For All The Rotella T Folks...I have a ?

What, where, how UOA? Info Pleez.

Blackstone Labs is usually the common place.

Yep Blackstone Labs.  I usually do a yearly test on each bike.  Only problem I have ever had come back as a problem was my SV with Flatslides, it gets Fuel in the oil.  Every time you touch the throttle and its not started  those accelerator pumps dump fuel in the jugs.   So I change that one more often.  I would have never know this was occurring if not for the analysis.

Well that is the case and good question.

A lot of AMA teams (including this one) are using Motul.

Some of the best engine builders in the AMA paddock are the ones who told me. And yes I've tested it myself  

I don't need a published test, if you do then you can wait for it.

If you want to be a dick that's your choice, I always use my brain. 

Believe what you want, do what you want, it doesn't make any difference to me.

I wasn't trying to be a dick. I also do not have all the answers, and I can only speak from personal experience and speak about things I've seen. I apologize if you interpreted my comments that way, unfortunately the internet has a way of taking the sarcasm out of what is typed here. I'm glad that you feel as strongly as you do about the oil you choose. Good luck to you and your team this year! I hope that the products you use will meet and exceed your expectations.

I don't like running oil very long in a race bike that has a wet clutch. I'm always amazed at how much clutch fiber you can see if you take the time to look in the filter a few real hard starts.

Granted it should all be caught by the filter.......but I guess I'm just anal.

Totally agree, change mine after every race weekend, filter as well. 

Someone mentioned above about seeing results of fuel contamination after an oil lab test.  Never had a lab test done but found that comment interesting. I always smell race fuel when changing the oil so I was already convinced there was contamination.  Race fuel is very corrosive so I can only imagine what is going on when you continue to run contaminated oil.....can't be good.

Someone also commented running their oil an entire race season!  Holy cow!

So if my oil sample comes back good it's wrong?

Didn't say that,  not sure what the test includes and what the criteria is for classifying used oil as good/runnable. I just can't imagine not changing oil the entire season.

Based on what I know (and I'm not saying I know it all, just stating what I know from personal experience) happens inside a motor/transmission during racing and the fact that there definitely is contamination of the oil during use, the idea of running the same oil an entire season is mind boggling.

UOA will tell you what's actually in the oil, and compare that to what the oil is supposed to be.  But also compare it with a proper Total Base Number that can tell you if the oils is shot.

Well I can understand why you would think that.   I used to think that and I would change often.  But someone saying they change every weekend to me sounds like too much.  I really think its a big myth now that I started doing the testing.
I plan to run Rotella 5-40 in my SV for the season racing and track days and change every three weekends keeping an eye  on the oil level and for fuel.  I did just rebuild it this year only for the higher compression.  The pistons that came out looked great!.    BTW Motul makes the clutch slip in that bike. 

In the RC I run the Mobil 1 15-50 starting last year mostly because it gets so hot and runs at around 210F.  Will see what the test says. 

In my 1098 I havn't decided which oil I will run but yea I will probably change it more than once a year ;)
BTW the 1098 and RC I do not race.  Just track days.
