Getting ready to do an oil change on my old Northstar Cadillac and bought an STP S3675XL but then looking thru my stash of filters I found this old Mann filterML 1010 that cross references to the car. I don't know how old it is but it has to be old and, well, can I use it?? It has been stored well and looks good (no rust) but the gasket feels a little hard. Pictures attached and thanks guys as always. If it's too old to use I can send it (and several others) to any member who wants them. My personal feeling is it's not worth running it if its more than a couple years old but I know its older.
