Rekluse/Oil question

I tried to search this question. There are many!! posts about oil etc but I didnt find any specfic answers about the internal engine side effects. I apoligize if its a " Dead Horse " lol......I have an 09 YZf450. I just ordered a Rekluse clutch to run. The Rekluse people recommend the Rotella T. Any bad effects or opinions/experence etc with running this type of oil with internal engine?

I installed a Rekluse Pro in my 07 when it was brand new. I always use a hour meter on all of my bikes. I put 83 hrs on my 07 using synthetic oil and changing it every 6 hrs. I installed the same clutch onto my new 08 and ran it for 108hrs with the same routine of service and synthetic oil. Then I bought another 08 and installed the same clutch on that bike. I ran it 93hrs, same routine.

During all of that time I never had to adjust the clutch and never replaced any plates. I race constantly doing everything from ISDE qualifiers, moto-x to National Hare and Hounds. I recently sold the clutch with almost 280hrs on it for almost what I paid for it and bought the new Core EXP clutch for my 09. I have nearly 20hrs on that bike still using synthetic oil.

I don't understand why Rekluse insists on Rotella, but from my experience it is not needed. I always use Maxima synthetic oil.

Thanks Jeff, I appreciate the info............. This Forum is a great help. I am glad I ran accross it.

Why not pay half the price for oil if it does the same job?

If you are referring to paying half the price for Rotella vs. Maxima, the answer is actually that it doesn't really do the same job, at least, not for as long a time. Rotella looses its viscosity to shear in the transmission very rapidly. It's good while it lasts, it just doesn't last. So when you pay half as much but have to change it twice as often, it doesn't pencil out well.

I do a lot of endurance type events. For example, at the Idaho City ISDE qualifier I can spend anywhere from 5-8 hrs on the bike in just 1 day. I always ride both days and can change the oil at the end of the 1st day. Using Rotella I would have to stop and change oil during the day and that just won't work for me. Even a desert race can vary from 2-6 hrs. depending on the course. If my bike has 4.5 hrs on an oil change and I have a desert race to do I will go ahead and change it. If I have a moto-x to do I would probably wait until I had 6 hrs on it. Plus synthetic gives me a small cushion if I find myself running longer than 6 hrs.

Bottom line is that even if it costs more, it is worth it to me.

Your reasons for selecting an oil as durable as Maxima are correct and valid, but it's not the fact that it's synthetic that gives you that edge. Rotella Synthetic, as well as a very large number of other high quality oils, particularly automotive engine oils, also lack the ability to resist viscosity loss when used as a transmission lube. Synthetics do have advantages in resisting thermal degradation, and some other things, but the viscosity loss happens so rapidly that these other attributes never have time to matter.

Those are good points, thanks gray!
