Boiling Oil!? Help!

[causeofkaos]

the only time i saw the oil boil... hehe... was when i had the coil... hehehe... issue. i had to toil... OMG hehe... an hour and a half to OKC to get an oil... lol LMAO.. change and the coil... ROFLMAO... fixed. after that no boiled oil... 

im picking up what kinda reminds me of crazy as i read this

201oC is overheated on a 696.

Hi Howie, are you saying that 201 C is Ducati's high oil temp alarm level?  Even if it's measured at the head where it's circulating past and doesn't stay that hot for long,  201 C is  really hot!

Out of curiosity (and please don't tell me to "get a life"  because this is my life and I like screwing around with this stuff  ) I heated up a tuna can of 10W-40 Motul 300 Factory oil to just below 200 C, measured with an $800 Raytek MX infra-red temp sensor.   I previously heated the empty can to burn off any leftover tuna fish that might influence the highly scientific experiment     I don't know the exact temp that it started giving off visible smoke but it was well below 200C.   At 200 C it was very visibly smoking.

I don't think oil will boil.  I think it burns at temperatures lower than it would boil.  Reagrdless, an oil change and cooler should solve your problems.  If they don't get the oil pump checked.  I may not be putting out enough pressure.  Also, full synth is a little more resistant to breakdown at high temps like you're seeing.

Tell you to get a life, hell no!  According to the owner's manual, yes.  Would you probably smoke even the best synthetic oils at that temperature?  Probably.  My assumption,and we all know what that means, is the 201^o is not oil temperature, but a combination of oil and cylinder head temperature and (hopefully) Ducati got it right.

Google "oil flash point". Oil doesn't boil but if you heat it hot enough it will start to emit a combustible vapor. However, if it is mixed with water (i.e condensation or coolant leaking past a head gasket) the water component will boil  at 100C and the whole mixture will froth.

Running oil at extremely elevated temperatures will oxidize and breakdown the oil rapidly so you should change to a full synthetic that tolerates higher temperatures, and change it more often than the normal interval.

I think the temps here (161-175C, 322-347F) are hot enough that any moisture would easily have boiled out in very short order.  That bubbling may be some pressure in one area pushing though to another or the 'combustible vapors' pushing things around.  Either way, it's not water and it's way hot and needs to be sorted out.
