Will do 3K UOA on that one, then 5K.
Have you noticed increased deposits with M1 0w-40, or is this move because M1 ESP is formulated to minimize such deposits?
Why not go 5K on the first run of ESP?
Nah, I am not going to check deposits every time I do oil change etc. I switched because M1 ESP looks very good on paper, there were some testimonies that that oil left least amount of deposits on 2.0T in Audi Q5, and then there is Lubrizol study where Low-SAPS oils left 47% less deposits on intake valves and 167% less deposits on exhaust valves (VW504.00/507.00 oils).
You saw TBN in M1 0W40, it went down to 2.6, and it starts at 10.8. In M1 5W30 ESP it starts at 6! So I just want to be sure TBN is retained in sufficient numbers.
