Engine cold, start and let idle, oil pressure drops until warnings come on. After engine is at running temp oil runs at 60 psi, when at idle it may drop to 40 psi after it is hot

dropping oil pressure when hot at idle is normal. have this checked out manually with a gauge. it may be an electrical issue or the dash may be going bad.

like I said check pressure with a gauge. also use a decent oil filter as that can cause problems. Oil filters form china likemotor works are pure junk an ddo not do much good . try a brand name one like ac/Purolator/wix/napa
