Q: Oil Gauge

asked by on August 18, 2016

Oil Gauge goes to zero. Light comes on. Changed the oil sending unit, cleaned the other part. When cold gauge works, after 15 minutes it goes to zero and the warning light and ding happens. Changed the oil filter. Haven't got to new oil yet. I got a Mopar sending unit. Checking with manual gauge this weekend, what else to do after that?
