You can reset those settings? Wow.

Ok hi everyone this is my first post, and I bought a 'used' 2006 Chevrolet HHR in December of 06. Love it! But, I haven't reset the settings, but I average about 25.1 mpg on highway ... of course, I do about 80 everyday, so that could be a huge factor :)

Let me be the first to say

You will certainly find alot of useful topics here as well as its share of not so useful topics.

 

Well I filled up my tank last night, did the calculation based and I got a whooping 21.5mpg. I was running premium fuel (93 octane) in a 2.4 automatic. This is mostly fairly quick city driving on major routes without much gridlock. This number might be a little low because it has gotten cold here over the last week and I've let the car sit for around a minute to warm up, the roads have been okay with good traction and no huge slick spots to cause wheel spin upon first movement.

No, I'm not a lead foot and I don't floor the gas pedal.

I'm really pretty disappointed with these kind of numbers.

 

You do realize that the HHR is rated by the EPA at 23 mpg for city driving, correct? That 23 mpg is under normal, non-winter conditions.

Also, gas stations use a different gasoline mix during winter months, that is known to adversely affect gas mileage.

So you're driving in the city, having to stop at traffic lights, stop signs etc.---under Canadian winter conditions with a winter gas mix. Not to mention that you're probably warming up your engine a little longer because of winter. Even just another 30 seconds warming per start-up is going to hurt your gas mileage a little.

I would say 21.5 is about as good as can be expected under those conditions, and right at about what the EPA estimate would predict.

 

Maybe this is where I was getting disappointed or confused because the GM Canda website has the specs on the HHR rated of 28 mpg city but that's imperial gallons. In US gallons that is close to 24 mpg.

I was figuring that the consumption should be closer to 26mpg which is the combined city/highway rating on GM Canada. My driving is typically on free moving routes at speeds around 50mph.

 

I'm getting 27.6 around town---haven't had a long trip yet. My rental on vacation was getting 34 mpg. I'm in FL so a warm up time will decrease milage---that I don't much have.

 

Was getting 30-34 highway (confirmed by a 1200 mile trip) and 24-27 in town. (calculate the mileage every fill up from odometer/actual fuel input, the computer is shyt) They buggered around for about a month and we complained enough to have it looked at "again" where it was found to be a bad injector. They replaced the injector and sent us off with an "everything is all better" and now we're getting 22-24 highway and a hair off 18 in town. There is something very wrong with the fuel system in these things.

We're taking it back again and will post the results of our next round with the dealer.

This is an extended posting from my first. At its worst the mileage was 17.2 MPG highway. Things were this bad: https://www.chevyhhr.net/forums/problems-service-repairs-42/bad-fuel-injector-already-7049/

 

If you jump into the ocean off the northern coast of Maine in....say......mid-April, you'll get a full understanding of how cold can affect size.

 

You are full of it today
