Chevrolet HHR, Wagon
#1442 of 1606 I don't understand
Apr 04, 2010 (3:06 pm)
I ordered a 2010 HHR LT2 ( still waiting for it ).
Something I don't understand here.
I was reading on the HHR and they say that premium gasoline should be used with the 2.4 L engine.
I presently own a 2005 Chevrolet Equinox with a 3.4 L engine and it runs very well on regular gasoline.
Why does a 2.4 L engine should run on "premium and the 3.4 L is o.k. with regular.
Something doesn't add up here or I missed something about engines.

Engine design. While premium is suggested for the 2.4 quite a few I believe run with lower octane (just have to watch for excessive pinging). While some don't notice the differance in performance, I do on mine when switching between.

premium is recommended...but not required.....we have an 05 Pontiac Solstice which I beleive has the same 2.4L engine...it too recommends premium for "best performance" we have always run premium in ours....with that said...as previous stated...just need to watch the pinging..should it occur.....you may notice a slight decrease in MPG as well....

Used oil tests/urban legend suggest that some makers put beefier anti-wear agents in the factory fill. Possibly to provide better protection during break-in. You can't use these anti-wear agents long time because they degrade the catalytic converter. When API switched to from SM to SL oil standards, there was a lot of concern that the "safer" antiwear agents weren't as effective. BTW oil tests post-switch indicate the SL oils are just as protective. But Honda factory oil tests show high levels of moly I believe.
So an early oil change at 500 miles to flush out contaminants is probably not a good idea. An oil change between 3000 and 5000 miles is probably about right for the first oil change. After than oil changes depend on patterns of use (urban errand running vs. long free flowing freeway work commute), local weather (temperate or frigid or boiling), driving style (never more than half throttle, 3/4 or more throttle), length of average trip, dusty regions). The computers built into current Chevy's and Honda's are supposed to be pretty good about taking all this into consideration. I generally change my oil at the 25% remaining life point. If you drive hard, try at the 50% remaining life point.
#1446 of 1606 Gas Tank Capacity
Apr 18, 2010 (4:24 pm)
I was searching the "net" for specs on the 2010 HHR and it says that the gas tank has a capacity of 16 U.S. Gal. and in my "brochure" (Canadian) it says that the HHR has a gas tank capacity of 65 liters.
Now this is where I need help, it doesn't add up...16 U.S. Gal. = 60.5 liters and 65 liters = 17.7 U.S. Gal.
Is it possible that the HHR has a different gas tank regarding where it's bound for?
How many U.S. Gal did you put in your gas tank when it was almost empty?
#1447 of 1606 What do you put in?
Apr 28, 2010 (3:00 pm)
I bought a HHR 2 LT to save money on gas and I read in another forum that the 2.4 L engine runs on premium gasoline or else you could damage the engine or you could hear a pinking sound coming from the engine.
Is this true?
Those with the 2.4 L. engine...What do you fill it with, premium or regular?

Regular for over 2 years without a ping.

Here is the 2010 HHR specs say: (if you have a different model year let me know) If the vehicle has the 2.4L L4 engine (VIN Code V) or the 2.0L L4 engine (VIN Code M), use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle’s acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard. If the octane is less than 87, you might notice a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service. If you have any further questions please let me know.

Good weather I use premium, I can tell the difference in the power with the manual tranny and like to make use of it once in a while. In winter I use 89 or 87.

In Canada, GMAC has their interest rate 0% for up to 48 months.
This interest rate is for certain models and the HHR is one of them but they don't say if it's for all the HHR models (LS, LT and SS) or if it's only for the base model (LS).
Anyone out there can help with this?
