1989 420 sel
oil pressure
i have a 1989 420 sel. just notice after recent oil change that after the engine is warm the oil pressure goes down to 0 when idling and up when driving. what oil do you put in spring and summer. they put 10/30 in mine. it never did that before. Any advise? thanks

Is your oil level all the way up? Oil pressure should never go to zero! Doesn't matter what oil is in there. But to answer your question, 10/30 should be fine, unless you are in a very warm part of the world.
