I know you can't judge things off 1 UOA, but....
Here's a link to my UOA:

So my question is, if I dropped 6 points off TBN over 2k miles, should I be using anything LESS than an HDEO? What about synths? I replaced this stuff w/ Pennzoil Platinum 5W30, would the TBN drop in it as fast as it did in the Castrol?
Viscosity wise, that lead MAY have been a one-time thing, but if it wasn't, should I stick w/ a heavy oil?
