Here's what they say, "Purolator PureONE oil filters should be replaced every 3,000 miles or 3 months depending on the driving conditions - or unless otherwise specified by the vehicle's manufacturer."
You can find it at:

Note that Pure One oil filters filter VERY well, but they do increase oil pressure, which may reduce oil flow due to the thick filtering media. I used to use a premium DELCO oil filter on my Corvette, but I changed to WIX because it was increasing my oil pressure.
If the higher quality P1 is rated for 3k OCIs what does that make the Classic Purolator then? replacement every 1,500 miles?
Oil filters are designed to withstand OEM specs, for the most part and the cheapest filter should at least be good for 7,500 miles.

I'll do the UOA yet to reassure the interval.
Personally, I'd get Mobil 1 while they're on sale and stock up for a few years worth. It will come out to be $6-8 bucks after discounts which is the same price as P1s at retail.
