2013 Sonic RS . . .

Automatic. Left the Avg MPG alone since I bought it the week before New Years . . . just under 6K miles . . . the Avg is now up to 32.8 on the DIC. I love this little car !

 

[SeanK]

Driven 25,000 Miles

1.4 Turbo 6spd man. bought in oct 2012.....lowest MPG 37.7 MPG...Highest 43.5

Driven By me Hubby gets closer to 33mpg

That is using the MPG function in the computer....I do drive more highway...but this includes driving into and within Boston......

I go by the DIC for these numbers, which tends to be about 2mpg optimistic. Close enough for me, now that I know. 1.4L 6MT

If I beat on the car every time I drive it, all city I get about 28mpg.

Now, I beat on it a vast majority still but use the idle-down fuel cutoff and average 33-35mpg. I could knock on 40's door if I wanted, but it's not worth it to me.

Highway, 70MPH I avg about 41mpg. I slip streamed a large trailer once and got about 48mpg. good times.

Im 62k miles. 1.4 6spd manual .I was averaging 39mpg. Almost all highway and DFW traffic. Changed my tires to Bridgestone turanzas and my milage has suffered ever since. The last month I have been averaging around 36mpg. All numbers are from the dic.

1.4 automatic sonic. Stock the best I've seen is 31. Driving 65 90% highway

 

[AK-Brando]

Only had my Sonic a couple of weeks, but I am pleased with my mileage.

My last tank hand calculated to 36.98 mpg and here is what OnStar says:

Our local Quik-Trip sells E091 (no ethanol, 91 octane). Since switching, I'm getting 35-36mpg 30%-70% HWY. I was getting 31-33 on 10% ethanol gas... it costs more so I've not done a real cost analysis...

Have about 620 miles on my '14 Sonic Hatchback LT Turbo Automatic so far 33MPG City / 36MPG Highway. I also have a DDMWorks CAI without the heat shield installed and I use 87 Octane.

 

[joe truck driver]

finally updated my fuelly again(137- 58,000 miles) and am missing many(30,000 miles and mostly summer) receipts... can't find them anywhere....

at this point we haven't had any real hot days in a row so I still can't match apples to apples on the trans, but I don't see a lot of difference in mileage. so I'm figuring they got it right.

have done 60 mpg(64.2 on gauge) on a downhill stretch out of Ann Arbor to Detroit area. best so far this year on a 500 plus tank is about 52mpg...its always something. taking a break on trying for 700 mile tank until my schedule stabilizes..

 

[94383Z71]

Wow...those are some good numbers! I've only had 2 or 3 400mi tanks

 

[joe truck driver]

600 plus tank

todays handy work. 8 legs, cash sale. true ...its not an actual 600 tank. add the two together. I just ran out of time. 52.46 miles per gallon. file attached is the fuel receipt. picture is 10 miles before fueling. would have come in at about 612 miles. still have one notch at bottom of gauge.

 

[Scot]

Joe, your results never cease to amaze me.

 

[Kuntryboy865]

Right now im at 37.8 mpg. When full im getting 404 mile tanks.

I think I am probably around about 60%highway now and I still cant complain about the economy of the 1.8

This past weekend was almost a 1000 miles of driving with about half of it loaded down with camping things and two bikes on the hitch mount rack. Still averaged 42.58 MPG for the trip. Next year I need to take a week to go tour and camp the U.P. though. A couple days wasnt enough.

 

[Blue hedgehog]

I'm glad I don't pay for the fuel.

Just took delivery of a 2014 turbo auto Sonic sedan, LT trim and standard 15-inch alloy wheels. And some gas numbers to report. A predominantly highway tank, typical speeds 69 to 73 mph, AC on continuously, still running tire pressure I was provided with at the dealer, but including an hour and a half of city or badly delayed road construction driving, and the two segments of travel broken by an overnight stop; 437 miles, Holiday brand 87 octane gas fill, of indeterminate ethanol content because it was Minnesota which does not require labeling, 39.14 mpg based on a subsequent fill of 11.164 gallons. This tank brought total mileage up to just over 1800, so we're past the break-in. The DIC showed 42.1, which is a much bigger deviation from the hand calculated figures than my first four tanks, and I'm curious about why that would be. It was very hot weather for this tank, so evaporation, perhaps, or the heat (mostly upper 80s to mid 90s indicated on the MyLink thermometer) simply throwing off the DIC?

 

[SuperFudd]

I have not reset in about 3 weeks of driving locally here in Union City and Fremont with very little freeway. The DIC says 24mpg. OK by me.

 

[94383Z71]

So I made a trip out to Michigan's Adventure yesterday, 164 miles each way. Four adults (two couples) totaling ~850lbs and an extra 100lbs in stuff doing 70MPH down the highway and A/C on light (85*F ambient) I avg'd 33.8mpg, which would normally be about 38-39 with just me.

My DIC tends to be off be 2mpg or less, fyi. These cars are very weight sensitive.

Ran 93 octane, trifecta tune, intake, lowered and 35psi in 215/50/17's/
