I had a similar conundrum yesterday..

my oil level had read as full... this oil only had 1200 miles on it, but it had 4 months.

i drained the oil close to five quarts. I was jack up a bit on the drivers side front...so i know all of it didn't come out. Also I left the filter on.

Anyway... i put 5 quarts back in..and it read a quart low? so i put another quart in and it is just above the full line.

i always change the filter out... but I don't have one coming in until tomorrow... will probably exchange then...

anyway... after doing valve stem seals, and the oil level sender o ring.. i decided to put full synthetic in the 260e. It was two for one at the auto parts store.

this car is headed to some warmer weather, and maybe some stop and go driving... so i put 20w-50 in...
