Good stuff. Surprised he's on board with the SP add packs. Guys in racing are usually chasing high additive levels.Very, very smart guy. Talked to him when he worked at Joe Gibbs Racing about differential gear oil.
He repeated the TBN thing in I think it was his 3 Penzoil oils compared video as well.Lake Speed Jr just made some guys around here spin their heads off their shoulders with that video!!
Game changer
TBN not important
No need to spend money on that anymore
I was wondering that too. Good point."Tbn is a dinosaur. A relic of the past."
To be fair he is coming from a racing background & I doubt racers are interested in doing long extended drains (Where I believe TBN plays a better role). After some more digging I was reminded that BN & AN used together can be an excellent tool. Using these measurements is best to start with a virgin oil sample for BN & AN to reflect a starting point.
When the two converge (AN & BN) is around when iron wear rises more rapidly. Who wouldn't want this useful information if they could get it included, for little to no money, in a UOA? Why would this information, example below, not be helpful in analyzing used oil?
IMO it is far from unhelpful or unuseful. I'll go against the grain & disagree with his dinosaur comment.

Depends on what kind of racing.I forget, do racers change the oil after each race or rebuild/change engine and the oil?
It's significant enough. But getting pee in your panty liner when it goes from 7-8 to 3 in a year or two is just nuts.I knew TBN wasn't that significant, but I didn't know it was that insignificant.
... You just have to look at the big picture rather than just one parameter.
Other studies have been done that shows no correlation between TBN and TAN to engine wear. It's because of how the two tests are performed and the acid and base used for titration.
