Just an observation here by a curious BITOGer. At work today I did the break-in oil change on a John Deere Gator and John Deere commercial zero turn mower, both with Kawasaki engines. The Gator filter (left) is made in India. The mower filter (middle) is USA made, and the dealer replacement filter (right) is from Brazil. Just by looks and feel, the India made filter seems most robust and the replacement filter (Brazil) seems cheapest.
