This filter was in use for 6 months And about 10,000 miles In a 2010 MB ML 350 With 90% highway mileage. It was the mobile 1 Cartridge filter Part number m1c 253 I was hoping some experts out there Can explain to me Why this filter Looks like it got Squeezed in the middle There is no tears in the filter. Did this filter fail or did it's job ?? Thanks In advance
