So my local Automotive shop uses Pronto Chinese Oil Filters for doing oil changes... I went on a trip a few hours on the Freeway in my Chevy Silverado within 100 miles after the oil change and noticed 30psi Oil pressure on down fom my normal 42.5 Psi when on the freeway... Hot Idle down 5 psi as well... Changed to a Stp filter that I had in the Garage and bam back to normal Oil pressure....! Stay away!! BTW My truck used to be at 55 Psi 100K ago, I know it wearing out, but jeez, 12.5 psi down instantly, i knew there was a problem! I also normally bring them my own filter and oil., but this time, i was busy and needed to get it done right away... Live and learn! Going on Monday to report to the shop! They are good freinds of mine, hopefully they will change vendors in the future...
