Our gasoline sulfur content is 30 ppm max (aside from Cali), and even at this level people have reported rather quick TBN depletion with low SAPS oils such as M1 ESP. So, my advice for the OP would be to not run a very long OCI if he's going to use this oil. Might want to verify with a UOA.
What they have in most places is Europe is ultra-low sulfur gasoline with 10 ppm max. Supposedly EPA here in the US has mandated the same max level as of 2017, at which point we should be able to run such low SAPS oil at regular OCIs as well.
With that said, I'm not really sure why the OP wants to run this oil in his gasoline engine. There really is no benefit for him, as far as I can see, compared to a full SAPS oil.
