I have had a low oil pressure alarm on my 2005 Suburban on several occasions. Only when cold, and when idling. My mechanic has checked everything out and says he can fond no problem. Replaced the oil pressure sending unit. Still happens - though not always.
The vehicle has 248,000 miles on it and it runs perfectly, but I am concerned about this warning. Anyone have any thoughts? I’d like to keep it running well and we take long road trips. Don’t want a disaster!
