Just shy of 90 mpg US on a 100+ mile round trip tonight... as per pen and paper, same station, same pump.
Scanguage certainly helped - but actually showed a higher number for the tank - despite my now seemingly dialed in adjustment. Could it be the Scanguage is a bit wonky once it hits 100mpg? Not sure, but will investigate further. Some segments were showing between 110 and 120 mpg as a current trip average. No, I haven't set the fillup adjustment up so the mpg show as imperial! I normally use LHK, but MPG was more enticing tonight.
Temp tonight was 7c to 8c. Intake temp as low as 13c, and not more than 19 or 20c. Elevation changes minimal... the lowest about 20 feet, the highest 135 feet...
All cruise control, various speeds - trying things out, using Scanguage as reference...
I have several mods planned for the smart, which I hope will let me get close to 75-80 mpg US day in and day out in regular driving, and closer to 100 mpg US on straight hwy trips.

Yesterday I changed the oil in the Civic to 0w-20 M1 and the tranny oil to 5w-20 M1. Used a PureOne oil filter. Checked the air filter. Installed a new WAI hose. Rotated the tires and set the pressure to 50 psi. Checked the brake drag with a good look at the other suspension bits and pieces. Basically went thru the car from bumper to bumper.
Decided to make a test loop run in the car. Best I could muster was 60 mpg by the SG with no wind and 50F temp. The very best Ive done on this loop is 70 mpg in the middle of summer. With a 27 mph average. Yesterdays speed average was 35 mph.
I spent most of last night thinking about grill blocks for the Civic. And do them with class and taste. I came up with several idea's. None of which are easy at all but will produce good looking parts.
But even with all that work I don't see more than possibly 2 mpg,, if that.
I'm amazed at CO ZX2's results. No I'm stunned! Absolutely stunned! Knowing what I know of the ZX2. CO has to be one hell of a driver! Wayne better watch out!!!! LOLOLOLOL

Be carefull with temperature gauge observations when there is no water being circulated.
Depending on the placement of the sensor will vary its truthfullness.
The water temp is an average at best , if you slow down or stop the flow completely you could be showing a normal temp but in reality be boiling watwer is certain parts of the engine.
I have seen many times cylinder head warpage or partial seizures when there has been air in the cooling system.
This doesnt show up as higher temps on the gauge - but they are there.
So the point is , dont believe the temp gauge 100% - ever.
