Holy Shit!... I'm really beginning to think this car is cursed. After a $1200 A/C compressor failure with a fresh oil change, I'm driving home and there's a new light, one that I've never see before, turn on. An amber colored "low oil" light.

It comes on after starting the engine (while warm mainly), sticking her in reverse and pulling out, put her in drive, and driving away the light turns off. It only comes on during inital startups......(as I was writing this, it became a rant, so to follow my rant, go here:
Rantings of Dough)
Now, I'm assuming that it's not due to the oil being low, cause then the light would be red. I'm guessing low oil pressure? But how? How much could this set me back?! How easy/hard to DIY?
