Key is at the bottom. "1" is the best rating.
Scroll to the bottom of the chart. The key is the last line.

Waiting for a call back on efficiency. PG techline doesn’t have info so he’s getting in touch with engineering.
I like the shiny end caps 
can't wait to see some ratings.

I’ve noticed that some oil filters have a flat gasket and others a molded “p” style gasket. Is there any difference in the mating surfaces that the different type gaskets will be applied to?

Sweet! Might just be my new favorite oil filter.
Thank you. For sure another quality PG filter. I like that they responded. I'll def try them. It sorta is more of the same, which is good
No difference in the filter mount. Any engine using a spin-one can use either base gasket design if the filter is specified for the engine.
Decent for a 20K mile rated filter.
Agreed. I'm not seeing the value for myself, over the Carquest Premium. But I do applaud them for continuing to innovate.
My CQ also is a p style gasket. Any input if one is superior than the other usual flat style?
Why would they change it to a p style; most filters are flat.
I'm just wondering if any knowledge can be shared about it. I myself can't think of if it matters. But if the p style has less material being attached, idk if that would be ideal
I think it's aka lip style.
I personally don't know but I would think that's inferior to the flat o ring. Less material against the block. And it almost for sure won't withstand more pressure than the flat.... especially bad for Hyundai and Kia

PGI may put P-style base gaskets on some of their filters that are specified for engines where the OEM also has a P-gasket on the base.
Here's some summary info found. Personally I don't like P-gaskets because it allows the OD edge of the filter can to dig into the filter seat. Yeah, it's outside the the OD of the base gasket, but I still don't like machined surfaces getting marred up. When I was using OEM Toyota filters on my Tacoma, I'd take some 600 grit sandpaper to the OD edge of the can to made sure it was smooth as possible and put a film of grease on it so when it made contact with the filter seat it helped cut down the marring factor.

Ty very much for that info!! *I'm thinking to myself* I bring my oil change to a shop....just another thing I'll worry about if they tighten the p ring gasket enough, and basically flush to the block...ugh. I can't change my own oil so it's another thing the shops can mess up on
