| I have a 90 NA 2+2 with 52K on it. I wanted to switch from the 5w30 I was running to something a little thicker for the summer without losing the "quick flowing" properties of the 5w. So... I'm giving the 0w40 Mobil 1 a chance and will leave it in there during the spring and fall instead of switching between summer and fall/cooler weather oils. So far, oil pressure is about normal 55-65psi at higher RPM and about 30psi when idling. That's good for me! Mike
