This the first time I've run Mobil 1 and the oil started turning dark at 600 miles. Its even darker yet at 800. I've never seen another oil turn dark this quick. Is this normal for this oil?

I have a 97 Corolla with a 137,000 miles. The oil has been mostly changed at 3 to 4,000 mile intervals.

I'd also say that it's nothing to worry about. Some say the specific additive pack in oil, when exposed to high temps eventually causes the oil to change color. Others say it happens because it is actually doing some cleaning... maybe it's a bit of both.
I had an A4 a while back in which I started running M1 from about 5k miles (when the synthetic factory fill was dumped). It would always turn dark rather fast, even though technically there shouldn't be much cleaning to be done...

it's cleaning,run this one short, 2000 miles or less then run again,may take a few OCI to get to slow down.

I ran M-1 0w40 in my 2002 Saab 9-3 (2.0L) for 5k mile OCIs. I stood there and watched them pour the new oil in and it was dark after 500 miles on the new oil. And it happened with every oil change.
No worries.
Why such short OCIs on a normally aspirated engine?

My thoughts as well.
Don't worry about the color of the oil, that has little to do with anything.
And I would consider increasing your OCI's a bit, especially on M1.

It is fine. Lots of reasons why this is happening, none to worry about.
I don't think it is the add pack getting dark. It must be cleaning a dirty engine. I used M1 for 11 years on my last car, and it stayed surprisingly light-colored compared to conventional oil I used on other cars, even up to my 7K miles OCI. Because I used M1 on a new car from 3K miles onward for 11 years, the engine never got dirty.
