MPG going up on my 2012 1.8L Sedan

[$ub$onic]

Well in the city its hard to go over 3k.. im always around 2 or 3k

I'm rarely in the city. 90/10 hwy city

I hit 40 mpg quite often in my 1.8 5 spd but like $ub$onic said I'm almost all highway 98/2 . Car is bone stock no mods other then appearance.

Don't give up hope! This was me today on a 20 mile trip on the highway with the ac on(cause my lady was in the car haha). I got up to 41.5 then when I got off the highway it went down to 36.5 by the time I parked in my garage. Also my mpg meter has been correct with my recent hand calculations

I average in my 5 speed around 35-37 mpg. I've pushed 43 Mpg out of it before from babying it. 1.8 with no mods.

The other day I got above 90 miles per gallon on my 1.8 automatic... But I was kinda drafting off this car and my foot wasn't on the pedal... If only 90 mpg was possible

That's what I call a "rolling reset", completely worthless for measuring fuel economy but it's neat to see how high of numbers you can get. I regularly get infinete gas mileage when slowing down (999.99 mpg on the UG)

It would be nice to get 90mpg per tank, FTW.

average so far

1.4 turbo auto. hatch

1st tank 29 mpg
2nd tank 30
3rd tank 32

numbers are actual. not from gauge. (gauge reads high 1-1.5 mpg)
same driving conditions
currently on 4th tank

Here are a few tips to get good fuel economy out of your Sonic:

Stay at or below 75 MPH on interstate highways

Accelerate normally, but not aggressively

Slow down way ahead of a red light and coast to it, do not drive to it at high speed and then brake heavily at the last second (I see this all the time)

Avoid jackrabbit starts and full throttle acceleration

Use major brand gas (BP, Chevron, Mobil, Sunoco, etc.)

About every 3k miles put a bottle of Chevron Techron into a full gas tank and run until nearly empty. This will keep your fuel injectors clean.

Fill up your gas tank when 1/3 full. This helps to extend life of the electric fuel pump which is cooled by fuel. Do not run the tank almost empty for this reason, as the pump may overheat

Change your oil regularly, same for the air filter

Keep the tires inflated to proper pressure

Warm up the engine after a cold start before moving the car

Periodically check your brakes to make sure you do not have a dragging caliper on your disc brakes, or a dragging brake shoe on rear drum brakes

If you have a manual transmission, avoid shifting over 3000 - 3500 RPM

This works for me.

Warming the engine up is pointless and wastes fuel.
Fuel injector cleaner is worthless.

That is all I have to add.

I Wait till it comes off high idle. Anything longer is, like you said, a waste

I have seen Injector/carb cleaner work( to a extent) but I think it's pointless in a new vehicle like this
