Damn. Why didn't I think of this? Great job Ed!

FWIW, the central warning systems are getting old and they suck. Mine is unplugged. It was lighting the main warning light with out lighting the indicator lights to tell me what is was. I would suspect that system is faulty. As long as you don't lose oil pressure it's fine.
The other thing I thought was that when you accelerate the oil sloshes to the back of the pan away from the sensor. You could install an oil pan baffle. That would fix it if that's what's happening.

I thought I'd update this thread, which has now been resolved, in case someone in the future has the same issue, with the oil level light. I embarked on the journey of removing the oil pan, since my gasket was leaking anyway, and I really wanted to see what was in the oil sump. fortunately, it was clean, the screen was not clogged, no debris and the baffles were in place. I replaced the pan gasket and motor mounts while I was at it. Still, the engine oil level light came on during acceleration. However, it wasnt long before I realized my alternator was not charging regularly. Attempted to change the voltage regulator, but apparently I have the original Paris Rhone and was unable to get a voltage regulator for it. Long story short, I replace the alternator with a new one courtesy of 928 Specialists, and lo and behold my oil level light no longer turns on! In retrospect, the oil level light should only be lighting when the engine is not running (or charging), so I suspect the lack of charge but have left the oil level light sensor active. Lesson learned: oil level light coming on during hard acceleration is a default to signal that the alternator is bad!

Oil Level Switch -

Hey Jim - Glad you have sorted out your oil level warning issue. Many owners have had an assortment of electrical problems. I found my oil level warning problem to be in the connector plug of the Master Warning Unit (behind the side panel - driver's left foot).

Prior to starting the car - the oil level monitoring switch is the 1st line of defense against damaging the motor from a lack of oil. When the key is initially turned to the "ON" position - the "Master Warning Monitoring Unit" checks the status of the oil level while the oil is static. If the level of oil is LOW the master warning light (!) now turns on. Once the motor is started and the alternator voltage comes up - the "Central Warning Monitoring Unit" is told to ignore the oil level switch. This is because the slosh of oil in a moving car can no longer be monitored accurately.

Good Luck - Michael
