KTL is spot on.

Because the rings never seated they do not have a proper seat to the cylinder walls and therefore do not wipe the excess oil from the walls and are allowing oil into the combustion chamber. This is contaminating the mixture and also burning the oil with the combustion process therefore your excessive oil consumption.

If you are going to re use your original rings then I would clean the cylinders as Steve has stated and then install with either Kerosene or dry then carry out the high rev back down break in.

Let us know what the out come is. Good luck.
