I changed my oil about 1k miles ago and then all of a sudden the "Change Oil" light started coming on for maybe 10 seconds right away when I start the engine and then it goes away. It will periodically turn on and off again when I am driving as well, but never stay on for more than 10 seconds or so. I checked the oil level and there is plenty of oil. The oil pressure gauge is also not out of normal operating range. I am not sure what would cause this or how to resolve it. Any thoughts? Thanks in advance. --Adam - - - Updated - - - I forgot to mention, this is on a 2001 Chevy Silverado 1500 Z71 w/ 5.3L and auto trans.
