Ken and Dan summed it up pretty well.
It is your decision, and it won't blow up as is.
But for the small cost of a couple 2nd rings, fixing it will fullfill your original goal of buying file fit rings in the first place.

Interesting that your 3000 mile oil rings "had no tension". Did you do a pull test with the oil ring in the cylinder? Did they go from 20 lbs to 2 lbs ?

Sometimes you have to give the world some time to get to your post...
