I did my second oil change at 4,500 miles switching from dino oil to mobil 1 and my oil pressure at idle is really low. At operating temp with dino oil my guage read 25 now with mobil 1 (both 5W30) it reads 12-13. Is this normal? It reads around 60 at cold start up same as before and around 45-50 at cruising speed same as before. Its an 05 with the 4.0 motor. The gauge is an autometer with electric sending unit. Just curious if anyone has experience the same thing. Also the tick is definately louder now when the engine is warm I presume due to decreased oil pressure.
Thanks,
Jon
