Have a 2008 Ram 1500 Quad cab 4x4 5.7, 93k miles. Recently check engine light came on, showing low oil pressure code. Replaced sender with new Mopar unit, reset light, code returned fairly quickly. I use 5-20 Amsoil that has been in for about 3k miles. I saw something about an ECU reprogram as the gauge never fluctuates or rarely goes below halfway. Is this a spendy dealer thing or should I look at other possibilities?
