interesting things besides the obvious best speeds to drive at for higher FE.

-Driving on roads that have 3mm standing water really eats into your FE! I often see 6mpg drop that can last for miles? Time to pick a better road when its raining heavy. What can I say, Louisiana roads are terrible...

-When your roof rack is literally whistling in the breeze its likely costing you FE.. Yep I removed the roof rack and it looks like it was good for 1.5mpg at speed. Nice!

-My engine is not getting warmed up near fast enough especially in the morning. Looks like 190F is where it eventually controls at if you drive long enough. Now in the morning all it ever gets too is 186F. I really can see a difference in FE when its running under 190F. I think what?s happening here is the radiator is over cooling the water keeping a good portion of the engine running too cool. I?ve got a thermostatic fan clutch so its pulling air at all times. One morning I ran the A/C for a short time to help heat the water then shut it off and sure enough the steady state mileage numbers jumped up to the range where there supposed to be when fully heated.
I?m really thinking about an electric fan conversion? Next thing I?m going to try is block off the bumper air intakes and see what that does?

Last fill up was 25.3mpg, not to shabby for a EPA combined 18mpg truck!
