Oil pressure



2020 Chevy Silverado 1500
5.3l v8
Drove to Bakersfield doing mainly 75-80mph got outside of bakersfield and got a notice the oil low notice . And pressure normally stays around 60. She dropped to 50. I checked the dip stick. She is a hair under the line. No metal or anything like that in the oil. She had been doing the 75-80mph for a few hrs with no issues. No oil leak on the ground. Gunna check it in a few now that she’s sat for awhile. Anything else I should be looking at?
