Brothers Of The Benz, All
If you love your machine, I mean really lover her, then DO IT.
My 1987 W124030, 103983 engine, with 176,000 excellent performing miles, and she's still original.
If I had changed over or started out new, possibly her engine will make 200 or 250,000 miles without even valve guide seals.
Say a prayer for her.
