6000 mile oil damage
6000 mile oil damage
(OP)
Over on the SAE forum someone posted " Has anyone noticed the damaging effects that the new 210 degree F thermostat presents? The bearings are running so scorching hot that full-synthetic oil blends are being burned black before 6000 miles. Yikes! "
1 - A couple of buddies have pretty new cars, and I don't think they mentioned "black" oil when changing.
2 - I don't think that bearings are the high temperature location in a passenger car engine.
Am I missing something?

be aware that not every full-synthetic oil is of the same quality - what matters are the specifications of the oil in terms of viscosity and performance. are you sure that the correct type was used in the incidents reported?

And your buddies should not be changing their oil, if there is a problem the dealers will not honor the warranty, and say there is no record of oil changes. The internet is rampant with stories about such things.

Separately I analyzed different factory-filled automatic transmission fluids with lots of service miles on them- some of the darkest ones retained better clutch performance than lighter ones.
Automotive engine oil formulations are generally about as analogous to jet engine oils as laundry detergent is to non-chlorine bleach, btw. There may be a little commonality in ingredients, but they're designed for much different purposes.
