I purchased (6) Mann ML-1015 oil filters in December 2012 from Rock Auto. These are for use in my 2010 Chevrolet Equinox 2.4L I4. I normally change my own oil, but just took the vehicle to the dealer to start an oil consumption test, which requires them to change the oil and filter to establish a baseline. The dealer is accusing me of never changing the filter, as they claimed the Mann ML-1015 filter that they removed was deteriorated to the point that the pleated media had holes in it. They gave me the filter that they removed and it is deformed into a slight hourglass shape, with a hole in one of the valleys of the pleated media. There is also a small amount of sludge visable in some of the pleat valleys. This is a cartridge filter, not a spin-on. The vehicle has 37,000 miles on it and has had the oil and filter changed every 4000 miles on average.
This was the second ML-1015 filter that had been installed in the vehicle. I don't recall noticing any problem with the first one when I removed it 3241 miles ago, but that's not to say that it didn't have a similar problem that I didn't notice.
I'd like to know if there are any known issues with this particular Mann ML-1015 filter in my application.
I'd like to direct this to Mann, but it's impossible to find any technical/customer support contact information on the web site.
Any thoughts?
