I recently aquired a 1991 190E 2.6.
The car has 96k miles on the clock. The previous (original) owner
had oil changes done every 3k miles.
The car drives v.well and the engine is quiet. However, I have noticed that the oil pressure gauge never quite reaches the '3' marker - even when cold.
When fully warmed-up - after a 25 mile freeway drive, the gauge usually hovers halfway between 0 and 1 at idle.
However, today, after exiting the freeway, the needle appeared to bottom out whilst idling. I shifted into neutral and the needle climbed to its usual position between 0 and 1.
Although the engine oil is clean, I plan to do a filter/oil change within the next few days. The plugs are also clean - light brown color.
What do you suggest?
