MPG by aliensporez

I have a 2007 HHR LS with the 2.2L and automatic. I have 42,000 miles on it.
 
In mixed driving (60% city/ 40% hwy) my average is 26.3 mpg. This is ACTUAL mileage, based upon miles driven and fuel filled at the gas station, this is NOT based upon the mileage computer which I've found is inaccurate (it displays an mpg about 2-3 mpg higher than actual). I keep track of every gallon and mile travelled on an Excel spreadsheet (it also helps me track oil changes and tire rotations).
 
Straight highway mileage is generally around 31 mpg (cruising 70ish).
Straight city mileage is generally around 24 mpg (45 mph)
 
I'm very happy with the mileage. Over Christmas I drove 1600 miles from Texas to Canada, and then another 1600 miles back again. In the HHR were 2 adults, 2 kids, a HUGE 15 cu ft Thule roof carrier full of toys and the back cargo area was full of luggage and my average economy was 28 mpg with my average speed around 75 mph for the full 3200 miles. That's pretty impressive considering the HHR had about 700 lbs of people and stuff jammed into it.
 
The only thing I HATE about the HHR: Acceleration can only be described as glacial.

Not going to measure any G's with all the stuff you are carrying, thats for sure. Still sounds like you're a happy camper. We me included have to give up those days of hot cars and learn to be satified with the good mileage and forget about the speed.

I read a few so it looks as if the 2.4L does as well or better than the 2.2L. If this is the case which is the better engine?

Of course the best engine is the one I have which is the 2.4 Seriously, I don't know which is the best engine. What is a good engine for me may not be for you. The SS engine would be the best but is it worth the extra few thousands you would have to pay. I guess that is why there are so many different engines out there as there is no perfect engine that meets everyones needs.

I have the 2.0L Turbo in my SS and yield about 27.5 mpg with 70% hwy and 30% city. These numbers are the result of moderate performance driving.
 
I could probably do better with a lighter foot out of toll plazas, but it's fun keeping pace with Cadillacs and Acuras. They never expect to be passed up by an HHR.

I am a very new HHR owner and I am having a problem with what everyone else in the world of hhr's is saying they get for mpg and what we are getting!!! I have a 2007 LT with the 2.4l engine. We bought it approx 3 weeks ago and in every other waywe love this car!!
We are even considering taking it back and utilizing our "30 day if not satisfied get a different car" option. Not because we dont love the HHR but because we are only getting 17-19 city and 25max highway! What can I do? Oh and We use cruise on the highway, and we ARE running the air in town AND on the highway.
One other comment. A gentlemen who owns a tiny car dealership swears to me that chevy makes a 100,000 mile spark plug!???? Told me if I dont believe him, call gm.Well I wouldnt even know where to guess to call.Has anyone ever heard of such a thing?
I only have one week left to make a decision on this car, and am desperate to figure this out.

There maybe an AC/Delco platinum plug that they say will last 100,000 miles like the Bosch 100,000 plug. Cadillac's and a few cars come with 100,000 mile plugs though I don't know if I would leave them in that long.
 
Your mileage could be a combination of a few things or just a couple. Have you tried a different brand gas? Some vehicles need to get their computer reflashed to fix problems like this. You could disconnect the battery overnight. This would reprogram the cpu's memory as to your driving style. This has helped with some cars. A sticking brake pad touching the rotar causing a drag can reduce mileage a couple mpg.

I think I should have got the manual! lol
But I didnt really have that option since we bought it used off a pontiac dealer lot lmao So my question is this: CAN We trade this car straight across if I can find a manual HHR with a sunroof? (the only 2 things we wish we had!**running boards would be nice too but doubt I will find them on a car with a manual shift since most people special order them with automatics**.) and IF I can talk the dealer into the same exact price?
 
I think the answer is probably a big FAT NO> but it never hurts to ask. lol
 
Thanks a bunch! in advance

I see this is a very old post but I am very new to this site . The difference in mpg w out air running is astonomical, to the tune of 10-15 mpg.difference.
 
We just bought ours so we dont have a whole lot of running numbers but so far that is what we see.
 
I am hoping your 2007 is still holding up well since that is the year our used HHR is, with a 2.4l engine.
