I have low oil pressure on my 4.7 1999 jeep grand cherokee about 10 to 15 psi what can I do car runs ok just worried about low oil pressure
Is that the oil pressure at all speeds or at idle? Read about oil viscosity at - -- http://www.bobistheoilguy.com/motor-oil-101/
spec. is 4psi at idle. 25-80psi at 3000 rpm with the engine at normal operating temp.
