Hello,

I'm a newbie to this forum, and following your advice, I searched for an anser to my question. However, I dont know much about cars, so my simple query of oil pressure lead to over 2000 hits. I figure I'd just ask the question:

I have a '94 S420 andI seem to notice a direct correlation between the Engine Temperrature and the oil pressure when the car idles and when it drives. Starting the car in the morning, the oil pressure gague jumps to the max 3 and stays that way whenever/however I drive it. However, as the engine warms up, the idle oil pessure is lowered. Eventually, the engine will heat up tCo above 100 C (is that normal too? because it cools off ( about 90C) when you drive it, heats up when you idle in traffic). When past 100 C , the oil pressure is at 0 at idle and moves barely to the 1 when doing city traffic (35 mph). Is this something I need to concern myself with?

Thanks for your help!
