Humor the newbie
A few quick questions:
1. What average temps are people seeing ? A cursory read through says around 200-220*F with sprited non-track driving. That is NORMAL. In fact, no one should be romping on the car much below 160* F, and ideal temp is most likely right around 200* F even.
Unless you are regularly seeing over 250* for extended periods, especially with a good synthetic, I doubt it's a cause for concern.
Clearly guys who track it are having issues, but there's a big difference between even very spirited road driving and track driving.
I mention this, because I wonder if non-track drivers need a cooler, and are just driving around with overly-cold oil that never gets to a good temp for most of their driving. That will hurt far more than it will help.
2. Any differences in reported oil temp issues (legitimate or chicken-little) between 2009 and 2010?
3. Anyone noticed any connection between following proper break-in, buring oil and higher oil temps? Poorly seated rings may be consuming oil, increasing engine tempss, and carrying oil temps with it.
I chekced with a a friend who works at Toyota and is an engine builder (yes, not Nissan, but really, how different could their methods and procedures be?), and he advised I follow the wear-in procedure, contrary to some people's (apparently erroneous) belief that this is all done prior to assembly by the factory...
If these are all stupid questions that have been dealt with before, please either direct me to a specifc thread (I did read over a few of the long oiltemp threads already...) or just tell me politely to shut the hell up
