    Since it appears that some of us have different ideas on what's normal and what isn't....if you're really concerned, send a sample out for analysis. It's not expensive, and it will give you peace of mind. You might actually find out things that you didn't know. If you do that, please let us know what you found out. Good luck!

    10 w40 brad penn and mine was darker than other oils, not black but fairly dark for the amount of miles it was run. I switched to Valvoline for older cars and it seems to hold its color much better.

    Maybe brad penn traps carbon way better than other oils? Honestly after I pulled dip stick after changing oil I said same thing, wow that went black fast. My new motor it hasent changed as quick, it’s not as rich running as previous set up. Still see green in it with 200 miles

    I noticed it when I used brad penn too. I use Mobil 1 now and since fuel injection my oil stays cleaner much longer... Gotta love a fat carb.
