every once in a while maint required light flashes when i start car. the only thing i come up with is that i changed my oil with mobil 5000 awhile ago and its about 1000 from needing another change. and i have minor oil leaks so it is a little low. its at the first mark on the dip stick. can the comp. sense this. is that why the maint required light. all other fluids are good.
