I thought color is not an indicator of oil performance?
Color is more of an indicator of impurities, dirt, and possibly sludge in suspension. If your oil is clean when you change it out, it could mean a clean engine, or an oil that is not doing a good job of putting those things in suspension. I like having dark oil at my OCI, because I know all that ____ is coming out of the engine and not staying in there.
So it is an indicator of oil performance by that statement.
Of course this would go against those who say oil color is not an indicator wether an oil is doing the job.
Because particle suspension is part of the oil's job & yet they say color is not an indicator of how well an oil is working.
I'm thoroughly confused now...
Back on topic.
My 11 mile Mobil 1 oil is the same color as the residual oil on the value cover in the picture posted on the previous page. The Mobil 1 still in the bottle is very slightly yellow, but clearly much lighter than the oil in the picture.

YES THANK YOU!
Apparently, you and I are the only two is this thread that understand the true powers of the infamous Mobil 1.
What gets me is that you're the one with the most spotless engine on the planet, and yet you're being disloyal to the very product that got you there.
Mobil 1 is usualy dark in color when you are pouring it in from the bottle and a light yellow color on the dipstick. I have not seen any Mobil 1 that has not had a slight yellow hue on my dipstick. Like other have said the past conventional oil changes are going to dirty up M1 faster then normal the first and maybe second time round assumeing that that the engine is clean for themost part. Oxidation from the old conventional oil cintaimnets is what changes the oils color so fast. I also have noticed that oils that contain moly usualy darken faster initialy then oils that do not contain moly.
I tried to illustrate this point about German cars being a pain to work on in a thread called "Why European use thicker oil than us." I got flamed by a bunch of oil forum nazis swearing European cars, especially german, are the easiest to work on. I am glad I am not crazy and someone actually encounter the European attitude toward building cars that discourge people to work on in order to boost dealer service profit.
My 2006 Monte Carlo has the new 3900 engine in it, with some fancy new features (well, as far as GM engines are concerned) such as the oil-spraying jets for the pistons and the VVT system. Others have told me this engine shouldn't be hard on oil, but I just have a senseless gut feeling that it works it a touch harder than my old 3100 engine did.
I bought the car with 9400 miles, and changed it to M1 at 10K. At about 2K miles into the OCI the oil began to look black, and by the end of the OCI the oil had darkened considerably. I changed the oil out as per the GM OLM, in this case at ~7400 miles, and the oil was very black. The engine still ran smoothly, and had only consumed about 1/4 - 1/3 quart over the entire OCI, which I found impressive.
While the excessive darkening leads me to believe that the engine is giving the oil a workout, I'm still confident that the M1 is doing it's job and I will continue to follow the OLM for my oil changes. For an almost 7500 mile OCI, I was impressed with it's performance.
most likely nothing more than the oil that was left behind during the drain and then mixed w/ the refill of MOBIL 1 . Dealerships don't let oil drain long enough ( due to the time is money rule ) , plus depends on location of drain plug ( car lift is level , so less oil drains ). When use drive on ramps for D.I.Y. oil change the car is slanted so more oil can drain than when level , can let drain longer ( no quota to make ) , and will pour few ounces of leftover oil to help flush out more of the old oil in pan and let drain while longer before refill .
Well, sorry I didn't mention it. I do believe that if there is anything in suspension in oil that it will come out with the oil. That is cleaning it out of the engine and not staying in there. So, yes, Mobil 1 SHOULD be helping to clean your engine, or at least it SHOULD keep it from getting varnished or sludged. IMHO.
By the way, I would keep doing whatever it is you are doing with that motor.....
If oil turning dark is going to bug you, the following may prove helpful. This is a true story, and happened at the meeting of a car club to which I used to belong.
One of the car club activities was DIY oil changes; the club also owned a fuel injector cleaner, etc. So a guy comes to the meeting with a new model car, immediately puts it in the air, drains the oil, and proudly starts showing the pan of drained oil off. The oil is nice and clear and golden, looks like it just came out of the bottle......which, basically, it had.
This individual stated that since he drove a thousand miles a week on business, he "felt it was good for the car" if he changed O&F every week. I was pretty young then; if I knew what I know now, I'd have taken that oil off his hands, put it through some kind of homemade passive gravity filter rig to make sure there wasn't any debris in it from the drain, and then run it for a regular interval.
Looking back on it, it made him feel good, oil was about 39 cents a quart, so what the heck. I suppose the "what" was that the guy was an idiot....
