My 1992 Silverado has the very odd habit of losing oil pressure the longer I drive it. It will start at about 30, or 1/2 on the oil pressure meter. As I drive it, it will drop until it gets to about 10 while at driving rpms (anything over 1k), but it will bounce on 0 at the stop light (300-600 rpms) and flicker my check engine light. Doesnt matter if the oil is old or new, and the oil level is full.
Why am I losing oil pressure as it warms up? I use 10w-40 synthetic oil. Has anyone else had this issue?
