After my adventurous oil change tonight, I managed to collect my oil sample, and will faithfully mail it out tomorrow, and will anxiously await the results, including Dyson analysis and TBN, and will promptly post them on BITOG for all to see. I know some of you have been anxiously awaiting a good, recent UOA on TA, so I hope this helps. I know that I for sure am anxious to see how it did. I can tell you that it didn't lose or burn a drop during the interval (about 5300 miles) and came out pretty dark, almost black. And they were 98% highway miles, FWIW. This in the '02 Nissan Frontier 2.4L DOHC with now about 41K miles on it.
