One reason we run catch cans, you catch a lot of water and acid in them between oil changes. Mine is on the small side at 300 ml, I,ve had it just about full on my 13 2.0 when it was time for a oil change. The Sport seems to do a little better, but it's also got a lot less miles on it though the 13 runs really good and never uses a drop of oil between changes. Talk about short trips, I,m 2.3 miles one way from work so warming it up in the morning is a must most mornings, LOL
