%#)(%&*$ FRAM filter...
Dad took his 190E 2.6 to a small shop in his rural town for some service. They did an oil change and used a Fram filter.
He arrived yesterday and we took his car for a drive. Cripes, the oil pressure was near zero at idle and barely hitting 2 bar when loaded.
On a hunch, I checked the filter. Sure enough, orange garbage. I happened to have a filter from way back when I had the car, so I quickly swapped the Fram off for an OE filter.
Pressure back to normal.
Anyone wonder why you don't buy cheap junk oil filters?
