I change my oil every 6000 mi. with Amsoil 15w-40. At every oil change the oil is nasty black with soot. After I fill it with fresh oil and run it for a minute I check it again and its all ready black again.
This is normal right? Should I be concerned?
Will a bypass filter help?
Yes absolutely normal and yes a bypass will help somewhat..no need to be concerned the CR's are like that....

Black oil....normall!!! Changing Amsoil oil at 6k intervals.......waste of Even without a bypass, Amsoil oils usually go much longer than that and are still analytically "good"!! And I don't run Amsoil engine oil either!!!!!
I wouldn't go that far... I have been around diesels for more than a day or two and they dont all do that... My dads 3406 Cat would stay golden for hundreds of hours with a bypass.... The HPCR is a different breed based on in-cylinder EGR.
a bypass wont clean it up.....trust me i have one. but what i t will do is filter out all the soot in oil down to like 3microns or less. i am able to achieve 30,000miles + on the same oil. could go longer but that's just were i like to change. good luck.
Mine oil always turned black right away both on my current truck and my last truck right after the oil change.
But since adding a Smarty my oil has been much cleaner, I don't know if I should be happy or worried that something is wrong?
I am at 7500mi on my synthetic and getting ready to change, and yet when I pull the dipstick the oil is still fairly clean. I can see all the the cross hatch and low line no problem . I will try to take a pic and post it.
