oil filter: UPF44 and PF44 the same?
I went to Pep Boys to pick up an oil filter for my next oil change and did not see any UPF44's. I did buy the ACDelco PF44 oil filter. Are these two the same thing or do I specifically need a UPF. Also, how many quarts do I need. 6 or 7? How many miles do you guys go between oil changes? 3000 miles seems to be the norm, but then again this is super synthetic oil.

The standard factory filter is the PF44. The UPF44 is a premium (better filtration ability) version. 3000 miles is fine, same as when I do it. Although a bit of overkill with synthetic oil, it wont hurt anything except your wallet (and the environment) to do it this often.

I use UPF44 but PF44 are a good filter.
I go by my DIC to change oil, and I wait until it is low (under 5% oil life remaining), usually about 6,700 miles for me. Mine is a 1998, Chevy says to change at 10,000 miles or DIC.
Later years went to 15,000 miles. Some people with early years reset the DIC oil life at 50% oil life remaining. I don't since I have an extended warrenty.
Mobil 1 will support these extended oil intervals, get an oil analysis if you want to prove it to yourself. I know changing oil is an emotional issue but it doesn't have to be, there is science.
Oh, you will need 6.5 or 7 quarts. Some later years had wrong dip stick and full is halfway, so if you go to top of line it will use 7 quarts.

I've read the UPF44 Filter (UPF meaning Ultra Perfomance Filter) is somewhat superior to the PF44, but either will work. :cheers:
