I have a 2013 RT-S that seems to use an excessive amount of oil. I have searched the forum and it appears the 998 has an oil consumption habit, but then I saw people were adding half a qt between oil changes. I'm adding half a qt every few hundred miles. One post said consumption is higher if you have the stock crankcase ventilation system. What is the modified crankcase ventilation system? I'm hoping to find a solution to the consumption issue before having to sink a ton of money at a dealer or carry a case of oil with me when I go on a long trip. And because I will be asked. I check the oil after riding so the oil temp is up and within the 2 minute mark. I have no drip marks on my garage floor under the machine. Thanks in advance!

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Dealerships will tell you just about everything wrong with your Spyder is 'Normal'. Makes it hard to know when they are right.
I would say a quart in 2,000 miles is excessive. Though I am not sure what is normal.
Oil usage will vary somewhat depending on what oil you use, how heavily you are loaded, plus where and how you ride. Running hard and heavy at high RPM, changing speeds a lot on mountain roads will increase oil usage. I use about a quart in 6,000-6,500 miles. As far as I know, this is about average for most of my Amsoil customers. Maybe some will chime in here.

:agree: That's pretty much the amount of oil my 2013 RT uses when we're cruising/touring the open road & sitting at a steady speed for long distances. But riding like stink thru the twisties or playing hard on the backroads in the Hills uses about twice that, sometimes more. It seems to me that the amount of oil used depends very much on the amount of open/shut/open work my right wrist gets on the throttle, and it doesn't seem to be bothered much at all by running at high(ish) revs for long periods, IF it's done with a steady throttle. :dontknow:

I am runnin valvoline 10/40 full syth. now......I have tried castrol as well.Mostly used the brp oil/kit. ALL of em do the same.Aprox. 2 quarts at 5000 miles. Been this way since new. I try to keep the rpms at 4800 rpms.Shift at 6 and hardly ever go 7000 rpms. Never more than 8. 30000 Miles. Its still under warranty.Im goin to the dealership in a couple days.....Ill see what they say...AGAIN
I'm definitely not under warranty. It just seems a bit concerning. I filled it with oil, rode probably about 300 miles and my level is near having to add another half qt. Unfortunately I have quite a bit invested in this machine so I can't justify selling or trading to get a newer model. I guess on the bright side I have a machine that changes it's own oil.

This statement reminds me of another oil consumption possibility. Over filling your oil. This will definitely add to your oil consumption issues and can also tend to put oil in your air box.
If you are checking your oil level cold, before you ride, you are likely to overfill. Always ride for several miles before checking your oil level. I check my oil level right after I get back from a ride. On long trips I may check my oil at a gas stop. Hotel parking lots are not always level. This is the only way to be sure you are getting an accurate reading. And prevent over filling.

I am assuming that you're changing oil at the recommended 4,500 mile mark. This is important if you are using the BRP blended oil as it tends to lose a lot of viscosity around the 4,000 mile mark. Lower viscosity will definitely increase oil consumption. If you're getting a lot of oil in your air cleaner it will start to drip out of the right front corner. Since this is not happening I don't think you're losing any significant amount through the crank case breather.

I use about a quart between oil changes. I use BRP Blended oil. Bruce

Oil consumption should diminish as you get more miles on your Spyder. Though I still think what you are using now is more than it should be.

Last year, a buddy and I took our '12 and '13 RT's on a 5,000 mile trip and used about a quart each. We'd each done an oil and filter change before the trip, checked oil each night at then end of our days ride, and bought and shared a quart when both were near/at the add mark. Also did a Blackstone oil report at the end of the trip and Blackstone reported still usable oil life left. Still did a full filter and oil change after the ride.

What kind of oil are you using( brand and viscosity)
, and at what mileage was the oil change done?
Got my wires n plugs Ron.......THANKS! Question......I posted my oil and RPMS above. What are your thoughts on it? Should I run it at lower rpms? The tech guy at the dealership explained that the 990s were designed to burn oil. I was really taken aback about it to start with n had some REAL questions for the dealer. I dont mind topin it off as long as its not hurting the engine life. TY For your knowledge.

The 998 is designed to rev. It's hard to evaluate someones RPM range and shift points as there is no 1 Size Fits All solution. Under light loads with light throttle, running anywhere above 3,500 RPM is fine. Same for up-shifting to 3,500 RPM. If you are riding in hilly country or more aggressively, then a minimum or 4,500 is probably better. Running much over 7,000 RPM starts to drop your power curve numbers and is not usually efficient. But it won't hurt anything either.
Obviously, more aggressive, hard throttle, high RPM will tend to burn more oil than straight line cursing on flat roadways.

Vent modifications for 998
See post #7 on this link for modifications to the crankcase vent.
https://www.spyderlovers.com/forums...on-oil-catch-can-08-GS&highlight=oil+vent+can
Reduces oil loss and consumption. Parts are shown in the later posts.
There is another post dealing with oil level and the effects of vent modification.
I'll look for it tonight when I get home.
