There is no nickel or chrome cylinder in existence that doesn't use oil. Its physically impossible due to the bore being too smooth. No hone pattern to retain oil to prevent the rings from hydroplaning. As they wear to be even more polished, the oil consumption goes higher. It is bothersome but if it were me I'd just live with it until TBO if its running well. There is always the chance that the new cylinders may not have been honed to ideal roughness and so you might end up spending a bunch of $$ and end up not much better than where you are now on oil consumption.
