Excessive Heat 05 ZX6R after switch to Rotella T

The Rotella T Triple Protection is 15W-40, Rotella T6 is 5W-40...

So from this conversation, T6 will not heat up the bike as much as the T?
 
The oil should have next to no effect on the operating temp of the engine. Something else is going on or you are just noticing the temp more now.

Can you confirm T is available in 5w-40? All of my spec sheets don't show T in 5w-40, just T6 (which is non-energy conserving and JASO-MA certified). I wasn't able to find specs on 5w-40 Rotella T if it exists. If you find a jug check the API stamp on the back:

Its 15w-40. Shouldn't affect anything.
It doesn't say Energy Conserving

Nice! It's still not JASO-MA certified for wet clutches, like T6, but should be fine.

Some people run regular motor oil in their bike & no problems. Some people run Mobil 1 0w-40. What some people call "car oil"

You keep mentioning Clutch slippage. OP did not mention anything about his clutch slipping, even though he is running "car oil" or "truck oil"

The only thing that makes it fail spec is the ash content and the difference is so small that it shouldn't affect the bike operation. I've run T, Exxon 0w40 and pre-JASO-MA formulas of Rotella 5w40 syntheticwithout any issues. While higher oil viscosity may have some SMALL effect on the OP's temps, I'm betting it's another factor.. Still.. I'd switch to T6 just to space out the change intervals.
 
Dino oil will run hotter than synthetic. Then again t6 is not a true synthetic.

As for 5w-40 vs 15w-40, there is no difference except at cold temps. 5w provide better cold starts but that's about it. With this topic of discussion & with the weather we are having, there is no difference between the two.

So much misinformation in this thread. People spouting info they're not sure
