WC RT Engine Oil Consumption.
When the '14 RT first came out, there were chorus of owners saying that the wethead RTs don't burn any engine oil at all! I have to say, that I was one of those people. However, I had ridden the '14 RT for just a little over a 1,000 miles before it was returned to BMW, and I had gotten the present '15 RT. Now that I have 6,000 miles on my '15 RT, I have found that the statement of the wethead not burning oil is not exactly true! My '15 RT have burned some oil. Very little, admittedly, but the oil level did go down. The bike was serviced by the dealer at around 1,000 miles, and the oil level was right at the very top of the sight-glass, when the bike is on its center-stand. I check the oil level after every rides, and hadn't noticed the oil level going down until about 2,000 miles ago. I am not saying that it wasn't burning oil until 2,000 miles ago, but just that it hadn't been noticeable to me. Right now, the oil level is about 3/16" down from the top of the sight-glass.
This is NOT an issue at all, but I am just curious - how many of you wethead owners have noticed this slight oil usage?
An interesting side note is that, when I took my RT back from the dealer after its service, and the oil level is at the top of the sight-glass, my low speed gear change had become very noisy. That was not the case prior to the servicing, and the oil level was near the center of the sight-glass. We have had many discussions about the oil level vs. smooth gear change in other threads, and so we shouldn't rehash it here. The interesting thing that I have discovered is that, with the oil level about 3/16" from the top, my low speed gear change is now very quiet again! It helps to define the upper limit, for me, as to how much oil I should add when I do my oil change! I suspect that it will coincide with BMW's new specification of 3.8 liters vs. the old 4 liters!
