My car did same thing, changed oil 8qts, drove 2500 miles on a trip no light. Car set for a few weeks high

came on, look for leak, none found , added 1/2 qt still had light. Added another 1/2 qt. still had light, Then i

remove a qt, still had light. Drove about 70 miles alarm came on said 1 qt low, added 1 qt light still on, then

added another 1/2 qt light still on, added another, lite on then alarm showed over filled. Got home and

pumped out 1 1/2qt added back 1/2 qt now all correct on dip stick. Took me a while to figure out how to read

dip stick. So now i have come to the conclusion that sensor is defective. Car ran fine during all this.
