OK, I haved been a searching machine these past 24 hours. I learned about Temp guages, Tach fixes, Poil change intervsals/T/C change intervals (or stretch measurement), 116vs123vs126vs...ect...

But, I was unable to find the answer to this question.

As you may know, I am the new owner of the Maple Yellow 79300sd. Now over 500 miles on it and not a single problem (go I hope not).

Anyway, when I purchase the car, the seller and I changed the Oil (as well as every other fluid and filter). The we also switched to Mobil 1 15-50 Syn. First Syn oil added to the car, ever!

So, in my Gasser experience, a quick lift of the dip stick, after 100 miles, would show fairly clean oil (still amber clear).

Well, when I checked the oil after ~100 miles, it was BLACK. Not dark, buy black! Questions:

1) Is this a Diesel thing? Oil gets dirty fast..
2) Was the engine so dirty that the oil is already black?
3) Is the Syn detergent so effective that it cleaned the engine already?

If this is normal, then no need to perform the next steps. If not normal, then:
1) Would it be helpful to do another oil change. Forget cost (50$-oil and filter) is nothing in the name of preventative maintenance.

2) If you recommend another oil change, do you also recommend I change the filter. Forget cost again...no concerned with a few extra buck to gain piece of mind.

Thank you all....

By the way, if this has been answered, I will not take offense if you send me the link to the post or simply profide a query string. I tried "Blakd Oil"...too vague!
