On my way home on a 3 hour trip, oil pressure light came on early in trip and stayed on, and oil pressure gauge was jumping from 0 t0 80. Stopped driving, checked oil level, which was okay. Then noticed some oil leakage on ground. Is being towed to GMC dealership now. What is likely the problem and can it be fixed in 1 day?

Oil level okay when checked-could be just the oil pressure sending unit acting up needing replacement. If there's a problem with the oil pump and engine bearings you'll be hearing knocking noises.
