usersmanual you had your say we all know how you feel, you don't need to keep defending your position. I change mine in the fall as there are acids and such that"can" do damage to a motor. I also change the fuel filters once a year in the fall also, may not need to but I never have had a problem. OH do the same on my gasser now.
