OIL FILTER: UPF44 or PF 46
What's the difference in the two? The one I ordered from Fichtner is a UPF 44. I want to get one locally today so I can change my oil now. The local Chevy dealer says there are no more 44's and it's been changed to PF46. He also shows NO UPF. So, If I buy one now, it will be a PF46. Is that OK?
Thanks,
Jeff

You'll be ok. If I recall from previous posts, the UPF 44 is the "better" filter but isn't manufactured anymore. The PF 46 is more of a generic one. I went with the K&N filter. Got to be better than the PF46. Most auto parts stores carry them. Just my .02 ....

With either one you'll be fine. I run Mobil1 filters with no trouble.

Use either one - they both work fine.

According to the AC Delco web page the two oil filters listed for the C5 are the PF-46 and the UPF-44. Sounds like the PF-44's are no more. I've seen the PF-46's in local parts stores. I've only found the UPF-44's thru Forum sponsors...

I use the pf46.
I just had a thought....Anyone know what filter is used on the C6? Maybe thats why they switched?

The Ultragard UPF44 filters are also available from gmpartsdirect.com under GM PART # 25329389. I think Gene@FredBeans, a CF supporting vendor, may carry them too.
Hope this helps.

Well, I just changed my oil for the first time, at 700 miles. Bought the pf46 from the local chevy dealer. By the way, the original filter on my car was a pf44, not a upf44. So, I'm full of new oil and a new filter. Think it's time to play?

Oh, thanks for all the info, guys
