Default New Best MPG for me!!

I Just wanted to see what MPG I could get just changing gears at 1600 RPM and going 50 MPH / 1450 RPM. the night before I topped off my tank and reset the trip meter and DIC. I started early in the morning (6:00 am) heading to Columbia hoping to miss most of the morning traffic.....I should have left earlier!! I know I made some people mad ... sorry folks if you were behind me. At about the halfway mark the DIC was showing 45.9 MPG. I had driven 66.9 miles. On the way home the fuel gauge was only down 2 bars and the trip mileage was showing 124 miles. So i find the closest gas station to see how much fuel I used. At the station i was showing 125.1 miles and I put only 2.811 gallons in the tank. I was/am pretty impressed!! The DIC dropped to 45.4 and I calculated the average MPG to be 44.5 MPG see below picture for the halfway point... still going 50mph. Of course when I went on the interstate I sped up to 60 MPH and stayed in the slow lane for about 14 miles.

I can get 42 mpg if I drive straight highway on a long trip.
At speeds between 55 and 65 no AC. Let's be realistic. You drive with the flow of traffic to be safe on the highway. 40 mpg is a good number but not realistic with the driving patterns we use.

Hey cool! If you try the experiment again, maybe try 60MPH, see how much it drops. Might be still over 40MPG.

I got 40-41MPG on a long trip that I used to do regularly (6.5hours), 70-75MPH on the highway (about 60%) and 50-60MPH on state roads (40%), little or no A/C, with my 1.8L/5sp.

For a small car the Sonic really is a pretty comfortable highway cruiser...

I normally drive 86 miles round-trip each day to work. I may do that experiment one day this week and post results.
You're right about our cars being great for trips. I really like the way it handles especially going around Sharp curves.

I need to try these tips in the few posts here to see what MPG I can get.

Have a 2017 with 1.8L and Auto with only about 2,500 miles on it so far. The best I have seen is abut 36MPG going 45 to 55 MPH for about 77 miles. For general around town stop/go 50%, some semi rural 25% and freeway 25% driving I was seeing about 32MPG.

The car is snuggly tucked away under a cover in the garage for winter with a battery tender on it. The "Red Rampage" is our version of a Summer Cruiser. .

I haven't had this much fun driving a car since the '91 Firebird.

As I have mentioned before, I get 50 mpg at 50 mph according to the DIC.
I took a multi hour run at 75 and got 37.

Alright, finally finished the 60 MPH test. Still shifting at 1600 RPM only this time I drove 2 days to work and back (172 miles). The DIC displayed 41.8 MPG. I calculated the MPG after adding 4.155 gallons to the tank (stopping at the first click on the pump as I always do). It came out to be 41.4 MPG. Normally, I get 37 MPG on this trip, however, I was changing gears between 2000-2200 RPM. Another 4 MPG is a considerable difference. I guess shifting earlier in the RPM's really help. See picture below for the display prior to the fill-up.

12 bars total. 12x60=720 miles.

Uh, no. Nobody is getting anywhere near 720 miles out of a full tank with these cars.

The most I've gotten so far is 520 on a tank. Gas light was on for a while. I was praying it wouldn't run out of gas!! Thank God it didn't.
