On my 190E, i used Lubro Moly fully synthetic 5w40. Excellent oil and make the valve lifters less noisy when cold starting.

Ocap, what type of driving do you do?... freeway?.... city?.... short trips?

Hi, sorry for the delay:

Mainly suburban stop and go type traffic

The engine heats up quite alot during traffic conditions, like the temp will spike up to 100c + and then when you take it on a stretch of road where you dont stop, it slowly backs down to a little below 80...

oil pressure fluctuates as the engine heats up too, which i find disturbing (though i've been told its normal)
