And what was the Ford Service Bulletin solution for a flickering oil light at idle when the FEs were really hot? Just turn the idle up a bit and it will go out.

A quick note regarding the
Oil Temp of 270* Degrees
Conventional oil turns to Coke at 270*degrees... but now with Synthetics oils they will go up past 450* Degrees....
At 270* the motor breather will start smoking and smell just like oil burning... many times this happens when the air is not going thru the cooler and the motor just gets to hot.... more things could go wrong... but usually if you just kool the motor down you are OK...
With the
Synthetic oil .... the motor just gets hot and keeps running until you have a part failure. then you have to service the motor.
