So driving the '86 300SDL for the last few days, I've noticed an irritating trend with the "Low Oil" warning light. Once the engine has reached operating temp, it will come on with any sort of long sweeping turn, or any sort of hill climbing.

When the engine is cold, this never happens, only when engine is hot. Oil level is fine, about 1/8" below the "Max" fill mark. The engine is burning a small amount of oil, but in ~500 miles, the oil level hasn't moved an appreciable amount (not enough to tell a difference in level).

So the question.....do the sensors wear out? Is it just a float or something in there that could be coming apart? Why would temperature have anything to do with the behavior of the level switch? Should I be looking for something else instead of the level switch?

Help! Having that flashing light coming on every 30 seconds is about to drive me nuts! I live in an area that's nothing BUT hills, so this is truly an irritating problem, especially considering the oil level is fine!
