Not sure what screen "total fuel efficiency" is.
If your scan gauge is properly adjusted, then your scan gauge mpg and hand calculated mpg will be within 10% of each other.

Professional OBD-II Scan Tool is what I'm using.

I was only measuring Highway MPG
Not trying to cheat but that was the only way I could tweak the efficiency. I just started Hypermiling . I have a 2001 insight on the way. Which couldn't be soon enough with the camry down.
My V6 Escape suprised me today on my 180m commute it got 27.4mpg calculated at the pump. It has new Cooper AT3s "big tires" I had been getting 22mpg "tire pressure?" after the new tires. I was getting 26mpg on low test with the old tires. I added half a tank of Shell V-Power NiTRO+ Premium Gasoline and pumped up the tires to 44# from 30#. Wow what a difference the Shell made. If it continues I'll write a thread about the Shell V-Power .
