I am switching my daughter over to GC and extended drains on her '02 Maxima V-6 with 40K miles. I just bought an M1 108 filter for the change. The size of the thing concerns me, it is about the size of the filter on my 2-cyl Honda lawn tractor - tiny. Mobil says it has 2X capacity of regular filters, but is it capable of holding enough for a 10K or longer OCI?
