Was at Walmart this morning, yeah it seems that the Supertech MP filters aren't being restocked, couldn't find any MP9688. I think its a move to move volume of the branded filters on the higher shelfs.
The Endurance filters I checked today many have closed or thinly opened louvers. I'll pass until QC improves or they moved to punched holes or ecore center tubes.
I always got the MP10575 for my Silverado and Enclave, since it’s basically an AC Delco PF63 with a Walmart sticker slapped on it. Haven’t seen any at my store in months. But I also don’t ever see the ST10575.
I believe the Supertech white cased filter replacement for the PF63 is the ST12750 not ST10575...check that against what your Silverado and Enclave call for in a Supertech filter...agree that I haven't seen the MP10575 filter for our PF63 replacement for many months...
