I've about 1700 miles on my 393 stroker. I've changed the
oil 3 times now (last at 1000 miles). While checking the level tonight, the
oil seemed pretty black to me. I'm using Pennzoil 10-40 until I get about 5000 miles or so, then I'll switch over to Mobil 1. The question is, how black should the
oil be? I thought it would be light brown. I thought only old engines turned oil black. Should I be concerned about this or no?
Thanks
Scott, SPF #1230 / 393
