I suspected my ultra short daily trips to work, in cold start made for some dilution of oil by water and fuel ( very common).
So this weekend I finally was able to stretch the cars legs real well, up some hills at high speeds.
Heating up the oil and it looks like I got rid of the water+ fuel dilution in the oil.
I think so because now, my oil if taken on perfectly even terrain, matches the exact line of the full mark again.
I guess during winter its extra important to get the oil hot at least once a week.
