Yesterday just bought a 2016 Kia Soul Exclaim 2.0L from an individual with 105,000 miles. This morning I was sitting in the drivethru at the bank for about 15 minutes and I noticed the oil light flickering. Not on steady, but randomly flickering. As soon as I'd rev the engine, the light would go out. I came home and put the car on my rack I have at home and removed the sending unit and put a mechanical gauge in its place. My oil pressure is less that 10 lbs at idle with a warmed up engine. If I rev the engine to about 2000 RPMs, it will jump up to 50lbs. Does this sound like a bad oil pump? I really don't think there are major engine problems, there are no strange noises, and the oil looks fresh and clean. Does anyone know what the oil pressure should be at idle?
