#1 of 20 2.2 vs 2.4 differences
Dec 24, 2008 (9:09 am)
I'm possibly considering buying a used HHR.
Other than the obvious, can someone explain the differences in the 2 engines. Does the 2.4 require premium fuel?

No premium fuel for those two engines. Both highly regarded engines in the auto industry and race track.

Premium is suggested for the 2.4, if lower grade is used you just have to watch for knocking, many do use lower grade.

Defeats the purpose of buying for fuel economy if you have to pay more for the gas

There is always that fine line between econ anf pep too. I have a 2.4 but coming from a truck getting 24.5 in city driving by being a lttle careful is great yet I have that 179HP if needed. I have used both prem. and reg. and see no difference in mpg and just a very slight bit of power and that is questionalble.Running it normal, not being careful pulling away from lights etc. driving like the gas is cheap (it is) gives me about 22+

I don't have a lead foot and when I test drove a 2.4 and wasn't overly impressed with the pick up. Just wondering if anyone has drove both for comparison?

If you need to be impressed than get the SS and it comes with the 2.0 which is a little smaller yet.

The 2.2 develops 149HP vs 170 something for the 2.4. Premium fuel is suggested for the 2.4, 87 octane for the 2.2. I have a 2.2 with a five speed, and have never felt it was underpowered, but perhaps having a manual transmission helps more than I think it does. I would certainly buy the same setup again if I were in the market today.

You may want to try chevyhhr.net as they are a huge forum site and will have all your answers and some you didn't even know you wanted to ask.

This is a bit off topic, but our car(Homer- the wife hates the name!) has the 2.4 and gives lots of power for its size. In Canada we have a 10% ethanol blend and a chain called Mohawk/ Husky that sells 90 octane for the same price as 87. In my Scout, the performance difference is very noticeable. I try to use the 90 blend whenever I go on long distances with heavy grades. Even around town it helps on hills leading home, however, not enough to offset the discounts I get at the local Superstore Gas Bar in the Scout that is- the HHR gets the best at all times, unless there is no option when traveling; then you must take what you can get.
