Congrats on the new Civic. My 07 EX is also tango red pearl, but I don't know that the color is going to get you any extra mpg. Did you get the 5-speed or the automatic? I was surprised that the numbers for each were almost identical - that used to never be the case. I have the auto and so far it's given me a myriad of different mpg readings. Keep us posted.

I don't really believe the color affects mpg although I guess one could debate if the higher temp underhood from a black car absorbing and white reflecting sun heat is enough to affect mpg. I know you can put your hand on a white car at noon in July and can't touch a black one but don't know if that's enough to affect mpg due to higher intake air temp.
I filled mine yesterday to reset the trip odometer and get a baseline. The dealer reset the trip when they filled it prior to delivery but I don't know just how they filled it. Based on mi/odo it got about 33.2 in mixed use but that was only on 4.5 gallons so not enough to be very accurate.
My usual system is to use the A odo on every fill and the B to accumulate a half dozen or so and then calculate an overall figure. I find that more accurate than the individual calculations.

Well more directly, what really happens is the A/C is (user) set to work and works harder in a darker car than in a lighter car. Whether it converts to hard data or not, it would need a side by side test and then the sample size would probably be too small.

Finally have enough miles on my manual 2007 Civic to get a pretty good idea of mileage. Ignoring the first tank from the dealer it has averaged about 43.6 mpg over 1110 miles, 650 hwy at 55 to 65 mph and 460 miles of short (15 mi round trips) mostly at slow speeds but few stop signs. Lowest tank was 42.7, highest 45.9.
I think the 45.9 was a direct result of watching the ScanGauge II. I'm still trying to find the "optimum" hwy speed, so far it looks to be quite low.

Don't need a ScanGauge. The best mileage is obtained in top gear at the slowest speed you can go, 40-45. Don't lug the engine! It's just not safe to go that slow on the highway.

Agree that 40-45 in 5'th looks best on level road and no head wind, otherwise not enough rpm. This is a surprise to me.
Any idea of the mileage difference between 55, 65 and 75? I'm getting a stupid urge to take a trip somewhere just to find out.

Be careful don't go too slow!! I would estimate 10% 55 to 65. 13% 65-75. Just guessing. It's the wind resistance.

I'll guarantee you if you slow it down you'll do MUCH better. I've already observed that. I also think the A/C is a really big factor. When I got the outrageous mileage in my new Civic it was on a much cooler day at leisurely speeds (nothing above 70).
As I've said before, I can't wait until we get some cooler weather to see what kind of difference running with no A/C makes. With the 100+ temps we've been having over the past week and a half, I've had to run the A/C on Max almost constantly.

Estimate the a/c at 2-3 mpg.

I would expect the A/C to have a much bigger effect in slow speed city driving. I've only used it once so far, mostly rolling hills and couldn't really tell much effect. What does make a big difference is to not use cruse control in hilly country.
I usually drive under the speed limits at night without cruse control in my area, due to the animals on the road and light traffic. This results in considerable mileage improvement, from around 45 mpg daytime to near 50 at night over the same 100 mile stretch.
