I contacted K&N filter about their oil filter for the Chev HHR's, part number PS-7000. My questions are given below and below that their reply======
Note the PS-7000 is just an OEM type filter and NOT a heavy duty, high mileage rated, long service life or other special rated filter. It's just like the stock AC filter and other aftermarket filters. What you want is a synthetic, high flow cartridge oil filter, that provide great filtration down to 5 microns or lower and is made for high end synthetic motor oils. Shop around and when you find a great deal buy more that one... same for the oil.
PS: NOTE they say that... EACH K&N oil filter is tested to verify that they meet or surpass the requirements of the vehicle manufacturer. Just wondering what test that EACH filter get would be? Hopes this helps your HHR bucks go farther and used better. Regards, JC

--------------------------------------------------------------------------------
Please state how the oil filter PS-7000 for a 2008 Chev HHR with 2.2 is rated by miles.
Is it a high performing or high mileage filter rated at 1 year or 15,000 mile between changes? OR?
Can you give the micro rating for it... like it being rated down to filtering 3 micro (or such).
Is there any other oil filters for the car... does KN make any other/more oil filters for this application?
Thank you JC, User of your products and Researcher

Not big on answers, are they?

 

What would you expect from a graduate of one of India's finest English schools?

 

Go ahead and let me have it, I like their air filters, but will still stick to either AC Delco or Fram oil filters !
