#111 of 130 mpg, performance decrease by sda

Jun 22, 2010 (7:32 pm)

Recently I have noticed a significant decrease in performance and gas mileage. Granted it is a hot 90 degrees and A/C is on most of the time. Gas mileage in my normal driving has decreased from 27mpg to 23-25 mpg. Acceleration is sluggish, though the engine runs smoothly and is running in normal temp range of 190-202 degrees. I guess it is the temperature, or gas formulation. 2.4/auto. Had been using regular but stepped up to premium with little difference in either. Any ideas?

I just calculated my first m.p.g. on a full tank of gas "filled to the rim" on the starting point and on fill up (not the DIC figures but the real thing).
  My HHR is a 2010 2LT so the 2.4 L engine, it has 683.5 milles on it, still on "break-in" period.
  Drove 439.7 miles with 15.29 Gal. of regular gas and my "Low Gas" signal wasn't on yet, still had 52.8 on "Fuel Range". This tank was 34% city / 66% highway, never went over 62 mph and religiously driving in the city avoiding red light and accelerating slowly and gradually.
   My result is 28.76 m/p/g
 
  Is this good for the HHR? It's almost impossible!
And people are telling me that after the break-in period it will be even better on gas than this. Wow!
  I can't imagine how far a person can go on 100% highway driving 65 mph using the cruise control.
  Anybody else has good or better mileage than this?
  It's almost unbelievable.

Having surpassed the 100k mile mark recently mine should be broken in by now
 
I haven't done any manual calculations lately but D.I.C. is running over 31 MPG in the warmer weather. I have been using A/C quite a bit or else it it could very well be a tad over 32 during the warm weather.

#115 of 130 Is this o.k. by laserblue

My HHR is a 2010 2 LT with the 2.4L automatic
 
   Are these figures o.k. to you.
 
   1rst tank I got 23.63 m/p/g driving 80% city and 20% highway.
   2nd tank gave me 28.75 m/p/g driving 60% city and 40% highway.
 
  We're preparing for our summer vacation with mostly highway driving, I should get something pretty good by these numbers.

Looks reasonable to me, can vary quite a bit. I think you will see some improvement as you get more miles on it (of course only to a certain point);

My 2008 HHR LS averages 28 combined and on highways 36 plus even when its topped out she still get 20 so forget prius or any other hybrid HHR is the way to go

#119 of 130 Power Window Lubrication by mike507

Jul 31, 2010 (6:33 pm)

I have a 2009 HHR and the power windows would not work. The dealer said a fuse failed because the windows were dry, and the I need to lubricate the window tracks with a silicon lubricant periodically so I don't burn out the window motor. I never had to lubricate power windows in any other vehicle.
 
Has anyone had this problem, and where do you lubricate so the windows don't have silicon all over them.
 
Thank you.

I too of the many, many vehicles I have had through out the years I have NEVER had to use anything on them. Tell him to fix them right or give you a guarantee for as long as you own the HHR he will fix at his cost any power window problems.
