Does not always play well with others
I guess my Blazer has a problem then, because its 20k mile engine doesn't blacken within 3000 miles.... Wish I could say the same for my Sierra's 217k mile engine lol.
Show me a quart of you oil new uncirculated and a quart of you oil after 3000 miles and I guarantee that the 3000 mile oil is blacker than the new.
