Some of u guys are getting some good numbers. In my 07 is350 I'm getting average on tank around 18-18.9 mostly city driving in Chicago and stop and go traffic on Highway. On the way home I'm on Highway no traffic for about 5-10 min. I'm happy. This is also in summer ac on all the time. I'm sure in winter it will drop. This is good enough for me.

Yes, you are correct. I did not say "low", i say "better" rolling resistant than the crap OEM summer tires. I chose the DWS because it offers great wet traction, balanced performance on the dry, better rolling resistant than OEM, great tread life, low noise, and comfortable.
cool, I have the DWS out back also but im running a taller tire, 245/45 instead of the stock 255/40. They are light tires considering what others weigh but the aggressive tread pattern I would say doesn't help mpgs at all. awesome tire nonetheless.

about 150 miles in one weeks time with 89 and 150 miles with 93. same road, same time of day so pretty much the same amount of traffic.
That pic is from today. 90% hwy/10% city. 15 mile drive, very little to no traffic. It was actually at 29.7mpg and went down to 29.5 once I parked in my garage.

My speculations as follow:
1. "E" does help assuming your force on the gas pedal is not harder than before. This mode makes the acceleration slower and good for traffic.
2. Auto vs +/- mode. This is too general and can lead to inconsistent results. For example, I can turn in auto mode, drive the **** out of it and drive normal on sport mode hence sport mode would have better fuel mileage. I can do the reverse to achieve the same thing. Also, in both modes, the transmission is still automatic. The comparison should be 1500 RPM vs. 2000 RPM vs. 2500 RPM vs. 3500 RPM vs. 4500 RPM shift point instead. I bet 1000 RPM shift point would give the best mileage due to being a turtle lol.
3. AC vs no AC. No AC will give 1.5-3 better MPG. I have personally tested this.
4. open vs closed ventilation. I would say minimal difference in MPG.
I have tested the following and achieve better MPG assuming no change in driving habit, driving on the same car on similar route.
1. F Sport intake for better engine breathing so more efficient engine equal better MPG. You confirmed this as well.
2. Lighter wheel weight such as the TSW Nurburgring (19-20 pounds each vs. 28-29pounds OEM wheel weight). Total of 36 pounds of reduced unsprung mass will require less rotational force from the engine to move the car and hence better MPG.
3. All season tires with better rolling resistant such as Continental ExtremeContact DWS. Don't go bigger and wider wheel/tires set up which will give worse MPG. Less resistant equal less force required to keep the car momentum. However, handling is not as good as summer tire.
4. Mobil 1 advanced fuel economy full synthetic oil. Yep, I gained better MPG using this oil than any other ones.
5. Driving habit. The MORE COASTING you can do with LESS GAS pedal application and SMOOTHER BRAKE, the HIGHER MPG. This can yield a significant MPG difference.
6. RPM shift point, the lower the RPM, the better fuel economy. I have tested 3500 RPM - full rev vs. smooth 1500-2500 RPM shift point on my IS250 on the 50% city, 50% freeway, I get 16 MPG vs. 24.5 MPG.
7. Lower your car gives better MPG. This lead to better aerodynamics especially when you drive a lot on highway, the car will have less wind resistant so the car can coast in high speed smoother without more gas pedal application and hence better MPG.
8. Less weight, better MPG. Driving with all 5 passengers vs. you alone will yield a difference in MPG.
Your finding about the oil change with last 5k miles giving better MPG is very interesting.

my 350 is running on 19 inch staggered so maybe that's why the most i've gotten from 80/20 hwy/city is 24 MPG. Also have a f-sport intake to help out.

im going to say once you get into stop and go traffic, your MPG will be shot
for my IS350, i drive 99% highway and i can get up to 26-27 mpg with an extremely light foot
but ONE trip with some traffic lights and that number quickly goes down
