[Cut} Quaker State QS14006 8,500 miles/4 months

Pulled off our '99 Malibu with the 2.4L Twin-Cam. Mixed but mostly highway miles. Oil was Formula Shell with some Quaker State as topoff.

Did the job but I'm switching to P1's for this car since I've had ADBV issues after 5k miles.

yep looks like a Purolator Classic in a QS painted can.

I'm sure the waviness has no bad effect on filtration but their is something satisfying about the perfect pleats of a Hengst filter when I remove it from my Ecotec (as popposed to waviness in Purolators)....

Looks like it did it's job

thanks for sharing

Usually wavy pleats means water intrusion,did the car see shorts trips some idling also?? use any coolant??

 

[Virtuoso]

I thought that before too, but a previous UOA showed no water or coolant (filter looked similar). No coolant consumption. The car does see it's share of around-town short trips, too, so I guess I'm not surprised it looks that way.

In a few months I should have a P1 with similar miles hacked up, we'll see how it compares.

Basic condensation will not show up in UOAs if the sample is properly taken,i would say thats why the wavy pleats,this is why i like steel crimped pleat ends,its tough on glued ends when the pleats bend like that.

but other wise looks fine.

Good point. I've got another QS filter to post, and the seams on both of these are the "worst" part.
