With the higher heated oil  associated with the turbo, this anti flow-back can harden and warp, bypassing the protection of the filter.The UPF64R uses high temp silicone for the valve that stays supple throughout the life of the filter.My discovery started with a very large Chevy dealer putting the wrong filter on my daughter’s Cruze, and her boyfriend (later) trying to get the oil drain bolt off, finding it jammed on, (another story).Because I always change my own oil, I knew about the unique filter and saw she had the wrong unit installed. I called the dealer and the service manager insisted the PF and UPF were equivalents.  I did the research and contacted Chevrolet and was given the same answer.  I asked for a callback from an engineer and talked to him about it a week later. He promised to look into it.  This was in 2019.  In 2023, I was having warranty work done on the Equinox at a different dealer, was first in line for the morning and noticed the service manager arrived in a 2018 with turbo. Through conversation, slow day, she mentioned that her engine had to be changed within the first 40k miles and I mentioned the confusion with the filters.She got onto a GM service flash site and found a recent doc indicating never to substitute a UPF64R with a PF64. They finally got it right.  She mentioned that her car had a PF on it when it failed and she was going to have the mechanic put the correct filter on that same day.The flash also suggested no other manufacturer substitutes as “equivalent” filters may not have the correct material installed.Please check your owners manual for the proper filter.In the case of the Cruzes UPF64R, I always have to eBay order a couple for my and now my daughters car. She won’t go to a mechanic anymore. To this day, I can’t find the UPF in auto stores.</blockquote>
