i also have a 02 440 sno-pro, this is a race animal, and comes with no warranty!!
i had the chance to buy a 03 440 sno-pro, but the engine tech at cats plant told me no way could it be trail ridden, although they may have a trail kit in january,
$8,100.00 out the door for the 03, lots of dough for a 440 you cant even trail ride, and comes with no warranty
but for the oil issue, i dont see how cat would ever know, why would your dealer rat you out, he would loose your buisness!!!
