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!

12,700 here, Zero oil usage but I have to admit I don't think I've looked as closely as you have.

Re: WC RT Engine Oil Consumption.

Seems like I go from the top of the ring to the bottom over the course of 6000 miles. At which it's time for a change/refill. This has happened 4 times so it's repeatable. So yes it burns some but not enough that I need to be constantly checking it.

Not as good as engines from the Japanese, though - for some reason they show no drop at all between oil changes. Applies to Honda, Kawasaki, Toyota, Nissan.

Re: WC RT Engine Oil Consumption.

I think it's unusual to hear about a water cooled boxer burning oil and common to hear about an air/oil cooled one burning some oil. I think there is one rider on this forum that has experienced it. Teach may be? My 09 does a quart every 6k. That's acceptable to me, but I wouldn't mind less oil consumption either. I don't think there's a lot to nitpick with the newer RT/GS. GT/L, probably, depending on the year and luck.

Re: WC RT Engine Oil Consumption.

I have 14,000 and no oil use or value adjustment needed. there maybe some drop in the sight glass but it is less than 1/8 or 1/16 of an inch if that at the oil change time. The babe has run well over the speed limit and been out to the hot west. I am a revere not a luger for RPM.

If it excites you and scares the crap out of you at the same time, it probably means you should do it.

Re: WC RT Engine Oil Consumption.

Very interesting input! Thanks guy. I was just curious and suspected that most people may have not looked too closely at the oil level once that they had realized that the level is pretty stable. IMHO, the 3/16" drop in 5,000 miles is nothing at all, and in my case the cause for the oil consumption is probably related to how I ride. I tend to accelerate rather hard, when I pass slower traffic, before slowing back down to whatever cruising speed I was on.

Re: WC RT Engine Oil Consumption.

just turned 3000 mi and no oil consumption at all. Either before the 600mi service or after. When I took delivery oil level was at about 2/3- 3/4 level in sight glass, after initial change the dealer refilled to about the same level. Shifting is very smooth.

That sounds like a lot, especially for a wethead! My '07 burned oil at about that rate, just a little less.

Heck yes!

This wethead is going to get me in trouble one of these days! Typically, when I was riding the '07 RT, I might see the speedo hitch up into the 80's while passing, but on the wethead, I have been noticing tripple-digits many times, and I wasn't even trying!

Re: WC RT Engine Oil Consumption.

I fit in with the majority here Pad. Just under 10k on my '15, and while I haven't measured as analytically as you mention, I haven't ever had to add any or noticed level changes. I sure do like not having to always carry a quart on a trip like I did on the '08 👍

No kidding. I find myself not having to time my passes so carefully as I did with the LT. It's just look, twist, done!

Re: WC RT Engine Oil Consumption.

I've got 8000 on the '15 with no noticeable drop in the sight level glass. I have noticed that when I let the bike set for more that a couple of days, I do get a nice little cloud of blue/gray exhaust at startup.

Re: WC RT Engine Oil Consumption.

I would add that after being on a FJR for 8 years, an 07 RT for 14 months, and a wethead for four months, I find it much easier now to replicate the Feejer's "didn't realize I was going THAT fast, officer."

Being analytical is just the old engineer in me!! Curiosity is the other trait.

I have absolutely no complaint with what I am observing at all. My '07 wasn't quite as bad as your '08. It will burn about 3/4 qt between oil changes, and that wasn't too bad.

I really didn't realize that I was going so fast until, a few weeks ago, my helmetcam was tilted down lower than its normal position, and after that ride, I was reviewing the video, and the digital speed readout on the RT was very clearly shown! Holly cow, I was going THAT fast in simple passing??

I'm getting the same thing on my 2018 RT. Only I'm not going all of the way from the top to the bottom....I've got about 1/3 of the site glass window left. My dealer service rep told me that the oil loss could be due to the way I ran in the engine, but there was no loss at the 6,000 mile check and no loss at the 12,000 mile service. But, at the 18K service I noticed a big drop. There is no apparent oil leak...my garage floor has no oil on it.

Since the oil loss began after the first major service, of course I'm wondering if something done, or left undone then could be the cause. I'm ready for my 24,000 service in a week and if there is something I should speak to the service people about, I'd like suggestions. I'm not concerned about adding less than a quart of oil between changes. What I am concerned about since the consensus here is that the WC bikes don't burn oil is that this is an issue that may get worse over time.

Re: WC RT Engine Oil Consumption.

I think there's some variability between engines of the same type (Wethead/Camhead/etc.). My Camhead burns about 7 oz. per 1,000 miles and this has been consistent for the last 12k miles. Others report zero oil consumption. I'm not concerned about that level of burn at all. I do monitor it closely though so that if it increases I'll know. I've also had two Blackstone analyses done and both were right down the middle of normal for that engine.

Re: WC RT Engine Oil Consumption.

At 42K miles it loses maybe 2 ounces or so between changes which I do around every 4-5K miles now depending on conditions and time of year.

I've also had two Blackstone analyses done and both were right down the middle of normal for that engine.
I have a hexhead. It seemed to take forever to run in. Probably 18k miles. It got tighter over time. Maybe I use a quart ever 6k with it. Depends on the oil too. It burns the least with Mobil 1 V-twin, but Mobil 1 15w-50 is cheaper and works. If an engine burns more oil as it ages, that's not good.

Re: WC RT Engine Oil Consumption.

My last two oil changes on my Wethead RT were both over 7000 miles each. Zero added oil during that period. I start with oil about 2/3 up the sight glass. Oil level was still about 1/2 the sight glass at 7000+ miles.

Re: WC RT Engine Oil Consumption.

Terry - at 28k miles, I observed that the amount of oil that I lose, on my present '15 RT, is about what you observed. No need to add any oil, but the level drops a little by the time that I do the oil change at 6k.


Ponch - I used to have to add about 1/2 quart to my prior hexhead, in between oil change. However, you may remember in previous discussions that the amount of oil that one seems to burns varies a great deal between different bikes for the hexhead and camhead. Generally, one DO have to add some oil in between oil changes for those earlier models. Not so, with the wethead. At a guess, I strongly suspect that the water-cooling of the general areas of the exhaust ports (for the wetheads) has a lot to do with that.

Re: WC RT Engine Oil Consumption.

My 14' has no apparent oil burn after 120,000km and I change it every 10,000km. Every engine burns a little oil otherwise it would die.

Re: WC RT Engine Oil Consumption.

My 07 LT, my 15 RT, and now my 17.5 GS have NEVER used one drop of oil.

Again I will repeat I use the back drain holes at 9 and 3 o'clock in the sight glass as my fill line as reference marks. That is mid way in the red line fill circle. It is a very exact way to know. I fill to the top of those holes in the same exact spot it is parked and checked. I have done this because I have always been appalled at what people were saying BMW accepts as "normal" use.

I can also say I would say 98% of the time my bike is on the center stand. I have read something about bikes kept on the side stand blowing smoke on startup so is this where the oil is going?

I will add that EVERY time I ride my motorcycle it gets a safety check for speed and that means it must reach a Ton or better, and sustain that for as long as the "track" allows Not meant as a brag just information that these bikes were being run so if they were going to use oil they would have.

Re: WC RT Engine Oil Consumption.

You've all re-affirmed that your 1200 WC's don't burn oil. Thanks for that. But, I'm confused...like you folks, mine didn't burn at the 6K check or the 12K check. But by the 18K service it lost quite a bit and now coming upon 24K, it is down at least 20 ounces (I'm going to take it back to the point where it was filled to get an accurate count right before I take it in for service.) I'm left wondering what the heck could have changed after the 12K service that I might ask the service department about.

Presumably you are standardizing the test procedure? It's supposed to be checked at 5 minutes after turning off the fully warmed engine on the center stand on a level surface.

OK. Here's my take on this:

I've done it this way for almost two years. PITA. So what I start doing is paying attention to the oil level an hour (a day or a week) later with the bike dead cold after carefully checking per "the Procedure." What I've learned is that it basically doesn't change.

What I don't understand is this: if one is to believe that BMW tells us to do it this way because there's a reason, why is there no noticeable change in the oil level from at operating temp (after a 5 minutes shutdown) to dead cold an hour (a day or a week) later? I think it has to do with the air/oil heat exchanger valve opening and closing but since I don't notice much, if any, change in the oil level, why are we bothering to do this?

I'd just like a good explanation so my life can become fulfilled and I can start sleeping at night!

Yes...I do it "by the book". But with the kind of oil loss I'm seeing it really doesn't matter if it's 5 minutes or an hour & 5 minutes.

I've devolved into this practice as well. I guess their procedure is aimed at getting people to wait at least 5 minutes to get close to the reproducible level but I agree it stays very close to that 5 minute level an hour or more later. I have noticed some differences in the past perhaps at least I thought so at the time but if so it must have been insignificant.

That is bizarre keep us posted as to what they heck happened to your fairly young machine. Yours is the first I've heard of a rather sudden change in oil use. With no evidence of a leak does that suggest it's 'burning' oil, i.e. from worn rings? No blue smoke?

I'm curious (and perhaps lazy to try and look this up). What the heck is this and what does it have to do with the oil level in the sump? We've all heard that oil levels are to be checked when hot or cold as liquids expand some, but air/oil heat exchanger valve? Is this something that is even on a wethead?
TIA

It doesn't apply to wetheads. Pappy has an air/oil cooled Camhead.

Yes, in responding to this post I forgot it was related directly to a Wethead but, since this forum doesn't have separate forums for each subtype, I suppose it's not entirely incorrect. Regardless, apologies if I muddied the waters.

For the 2005-2013 RTs, oil cooling was used to supplement air cooling and a small radiator (whether oil or water cooled, a "radiator" can also be called an air/oil heat exchanger) was added just below the headlight housing. Those are the openings you can see in the Red RT in the site banner above.

Thanks Pat. I know he has a 2013 and this was a Wethead thread but didn't know what he was referring to. I have the RepRom for the RTs (K5x K50, K51, K52), and can find no part mentioned by that description or any word he used to describe it other than "valve" which comes up with too many hits to isolate easily.

Re: WC RT Engine Oil Consumption.

Hi Guys,
I just got back into riding RT's with my purchase last August of a new 2018 R12RTW. Past Experiences include a 1998 R1100RT "Oil-head" and an R1150GS also an oil-head.
Both of those oil-head bikes needed to be rested on the side-stand for a few minutes to let the oil glug glug down out of the oil cooler up in the intake area, then center-stand it and wait a minute or so to let it all settle out down in the sight glass..to get a consistent reading. We 1100 owners in these parts were taught this at new bike day at the dealer. These water boxers don't need that treatment best I can tell, but I still like the practice of center-standing it most of the time.

Here is the main reason I chimed in here. When I was handed my keys to the 2018 RT, of course I was all agog at getting a new bike and all, but it was like Deja-Vu all over again when my guy who has been delivering hunnerds of beemers a year for 20 years, went into his still standard litany of how I am to break in my new bike. Why? well same story as 1998, he sez, to get those BMW rings and pistons to marry up really really good and to never blow oil clouds and require a half empty oil jug in the side case most of the trips, you gotta break it in RIGHT. I do not know if the following applies to "K" bikes. just sayin.

So, how is it we do that? Well like years ago here's the common practice in these and probably other parts: First 150 miles from zero do not exceed 5ooo RPM, up and down on the revs but never exceed 5k if you can. That means keep it in the middle gears and do not use cruise control. ( What?? this baby has cruise control).
Next 150 miles up to 300 on the ODO, same deal but now you want to get it up and friendly with 7000 RPM a good bunch of the time. Vary the revs avoiding steady 3-5k cruising and no cruise control. Now it gets better, from 300 out to oil change time somewhere north of 600-700 miles on the ODO...Ride it like you stole it!! No steady speed cruising yada yada but (and this is the good part) Discover the rev limiter a few times! Yup, 9000 RPM and it shows you who's boss. Of course I didn't want to hurt the purdy new bike by keeping it in 4th or 5th. What a rocket ship.

IMHO this is probably the reason for "some bikes use oil and some don't" . We probably differ in the way we ride our bikes. Like the tech mentioned to RJPsRT above.

Why ones bike would start to use oil all of a sudden after a good history of not doing so, I can't say why.

Thanks NoelCP...yes bizarre. It's going in for the 24K service tomorrow and I just filled it to the same point that the shop did at 18K. It took 26 ounces of Advantec. At 18K I topped it off with 13 ounces, so twice as much this time. Interestingly, I don't see blue smoke. The bike has been sitting for a few hours since I topped it off and I just had my wife start the bike with me behind it in our garage. Then I had her take the revs up followed by her blipping the throttle hard. I couldn't see or smell anything resembling burning oil coming from the exhaust, but perhaps at this stage it's just hard to see or smell. I am mystified and concerned that with the bike warranty due to mile out late next summer that I'll be stuck with a smoker. At the 18K service, the service manager did not take this as serious concern. You know the old adage about first impressions? Well, this is my first BMW. It's loosing oil unlike my other bikes that never required topping off and on Saturday the digital display died. It's completely black. Everything seems to work...I know may way around the menu well enough to get my grip heaters on so the controls along with all of the headlights/signal lights, etc. seem to work. But I have no idea how much gas I have left...no idea of how many miles I've ridden since I reset the trip meter at last fillup. I count gears out of habit, but still like to see (rather than do the footcheck two-step) that I remembered to shift into first at a stop...that's gone too. I'm not looking for advice on the display...it's a warranty deal the shop will address. And if there's nothing else that could cause the oil loss I guess I'll have to arm wrestle the service people over this. I wrote to BMW Customer Service who refused to tell me the limits of what they consider to be "normal" oil use for the RT LC, but my service adviser told me at the last service that they had a memo from BMW stating it was 1qt. per every 1000 miles. If I had known that topping off 5 qts. between service intervals was considered normal by my bikes manufacturer, I'd probably be on a Gold Wing now.

As you have seen in this thread the norm is for little to no oil loss between changes, so this means something is gravely amiss w/ your RTW. Mine drops an ounce or two over 4500 miles is about it. That service advisor may or may not be reporting what the memo said but in either case it's simply a crock of sheet, as in completely atypical.

The guy is talking 'tosh'.
The number of Wetheads using oil is very very low. They are in a different league and the very odd ones that you hear about using oil, are literally the 'odd ones'. I really think it has nothing to do with how they were 'run-in'.

Re: WC RT Engine Oil Consumption.

In my case, I can't imagine that the "run in thing" is affecting my oil use. Two reasons that I feel this way... I live in the foothills of the Sierra Nevada and very close to 100% of my riding is in the mountains. The manual prescribes "riding during this initial period on twisting, fairly hilly roads, avoiding high speed main roads and highways if possible." Then it says: " Observe the engine run-in speeds" (keeping the tach below 5K) Well...that was easy as can be in the terrain that I live in! The second reason is that at both the 6K and 12K services, there was no oil loss indicating that the ring seating during run-in was successful.

I wonder if you got a bad batch of motor oil, missing some key additives? Hopefully someone w/ serious mechanical experience can chime in with some theoretical explanations for this bizarre behavior in your barely broken in machine. I'm from the late town of Paradise I'm sure we've shared a road or two on occasion. Fabulous roads all throughout the Sierra.

The various theories on break-in best practices range from 'don't need to do anything special they're all now broken in at the factory' to 'you need to run it like there is no tomorrow right out of the gate to insure rings are properly seated etc etc'. I took the middle of the road position and generally kept rpm <5K but after 50m or so started hitting 6K, then 7K for brief periods and all's been well for oil use for my '16.
