Something Chevy Doesn't Tell You
By oceanhhr on
Vehicle
2010 Chevrolet HHR LT 4dr Wagon (2.2L 4cyl 5M)
Review
We have an HHR LT with the 2.4L Ecotec FlexFuel, automatic. Drives great. Plenty of pick-up. But no one mentioned the engine is NOT happy using the Ethanol gas we have to put in it!! To get decent gas mileage we have to put in an additive by Lucas every time we fill up! That's a pain. I would think about it before buying. Another problem is that the interior has MANY blind spots. You have to be extra careful to look more than normal to make sure you see properly. (Esp. for someone short in height.) It sits comfortably and the power driver seat works well. The round air vents are nicer than the standard louver ones. There are ample cup holders compared to many more expensive cars.
Favorite Features
Size, space for small car, good luggage space.
Suggested Improvements
Should find a better engine that will do well using Ethanol gas, since that's all we can find at gas stations. Otherwise, gas mileage drops as Ethanol builds up. Also need to eliminate so many blind spots.

Ethanol does not "build up". It does lower your mpg. E85 is not a good choice in any car that can use regular gasoline.

The engine doesn't require E85, it just has the ability to burn it. We have never used E85 in our 2010 HHR. Should run fine on regular 87 octane gas.

[non-permissible content removed] I have the same exact car as you. Funny thing this car can take fuel that has more ethanol than most cars and can take fuel with no ethonol also.. Hence the flex fuel car title... [non-permissible content removed]. It doesn't matter, where I live you cannot get the special E84 octane or E85 octane gas that costs less money :( I tried a full tank of E85 octane once, And then tried super premium E91 octane and the car gets 1.5 miles to the gallon better. Not worth it, since E91 octane costs $1.30 more a gallon And that Lucas additive you speak of is a ethonol conditioner. It's for non flex fuel vehicles to use once every 3,000 miles to clean your tank after using fuels with higher amounts of ethanol. Useless in a Chevy HHR... If you use this all the time, that means you wasted so much money and recieved no benefit. [non-permissible content removed]
