Oil Looks Dirty after oil change

Just had my oil and filter changed at the local dealer after 7500 miles with Mobile 1 0W30. I checked the oil level when I got home and the oil still seemed kinda dirty not as bad as before the change, but not the nice carmel color of my other cars. When I wipe the dip stick on a clean paper towel the color is more kind of black in color not real dark just looks weird to me. I had them pull a sample of the old oil and it was much darker than the new and I have sent it off for analysis.

What dose your guys oil look like after a change. Does this seam normal? Did they not drain it long enough? What do you guys think?

How many miles on your car? I assume it's still fairly new so I would think the oil should be more of a golden color if you just got it changed. Maybe they didn't change the filter or drain it properly. :eek: I have another car with 50k miles and the oil still looks pretty clean after oil change and 2k of driving.

I've had the exact same experience. I'm glad I'm not the only one. On all of my previous cars, the oil looked clear on the dipstick after an oil change.

I would guess that due to the way the internal structure of our engines are designed, only about 70-80% of the old oil drains out. Maybe an over night drain would make for cleaner looking oil after a change.

You could also changed it a few times at once to flush all of the old oil out, but that would be rather wasteful.

Fill, run the engine, drain, refill. repeat 2x. lol

I usually let my oil drain for 10-15 minutes before replugging and refilling. I ALWAYS change the filter with an oil change. Oil always looks very clean (golden) after a change.

i have the same experience. whether i get it changed at a dealer (have had it done by 2) or even one time i had it changed at a quick stop place in a pinch. after i get home and check the oil it looks dirty and unchanged. this is 11 model, 2 years old, but the result was the same even after the first 2-3 oil changes. i was concerned about it the first time as i noticed it after the quick stop change, but like i said, same result from dealer change after that.

Some of the old oil is trapped in top of cylinder head. More in the ladder frame and oil pump/balancer in bottom of engine.
