[Cruze2.0TD]

2014 Cruze Diesel, obviously automatic, 70 - 75 mph, fairly hilly terrain, 42 mpg on the two lane roads and usually closer to 50 mpg on the four lane roads. The slowing down, then passing and speeding back up really seems to hurt highway fuel economy.

2014 cruze CTD.

When it was warm I got up to 50mpg. Right now averaging about 40-43mpg according to the trip computer.
I keep tires at 42 psi warm per onboard computer.

Total round trip commute to work is 115 miles.
Trip is 1.5 miles dirt road with 10 miles surface streets rural then 45 or so highway finish with some urban driving to finish.
Commute to work is surprising direct Dirt road then left, right, left onto highway, two highway interchanges, off ramp, right, right at light, right again through one stop light, right again and I'm at work. The return route is almost the same. Except there is one extra right instead of a left.

Highway almost all long low grades up or down hill.

I find it amazing the difference winter makes on the CTD. I usually get around 46-48 mpg in the summer if I'm doing all highway driving, but come winter, same road, same speed, etc, I drop to 38-40 mpg. I'm sure that a lot of that has to do with winter vs summer tires, winter vs summer tire pressures (usually run 40 psi in the winters and 48 in the summers), and winter vs summer diesel, but it's amazing how all those things can equate to a 10 mpg difference.

A recent trip from Sault Ste Marie to Toronto (Ontario) got me an average of 5.2 liters per hundred km.

Which in US terms translates to about 54 MPG. I am pleased.

It'd be about 54 imperial MPG. US terms 5.2L/100km translates to about 45 MPG. US gallon is ~3.8 liters. Imperial gallon is about 4.5 liters.

Still though, 45 US MPG is pretty fantastic. The best I've gotten out of my diesel was 5L/100 km's.

2013 1.8L auto trans. With a/c on I get about 500mi per tank +- 20mi. In winter I get about 540mi per tank +- 10mi. I drive on freeway and city streets in AZ.

That seems really good for a 1.8L Cruze. How many miles per gallon is that working out to?

Last tank was 48 MPG (hand calculated) in my tuned and deleted 2014 diesel. Made it from Abbotsford, BC to Edmonton, AB on a tank (just under 700 miles). Lots of hills on the drive and I was averaging around 75 mph for most of it. Winter tires are on the car and only at about 40 PSI. Before the tune and delete to get 48 MPG highway, I'd need to have the summer tires on, stick around 65 mph, run close to 50 PSI, and be on a fairly flat road. I've now been tuned and deleted for about a year and am still loving it!
