Review on ACDelco PF457G: Discover the Optimal Engine Oil Filter for GM Original Equipment by Kevin Jacobson

Good price for a good filter - OEM specs. Unlike some filter brands I've replaced, this one didn't come out warped and distorted (not that that's necessarily a good or bad thing). Many aftermarket filters come with an o-ring, this filter did NOT come with an o-ring which I don't want or need. If you're one of those people who thinks the sky will fall if this o-ring isn't replaced at every oil change, you'll need to order a PF457GO to get this o-ring. I change it every 3rd oil change which means I have a few extras in my garage. I believe a GM service bulletin once said that original factory o-rings would easily fit 40,000-50,000 miles (I could be wrong), although those normally found in a filter set seem a bit thinner and less durable. The filter I received said "Made in the USA".
