Oil gauge is at zero. Changed oil and oil filter. What else could it be?

Are you getting a check engine light? Either the gauge is broken or the oil pressure sending unit/wires are bad.

If it was the sending unit, the computer would know about it. So I'd suggest first checking the fuses, then the gauge.
