Default What MPG is your Lacrosse getting?

Curious what folks are averaging for both the 6 and 4 cylinder (E-Assist).

Just purchased new (to me) 2013 Lacrosse Leather with the 4 cylinder E-assist.
The power seemed ample, but nowhere near the V6. Since it's for my wife I figured the gas savings would be worth it.
Got home and found the average from the dealer was 18.9 mpg! Reset the value and after some 90% highway driving the average was still below where I felt it should be.
What does everyone get?
And is the computer even accurate?

Thanks from a new Buick owner.

Let's see. Getting 25MPG now, up from 23 and this is combination of city, country roads. Still under 3K on mileage and have had the car since last Feb. At least that's what the On Star is saying; on regular gas and 33PSI in the tires (varies a lot). We have a '16 LaCrosse with V6 and FWD.

I bought a '13 eAssist a month ago, and have driven about 1800 miles since then. I've filled the tank 4 times so far, and here are my calculated averages for each fill-up:

1. 30.88
2. 33.72
3. 34.13
4. 33.8

My driving is largely commuting, 29 miles each way with 70-80% highway, and that's where this car really shines. Since it has a larger, quieter, and nicer interior than my wife's '11 Accord LX, it does weekend family duty, as well.

The average fuel economy indicator on the dash is close to accurate, and my odometer reads 2.25% low, according to the GPS app on my phone.

I still have about half of tank 5 to go, and I've been pleased so far.

If speedo is off , check tire size to what is stick .

I run the tire air pressure to at least the max listed on the tires .

God bless
