Ok, whether it's cleaning, or a proprietary add. darkening quickly, or whatever, I dropped the fill of Sch. 5w20 (and Wisk filter) tonite and loaded it up with fresh Sch. 5w20 and new Wisk. We shall see how it goes. The previous fill was utterly black on the dipstick at ~3.5k - that's about as black as I've seen oil since 1995 when I pushed Amsoil to 25k once. I just couldn't leave it in there regardless of the "oil color doesn't necess. matter" motto. So, giving Sch. another go.
Schaeffer 5w20 - really black!

Eric - I had the same experience, and a few months later a CEL popped for a bad 02 sensor. If you have one that is geting lazy, it might explain a little fuel and some blackening. Just a thought.

Yeah, if this fill goes dark (black) quick - then I'll likely get it chked and/or UOA.
(and btw, I can't get over these cartridge filters - never had a car with one before - these things are pure pain - that's all - what a mess! If you can get one of these off w/o getting oil everywhere, then your a better BITOGr than me.)

I wouldnt worry about it getting dark on a first fill.. it might just be cleaning out crud.
I would sample/UOA the second fill at 5k miles or 6monthes and see what is going on.. then make a decision.
even then it could still be cleaning out crud.
both very dark and very clean oil bother me.
dark could be cleaning.. but what does oil that looks like new after 6k miles mean? its not suspending contaminants?
If your engine runs rich alot.. ie major short-tripping in winter.. this can also make your oil darken faster.

Yes, it's the first Schaeffers fill on the Mazda 6. It's got about 65k miles on the vehicle. You think I should dump early and repeat the cycle? - got plently of Schaeffers for a while.
Yes.
Just cleaning.

I started using Mobil 1 5w30 Synthetic, and my oil got very dark at 3,000 miles, after stopping the use of Jiffy Lube Pennzoil,and Conoco 5w30, Castrol Syntec 5w30 from an independent mechanic shop, and I am now using Quaker State Synthetic Oil 5w30 with a Pureone Oil Filter, and it is now very, very black after 5,000 miles. The Air Filter is a Purolator, and I checked it today, it looks virtually brand new since replacing it in January, 2009. Yes, there is a little bit of dirt on the filter, but it looks like, to me, almost new, and I think it can continue to be in-service for many more months to come. I have been using the Nissan Frontier, since changing the air filter, oil, and oil filter, on an almost daily basis.
I plan on returning to Mobil 1 in my next oil change and putting another Purolator PureOne Filter on my Nissan.
IMO, I will stay with Mobil 1, and the Purolator Air Filter and PureOne Oil Filter on my Nissan. To me those products have given me excellent service.
For my Mustang, I use OEM Air Filters, Oil Filters, Oil, etc., because it is under a Ford Warranty, once that ends, I will change to what my Nissan is now using because I am very satisfied with Purolators' Performance in every area.
My opinion only...........

Two customers with Toyotas running past 10,000mi. OCI and several running past 12,000 OCI. I'd say Schaeffer does okay for the cost in Yotas. By the way,the oil color in them all has been dark amber at those mileages with the engines hot. They were started on Schaeffer oils when they were new so the engines were clean. Two of the Tacos have clicked past the 150K mark. Guess Schaeffer oil really doesn't eat engine bearings after all...
Mokanic, hello again! I realize that oil in a cold engine seems to settle (or something like that) and is darker when chking a cold engine better starting than it is just after shutting off a hot engine. But this oil was truly black on the dipstick (and a black blotter test) even just after shutting off the engine while hot. I've seen the data and believe Schaeffers 7000 is fully capable of long OCIs with excellent results - but in this particular run, it just did what it did. Perhaps cleaning or engine issue. Looking forward to how this run goes.
