Years ago on a different vtx 1800 I used it regularly, but had to add oil between oil changes 2, sometimes 3 times, changing oil at 5k. 5/40 full synthetic. I changed to full syn. motorcycle oil, 10/40 and no oil added between changes. I may be the only one that this has happened to as I didn't hear of this on this forum. Curious.
