I'm at 173,000 miles, I follow the service guidelines in the owners manual and so far no issue

JazzDad, I upgraded to a Mallory dual point distributor, and Accel yellow plug wires

 

LOL, I hope.

However I'm still puzzled by the GM service writer who wanted to flush my power steering fluid.

 

Never flush power steering or any other automotive fluids , it'll contaminate the water!

 

Anybody noticed this thread as gone waaaaay off topic from the 1st post ?

 

Oops , sorry George!

 

I run Valvoline 5W30 MaxLife Full Synthetic Oil, and a Fram Ultra Synthetic Oil Filter on my 2007 HHR LT 2.4. I change my oil every 7500 miles, or when my oil life indicator reaches 10% or less. I have 17700+ on her, and she purrs like a kitten. The oil, although dark, is never sludgy or gritty, the Fram filter works very well!! And I can purchase them on Amazon for about 7.50. The Max Life Full Synthetic oil is about 23.00-25.00 at my local Wal-Mart

 

Oh, so far off topic that it's time to close it with these final words....

HHR's have timing chains on all engine variants. 2.0, 2.2, 2.4, and that's as simple as we can make it.

If you have questions on required maintenance, or required service intervals, and your owner's manual has gone missing. Please click the link below to download a FREE copy of the manual for your model year HHR.

And the relevance to a timing chain is .........?
