    40 is fine. For comparison mine, once warm, idles at 20 psi. and 40 off idle.

    So how high is too high? Just curious, the girlfriend's TJ idles at 40 but it goes to around 50 when we're driving around. If I were to switch to a higher weight oil for summer, would this make the pressure too high?
